Chipset datasheets. They are needed if you want to build a patch for the corresponding chipset setting. Otherwise, you don't need it. For the purpose of the sample modification in this chapter, you need the VIA 693A datasheet. It's available for download at http://www.rom.by in the PDF section. There is one more BIOS tool resource on the Internet that I haven't mention. It's called Borg number one's BIOS tool collection, or BNOBTC for short. It is the most complete BIOS tool collection online. However, its uniform resource locator (URL) sometimes moves from one host to another. Thus, you may want to use Google to find its latest URL. You learned about the IDA Pro disassembler, FASM, and hex editor in the previous chapters. Thus, modbin, cbrom, and the chipset datasheet remain. I explore them one by one. Start with modbin. Modbin is a console-based utility to manipulate Award system BIOS. You know that there are two flavors of modbin, one for each Award BIOS version. However, the usage of these tools are similar, just load the BIOS file into modbin and modify the system BIOS with it. Moreover, there is one "undocumented feature" of modbin that's useful for BIOS modification purposes: during modbin execution; when you start to modify the BIOS binary that's currently loaded, modbin will generate some temporary files. These temporary files are Award BIOS components. They are extracted by modbin from the BIOS binary file. Each of the two types of modbin generates different kinds of temporary files. However, both versions extract the system BIOS. Both also pack all temporary files into one valid Award BIOS binary when you save changes in modbin. Here are the details: 1. Modbin version 4.50.80C extracts the following components from an Award BIOS version 4.50PG binary: a. Bios.rom. It is the compressed version of last 128 KB of the BIOS file. It contains the compressed original.tmp, the boot block, and the decompression block. b. Original.tmp. It is the decompressed system BIOS. The execution of modbin 4.50.80C is shown in figure 6.1. 2 #################### File: A%20MACHINE%20MADE%20THIS%20BOOK%20ten%20sketches%20of%20computer%20science%20-%20JOHN%20WHITINGTON%20%28PDF%29.pdf Page: 178 Context: # Solutions ## 2 | | | | | | |---------|---------|---------|---------|---------| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ![Camel](https://example.com/camel-image) ### Grayscale | Color Shade | |-------------| | ![White](https://example.com/white) | | ![Light Gray](https://example.com/light-gray) | | ![Gray](https://example.com/gray) | | ![Dark Gray](https://example.com/dark-gray) | | ![Black](https://example.com/black) | #################### File: 10.24 big files.txt Page: 1 Context: 10.24 big files #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29.pdf Page: 81 Context: Chapter14KernelCanonicalCorrelationAnalysisImagineyouaregiven2copiesofacorpusofdocuments,onewritteninEnglish,theotherwritteninGerman.Youmayconsideranarbitraryrepresentationofthedocuments,butfordefinitenesswewillusethe“vectorspace”representationwherethereisanentryforeverypossiblewordinthevocabularyandadocumentisrepresentedbycountvaluesforeveryword,i.e.iftheword“theappeared12timesandthefirstwordinthevocabularywehaveX1(doc)=12etc.Let’ssayweareinterestedinextractinglowdimensionalrepresentationsforeachdocument.Ifwehadonlyonelanguage,wecouldconsiderrunningPCAtoextractdirectionsinwordspacethatcarrymostofthevariance.Thishastheabilitytoinfersemanticrelationsbetweenthewordssuchassynonymy,becauseifwordstendtoco-occuroftenindocuments,i.e.theyarehighlycorrelated,theytendtobecombinedintoasingledimensioninthenewspace.Thesespacescanoftenbeinterpretedastopicspaces.Ifwehavetwotranslations,wecantrytofindprojectionsofeachrepresenta-tionseparatelysuchthattheprojectionsaremaximallycorrelated.Hopefully,thisimpliesthattheyrepresentthesametopicintwodifferentlanguages.Inthiswaywecanextractlanguageindependenttopics.LetxbeadocumentinEnglishandyadocumentinGerman.Considertheprojections:u=aTxandv=bTy.Alsoassumethatthedatahavezeromean.Wenowconsiderthefollowingobjective,ρ=E[uv]pE[u2]E[v2](14.1)69 #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 165 Context: s.Thesesystemsareknownasonlineanalyticalprocessing(OLAP)systems.ThemajordistinguishingfeaturesofOLTPandOLAParesummarizedasfollows:Usersandsystemorientation:AnOLTPsystemiscustomer-orientedandisusedfortransactionandqueryprocessingbyclerks,clients,andinformationtechnologyprofessionals.AnOLAPsystemismarket-orientedandisusedfordataanalysisbyknowledgeworkers,includingmanagers,executives,andanalysts.Datacontents:AnOLTPsystemmanagescurrentdatathat,typically,aretoodetailedtobeeasilyusedfordecisionmaking.AnOLAPsystemmanageslargeamountsofhistoricdata,providesfacilitiesforsummarizationandaggregation,andstoresandmanagesinformationatdifferentlevelsofgranularity.Thesefeaturesmakethedataeasiertouseforinformeddecisionmaking. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 29 Context: rwithMorganKauf-mannPublishersatwww.booksite.mkp.com/datamining3e.Thesewebsitescontainmanysupplementalmaterialsforreadersofthisbookoranyoneelsewithaninterestindatamining.Theresourcesincludethefollowing:Slidepresentationsforeachchapter.LecturenotesinMicrosoftPowerPointslidesareavailableforeachchapter. #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29.pdf Page: 8 Context: viPREFACE #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 249 Context: ```markdown # INDEX - LA 2001 - Editor, 173 - LA 3001 - The Code, 132 - LA 3602 - Project Costing, 128 - LA 3899 - The Request constant genre, 139 - LA 3900 - Intermediary, 83 - LA 4001 - MODS, 128 - LA 4002 - Accessibility, 31 - LA 4003 - INTERLINK, 128 - LA 4100 - RACING, 60 - LA 4101 - Right Face Logo, 84 - LA 4102 - Budget Fundamentals, 61 - LA 4103 - Library, 128 - LA 4104 - Create X-Philanthropy, 115 - LA 4167 - JCPenney Format, 15 - LA 4200 - Help the Team, 155 - LA 4201 - Short & Bulky, 18 - LA 4202 - Evaluate a Marital Plan, 13 - LA 4204 - Causes of Phobias, 82 - LA 4210 - Channel Ports, 30 - LA 4299 - Shopping Don’s Day, 128 - LA 4300 - Marketplace, 154 - LA 4327 - Proximate End-Use, 202 - LA 4328 - C.A.

To do so, you can log plugin-related messages in the IDA Pro message pane with this function. Experienced C/C++ programmers will recognize that the msg function is similar to variations of the printf function in C/C++. Up to this point, the development of an IDA Pro plugin has been clear. However, you can develop another plugin that has a graphical user interface (GUI). It will be dialog based and use Windows message-loop processing during its execution. It will be more flexible than the script version. It is sometimes useful to have an easily accessible user interface for an IDA Pro plugin. That's why you will learn about that here. The plugin will use a lot of Windows application programming interface (Win32 API). Hence, I recommend that you read a book by Charles Petzold, Programming Windows (5th edition, Microsoft Press, 1998) if you haven't been exposed to Win32 API. Use Win32 API to create a dialog box for the IDA Pro plugin. The relevant material in Petzold's book for this purpose is found in chapters 1, 2, 3, and 11. A thorough explanation about the source code will be presented. Nevertheless, it'll be hard to grasp this without significant background in Win32 API. Start the plugin development. The first steps are just the same as explained in the previous plugin example. Proceed accordingly, until you can show a message in the IDA Pro message pane. Then, you have to modify three types of core functions in the IDA Pro plugin source code, i.e., init, term, and run. The term function is called when the plugin is in the process of being terminated, init is called when the plugin is being started (loaded to the IDA Pro workspace), and run is called when the plugin is activated by pressing its shortcut key or by invoking the plugin with RunPlugin in an IDA Pro script. Initialize the user interface inside init, and clean up the corresponding user interface resources during the termination process inside term. Let's get down to the code.

With this utility, you can read, erase, and verify the supported flash ROMs in the PCI expansion card directly in Linux. Ctflasher supports kernel versions 2.4 and 2.6. Currently, ctflasher only supports some network interface cards (NICs), the proprietary ctflasher card, the SiS 630 motherboard, and a flasher card that connects through the IDE port. The architecture of ctflasher is based on an LKM. Thus, to use it, you have to load the kernel module in advance. After the LKM has been loaded, you can access the flasher through the /proc interface by using the cat command. The HOWTO file from ctflasher version 3.5.0 explains the usage as follows: First do a "make all." All modules will be placed in modules. Do a "cd modules." There should be 8 files. For kernel 2.4, these files are flash.o -- The main module, containing algorithms for programming flashprom ct.o -- Low-level driver for ctflasher ide_flash.o -- Low-level driver for ide-flasher e100_flash.o -- Low-level driver for Intel nic e100 3c90xc_flash.o -- Low-level driver for Intel nic 3c905c rtl8139_flash.o -- Low-level driver for Realtek nic 8139 sis630_flash.o -- Low-level driver for north–southbridge SiS 630 (BIOS) via-rhine_flash.o -- Low-level driver for via Rhine nic While for kernel 2.6, these files are flash.ko -- The main module, containing algorithms for programming flashprom ct.ko -- Low-level driver for ctflasher ide_flash.ko -- Low-level driver for ide-flasher e100_flash.ko -- Low-level driver for Intel nic e100 3c90xc_flash.ko -- Low-level driver for Intel nic 3c905c rtl8139_flash.ko -- Low-level driver for Realtek nic 8139 sis630_flash.ko -- Low-level driver for north–southbridge SiS 630 (BIOS) via-rhine_flash.ko -- Low-level driver for via Rhine nic You must load the main module "flash.o" and the low-level driver (for example, ct.o). It doesn't matter what order the modules are loaded in.

Beside the IOCTL code, DeviceIoControl has some pointer-to-void parameters10 used by user-mode applications to exchange data with device drivers. Because the parameters are pointer-to-void, you can set the pointer to point to anything. Thus, to make these parameters usable, you have to define some data structures that will be used by the user-mode application and the device driver. You use the pointer-to-void in DeviceIoControl to point to an instance of this data structure. To do so, you cast the pointer-to-void to pointer-to-your-data-structure and manipulate the contents of the data structure instance with the latter pointer. These data structures are defined in listing 9.8 with a typdef struct keyword, for example, as follows: typedef struct _IO_LONG { unsigned short port32; unsigned long value32; }IO_LONG; Continuing the "phone number" analogy that I mentioned before, you can think of the content of these data structures as the "conversation" between the user-mode application and the device driver. Note that in the bios_probe device driver, every IOCTL code is associated with one data structure, but not the other way around. For example, IOCTL_READ_PORT_LONG is associated with IO_LONG data structure; IOCTL_WRITE_PORT_LONG is also associated with IO_LONG. Both IOCTL_READ_PORT_BYTE and IOCTL_WRITE_PORT_BYTE are associated with IO_BYTE. And so on. Proceed to the most important part of the bios_probe device driver.

While this card wouldn't gain any of the configuration benefits related to full hardware Plug and Play cards, it would allow Plug and Play software to determine the device's configuration and thus ensure that Plug and Play cards will map around the static SCSI board's allocated resources. ## Option ROM Initialization The system BIOS will determine if the option ROM it is about to initialize supports the Plug and Play interface by verifying the structure revision number in the device's Plug and Play header structure. For all option ROMs compliant with the "Plug and Play BIOS Specification, version 1.0", the system BIOS will call the device's initialization vector with the following parameters: | Register Value on Entry | Description | |-------------------------|-----------------------------------------------------------------------------------------------| | ES:DI | Pointer to system BIOS PnP installation check structure. | | BX | CSN for this card, ISA PnP devices only.

UEFI binaries consist of UEFI drivers, UEFI applications, UEFI boot code and an optional operating system loader. UEFI driver can be regarded as replacement for the legacy PCI option/expansion ROM that is used to initialize expansion cards and on-board devices. However, some UEFI drivers act as bus drivers that are used to initialize the bus in the system. It’s more like a “pre-boot” version of the device driver usually found inside a running operating system. UEFI applications are software applications that run in the UEFI pre-boot environment, for example the operating system loader. UEFI boot code is the code in the UEFI-compliant firmware that loads the operating system loader to main memory and executes the operating system. The operating system loader can be implemented as part of the UEFI binaries as value-added implementation. In this respect, the operating system loader is regarded as UEFI application. Recall from figure 15.2, in an UEFI-compliant system, the mass storage device—part of the platform hardware—contains an UEFI system partition. This partition is a custom partition in the mass storage device that stores some of the UEFI binaries, particularly those that relate directly with the loading of the operating system loader. Moreover, value-added UEFI application can be stored in this partition too. The UEFI system partition is a mandatory part of a UEFI-compliant system because it’s required by UEFI-compliant firmware to boot from mass storage device1. Figure 15.3 show that one of the steps carried out by UEFI boot manager is initializing UEFI images. UEFI images in figure 15.3 consist of UEFI drivers and UEFI applications. Note that the operating system loader in figure 15.3 is also an UEFI application, even if it’s not shown explicitly in the image. Therefore, it’s also an UEFI image. UEFI images are a class of files defined by UEFI specification that contain executable code. The executable format of UEFI images is PE32+. It’s derived from Microsoft’s Portable Executable (PE) executable format. The “+” sign denotes that the PE32+ provides 64-bit relocation “fix-up” extension to standard PE32 format. Moreover, this executable format also uses a different signature to distinguish it from standard PE32 format. At this point, it’s unclear, how the image is executed in an UEFI-compliant system. UEFI specification explains about the execution environment in which UEFI images are executed in detail. I provide the relevant snippets from the specification in the following citation. 2.3 Calling Convention Unless otherwise stated, all functions defined in the UEFI specification are called through pointers in common, architecturally defined, calling conventions found in C compilers. … 2.3.2 IA-32 Platforms All functions are called with the C language calling convention. The general-purpose registers that are volatile across function calls are eax, ecx, and edx. All other general-purpose registers are nonvolatile and are preserved by the target function. In addition, unless otherwise specified by the function definition, all other registers are preserved. Firmware boot services and runtime services run in the following processor execution mode prior to the OS calling ExitBootServices(): 1 Mass storage device is also called block device in some documentations. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 114 Context: HAN09-ch02-039-082-97801238147912011/6/13:15Page77#392.4MeasuringDataSimilarityandDissimilarity77datadescribedbythethreeattributesofmixedtypesis:00.8500.650.8300.130.710.790.FromTable2.2,wecanintuitivelyguessthatobjects1and4arethemostsimilar,basedontheirvaluesfortest-1andtest-2.Thisisconfirmedbythedissimilaritymatrix,whered(4,1)isthelowestvalueforanypairofdifferentobjects.Similarly,thematrixindicatesthatobjects1and2aretheleastsimilar.2.4.7CosineSimilarityAdocumentcanberepresentedbythousandsofattributes,eachrecordingthefrequencyofaparticularword(suchasakeyword)orphraseinthedocument.Thus,eachdocu-mentisanobjectrepresentedbywhatiscalledaterm-frequencyvector.Forexample,inTable2.5,weseethatDocument1containsfiveinstancesofthewordteam,whilehockeyoccursthreetimes.Thewordcoachisabsentfromtheentiredocument,asindicatedbyacountvalueof0.Suchdatacanbehighlyasymmetric.Term-frequencyvectorsaretypicallyverylongandsparse(i.e.,theyhavemany0val-ues).Applicationsusingsuchstructuresincludeinformationretrieval,textdocumentclustering,biologicaltaxonomy,andgenefeaturemapping.Thetraditionaldistancemeasuresthatwehavestudiedinthischapterdonotworkwellforsuchsparsenumericdata.Forexample,twoterm-frequencyvectorsmayhavemany0valuesincommon,meaningthatthecorrespondingdocumentsdonotsharemanywords,butthisdoesnotmakethemsimilar.Weneedameasurethatwillfocusonthewordsthatthetwodocu-mentsdohaveincommon,andtheoccurrencefrequencyofsuchwords.Inotherwords,weneedameasurefornumericdatathatignoreszero-matches.Cosinesimilarityisameasureofsimilaritythatcanbeusedtocomparedocu-mentsor,say,givearankingofdocumentswithrespecttoagivenvectorofquerywords.Letxandybetwovectorsforcomparison.UsingthecosinemeasureasaTable2.5DocumentVectororTerm-FrequencyVectorDocumentteamcoachhockeybaseballsoccerpenaltyscorewinlossseasonDocument15030200200Document23020110101Document30702100300Document40100122030 #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 93 Context: # RTC (Standard) RAM Bank | Index | Name | |--------|-----------------| | 00h | Seconds Alarm | | 01h | Seconds | | 02h | Minutes | | 03h | Minutes Alarm | | 04h | Hours | | 05h | Hours Alarm | | 06h | Day of Week | | 07h | Day of Month | | 08h | Month | | 09h | Year | | 0Ah | Register A | | 0Bh | Register B | | 0Ch | Register C | | 0Dh | Register D | | 0Eh | 7th–11th Bytes of User RAM | Accessed using an indexed scheme.

Software must preserve the value of bit 7 at I/O addresses 70h. When writing to this address, software must first read the value, and then write the same value for bit 7 during the sequential address write. Note that port 70h is directly readable. The only way to read this register is through ALI access mode. If the NMIs enable is not changed during normal operation, software can alternatively read this bit once and then retain the value for all subsequent writes to port 70h. The RTC contains two sets of indexed registers that are accessed using the two separate Index and Target registers (70h/71h or 72h/73h), as shown in Table 147. --- Furthermore, the LPC bus specification defines the usage of motherboard-specific I/O resources.

IDA Pro scripts recognize only one type of variable, i.e., auto. There are no other variable types, such as int or char. The declaration of variable in an IDA Pro script as follows: auto variable_name; 2. Every statement in an IDA Pro script ends with a semicolon (;), just like in the C programming language. 3. A function can return a value or not, but there's no return-type declaration. The syntax is as follows: static function_name(parameter_1, parameter_n, ...) 4. A comment in an IDA Pro script starts with a double slash (//). The IDA Pro scripting engine ignores anything after the comment in the corresponding line. // comment statement; // comment 5. IDA Pro "exports" its internal functionality to the script that you build by using header files. These header files must be "included" in the script so that you can access that functionality. At least one header file must be included in any IDA Pro script, i.e., idc.idc. The header files are located inside a folder named idc in the IDA Pro installation directory. You must read the *.idc files inside this directory to learn about the functions exported by IDA Pro. The most important header file to learn is idc.idc. The syntax used to include a header file in an IDA Pro script is as follows: #include < header_file_name> 6. The entry point of an IDA Pro script is the main function, just as in the C programming language.

However, this chapter covers the BIOS level implementation of the WBEM paradigm. Therefore, the operating system–specific layer of WBEM will not be the major theme here. Even if figure 10.1 shows a kind of client–server relationship between the WBEM manager software and the system that hosts the manageable components, in the real world, the system doesn't have to be set up as client and server for the WBEM to work. For example, in Windows machines, as long as remote access to the WMI of the remote machine is granted, the local machine can "ask" the remote machine to perform management tasks. The requirements and specifics about WBEM for hardware devices are available in the "Windows Hardware Instrumentation Implementation Guidelines" at http://download.microsoft.com/download/5/7/7/577a5684-8a83-43ae-9272-ff260a9c20e2/whiig-1.doc. The SMBIOS implementation guideline is provided in chapter 2.7 in the document: Static SMBIOS table data is provided to WMI using the WMI infrastructure Required Vendors who want to provide OEM-specific and system-specific instrumentation data may choose to use SMBIOS as the mechanism. In order to leverage the capabilities of the WMI infrastructure to surface this SMBIOS data, they must conform to any SMBIOS version from 2.0 to 2.3. Doing so will allow the Win32 provider to populate almost all of the SMBIOS-provided information into the [Common Information Model] CIMv2.0 namespace. In particular, almost all of the information will be put into Win32 classes. Some of these Win32 classes are derived from the CIMv2.0 physical [Managed Object Format] MOF. This requirement does not imply a requirement to implement SMBIOS in a system. It's clear in the preceding citation that the WMI subsystem in Windows will "parse" the SMBIOS data provided by the BIOS and then "export" it to the WBEM manager software as needed through the WMI interface. In figure 10.1, an arrow runs from the power-on BIOS code to the SMBIOS structure tables. This arrow means the SMBIOS structures table is populated by the BIOS code that is executed during system initialization. SMBIOS is a BIOS feature specific to the x86 platform. It's implemented as part of the WBEM initiative. The role of SMBIOS is to provide system-specific information to the upper layer in the WBEM implementation, i.e., the operating system layer. To easily understand the SMBIOS, you can download version 2.4 of its specification at http://www.dmtf.org/standards/smbios/. I often refer to the contents of this specification. In the earlier implementation of SMBIOS, the information was presented as a "callable interface," i.e., platform-specific function calls.

Fortunately, it does have a scripting feature. The standard and advanced editions of IDA Pro 4.3 differ from this freeware edition. They come with plugin support and support for more processor architecture. You will learn how to use the scripting feature in the next section. Use the IDA Pro freeware version to open a BIOS binary file. First, the IDA Pro freeware version has to be installed. After the installation has finished, one special step must be carried out to prevent an unwanted bug when this version of IDA Pro opens a BIOS file with *.rom extension. To do so, you must edit the IDA Pro configuration file located in the root directory of the IDA Pro installation directory. The name of the file is ida.cfg. Open this file by using any text editor (such as Notepad) and look for the lines in Listing 2.1.

A modeless dialog box is created to lump various tasks in one user interface. Note that the dialog box is created only once during the disassembling session in the run function. It will be hidden or shown based on user request. The run function is called every time the user activates the plugin. The task to show the plugin dialog box is accomplished by run, whereas the task to hide it is accomplished by the window procedure for the plugin dialog box, i.e., the plugin_dlg_proc function. The message handler for the plugin dialog box's WM_CLOSE message is responsible for hiding the dialog. This message handler is inside the dialog box window's procedure plugin_dlg_proc at the following lines: case WM_CLOSE: { ShowWindow(hwnd_dlg, SW_HIDE); }return TRUE; The resources used by this plugin are cleaned up by the term function. This function is called upon the plugin termination or unloading process. It destroys the window and sets the corresponding dialog box handle to NULL as shown at the following lines: void idaapi term(void) { DestroyWindow(h_plugin_dlg); h_plugin_dlg = NULL; // Irrelevant line(s) omitted } The bulk of the work accomplished by the plugin's user interface is in the plugin_dlg_proc function.

This SBC has an on-board AMD Geode GX1 or Geode GLXL-V20 processor. Geode is a family of x86 processors produced by AMD for embedded applications. You can download the relevant datasheets for the AMD Geode GX processor family at [AMD Geode GX information](http://www.amd.com/us/en/ConnectivitySolutions/ProductInformation/0,,50_2330_9863_9919,00.html). The chipset used in Advantech PCM-S822 is CX5530, a custom chipset for the AMD Geode GX processor family. Advantech PCM-S822 SBC comes preloaded with a BIOS based on Award BIOS version 4.50PG. The BIOS is much like the standard Award BIOS 4.50 that you can find on desktop PCs produced around 1998–2000. You can download the BIOS for Advantech PCM-S822 at [Advantech BIOS Download](http://www.advantech.com/support/detail_list.asp?model_id=PCM-S822). It's quite easy to modify the BIOS in this SBC because it uses the "standard" Award BIOS 4.50. Therefore, the modification tools for it are available in the public domain. The BIOS on this SBC is vulnerable to a code injection attack because of the usage of Award BIOS 4.50. Some vendors have customized the BIOS before using it in a POS device. However, it is usually still vulnerable to BIOS code injection because most customization is only carried out to reduce the boot time—removing certain checks during POST, changing the boot logo, and perhaps hard-coding some BIOS options. These customizations don’t protect the BIOS against code injection attacks. Performing an attack on a POS device based on this SBC is difficult because the operating system running on it is customized for the embedded system, such as Windows CE or embedded Linux. Nonetheless, becoming accustomed to the API of those operating systems is trivial for an experienced system programmer because those operating systems are descendants of their desktop or server counterpart. The POS vendors choose to use Windows CE or embedded Linux because of the versatility, quick development time, and cost efficiency. In most cases, upon seeing a POS device, you wouldn’t be able to recognize its operating system. Nevertheless, you might see it clearly when the POS is out of service. #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 575 Context: # AMI UEFI-compliant Products Roadmap (Forecast) AMI states in its whitepaper that it uses the so-called AMI Visual eBIOS development environment to develop the current generation of BIOS-related software. This development environment speeds up BIOS-related software development compared to the DOS-based tools used in the previous generation of software produced by AMI. At the moment, AMI still produces AMIBIOS BIOS for its customers—the motherboard makers such as Gigabyte, DFI, etc. Nevertheless, it provides a seamless migration path to UEFI-based implementation in the future due to the modularity of AMIBIOS. The explanations about AMI EFI/UEFI products give us a glimpse over the future of BIOS-related products from AMI. I summarize them in Figure 15.4. ![Figure 15.4 AMI UEFI-compliant products roadmap (forecast)](link-to-image) ## Current and Future Products - **AMIBIOS-based products for desktop and server** - Gradual migration to UEFI-compliant code base - **AMI Aptio-based products** - Minor changes from EFI-compliant to UEFI-compliant code base - **Future AMI BIOS products for desktop and server** - **AMI Enterprise64 BIOS** - Minor changes from EFI-compliant to UEFI-compliant code base - **Future AMI Enterprise64 BIOS products** - **AMI Pre-Boot Applications (PBA)** - Minor changes from EFI-compliant to UEFI-compliant code base - Development of new value-added AMI Pre-Boot Applications - **Future AMI Pre-Boot Applications** Note that Figure 15.4 is only my forecast; it may not turn out like this forecast in the real world. I provide this forecast because AMI hasn’t released any document regarding their product roadmap to the public. Now is the time to look at another big firmware vendor in desktop, server, mobile, and embedded fields, Phoenix Technologies. Phoenix has broad product offerings that utilize EFI/UEFI technologies. All of those products are based on the so-called Core System Software (CSS). The products are even marketed under the TrustedCore name, the exact naming as follows: 1. **TrustedCore Server & Embedded Server** for server applications 2. **TrustedCore Embedded** for embedded

operating system for embedded x86 systems developed by Elegant Technologies. The boot process of this motherboard is illustrated in Figure 14.5. ``` Power-on/reset BIOS boot block execution Read boot setting from CMOS | v Boot to etBIOS? / \ YES NO | | v v Load etBIOS from Load desktop/server OS from BIOS chip to RAM secondary storage device to RAM | v Execute etBIOS OS | v Execute desktop/server OS ``` **Figure 14.5 Boot process in systems with etBIOS** Figure 14.5 shows that the boot process is much like that for an ordinary BIOS because the boot setting is stored in the CMOS chip. The CMOS setting determines whether to boot to a desktop or server operating system or to etBIOS. etBIOS has the capability to play audio CDs and DVDs out of the box. These features are provided by etDVD and etBrowser, which exist as part of the etBIOS module by default. Sample screenshots of these features are shown in Figures 14.6 and 14.7, respectively. 1 The Elegant Technologies website is at [http://www.elegent.com/index.htm](http://www.elegent.com/index.htm). #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 185 Context: HAN11-ch04-125-186-97801238147912011/6/13:17Page148#24148Chapter4DataWarehousingandOnlineAnalyticalProcessingconcepthierarchyfortimedefinedas“daybuild BUILD: Adding /r to COPYOBJ so copy ops won't hang.

For example, the t character is stored as 74h and 14h. 74h is the ASCII code for the t character and 14h is its scan code. I don't know why the characters of the password are repeated in the keyboard buffer; perhaps it's for Unicode compatibility. Nonetheless, when the password string consists of eight or more characters, the keyboard buffer is not large enough to store all of the characters. Hex dump 11.2 shows this when I set the BIOS password to "destruct" in my motherboard. Hex dump 11.2 BDA Keyboard Buffer When the BIOS Password Is "Destruct" Address Hexadecimal Value ASCII Value 00000000 0D1C 0D1C 6512 6512 731F 731F 7414 7414 ....e.e.s.s.t.t. 00000010 7213 7213 7516 7516 632E 632E 7414 7414 r.r.u.u.c.c.t.t. As you can see in hex dump 11.2, the string of password characters stored in the keyboard buffer in the BDA is incomplete; the keyboard buffer only shows "estruct," yet the complete password is "destruct." I tried to enter "estruct" during the BIOS password request at boot time. It did not work. That means that Award BIOS version 6.00PG in my machine validates the entire BIOS password. Now, I show you how to dump the BDA in Linux. It's quite easy to implement. Nonetheless, some quirks from the Linux's mmap function must be handled correctly to make the program works flawlessly. I name this small utility bda_dump. The overall source code of this application is shown in listing 11.8. The bda_dump utility must be executed with a root account; otherwise, you won't receive enough permission and the program will fail.

To use the script in listing 8.1, open the ROM binary starting at segment 0000h and offset 0000h in IDA Pro. You can't know the exact loading segment for any expansion ROM because it depends on the system configuration. The system BIOS is responsible for system-wide address space management, including initializing the base address for the XROMBARs and loading and initializing every PCI expansion ROM in the system. That's why you load the binary in segment 0000h. Actually, any segment is OK; it won't make a difference. Furthermore, as shown later, every data-related instruction would use references based on the code segment.4 You have to disassemble the binary in 16-bit mode, because the processor is running in real-mode during expansion ROM initialization. The result of parsing rpl.rom with IDA Pro script is in listing 8.1.

The base address is then added to the value in IP to form the physical address into memory. As a result, the processor can only address the first 1 MiByte of memory when in real mode. However, immediately following RESET or INIT, the CS selector register is loaded with 0x00, but the CS base address is not formed by left-shifting the selector. Instead, the CS base address is initialized to 0xFFFF0000. IP is initialized to 0xFFFE. Therefore, the first instruction fetched from memory is located at physical-address 0xFFFF0000 (0xFFFF0000 + 0xFFFE). The CS base address remains at this initial value until the CS selector register is loaded by software. This can occur as a result of executing a far jump instruction or call instruction, for example. When CS is loaded by software, the new base-address value is established as defined for real mode (by left-shifting the selector value four bits). From the preceding references, you should conclude that address `0x0000_0000-0x0000_FFFF` is an alias to address `0xFFFF_0000-0xFFFF_FFFF`, i.e., they both point to the same physical address range. Whenever the host (CPU) accesses some value in the `0x0000_0000-0x0000_FFFF` address range, it's actually accessing the value in the `0xFFFF_0000-0xFFFF_FFFF` range, and the reverse is also true. From this fact, I know that I have to relocate 64 KB of the uppermost BIOS code to address `0x0000_0000-0x0000_FFFF` for further investigation. This decision is made based on my previous experience with various BIOS binary files; they generally reference an address with `0x000` used as the segment value within the BIOS code. Also, note that the last 64 KB of the BIOS binary file are mapped to last 64 KB of the 4 GB address space, i.e., 4 GB-64 KB to 4 GB. That's why you have to relocate the last 64 KB. This addressing issue will be covered in depth in the first section of chapter 5. Thus, if the concept remains too hard to grasp, there is no need to worry about it. A simple script of only several lines can be typed and executed directly within IDA Pro without opening a text editor. IDA Pro provides a specific dialog box for this purpose, and it can be accessed by pressing `Shift+F2`. This is more practical for a simple task, but the number of lines in the routine grows, you might consider coding the script as described in the previous explanation because there is a limitation on the number of instructions that can be entered in the dialog box. In this dialog box, enter the script to be executed and click `OK` to execute the script.

Additional requirements: • All backdoors (if any) for unsecured BIOS updates must be closed (no boot-block-based BIOS recovery unless the CRTM is locked and immutable). • Optionally, non-CRTM regions of the flash part may be selectively chosen to be not locked down for any OEM/ODM-specific purposes. • Implement a "rollback protection" policy where an authorized user (e.g., an administrator or supervisor) could choose (preferably only once) to allow or block an older version of BIOS. Now, I move forward to show you how the preceding points are being implemented in the Phoenix TrustedCore BIOS products. Phoenix implemented the concept by combining both the BIOS binary and the BIOS flasher program into one "secure"4 BIOS flasher executable. It's still unclear whether there is a non-Windows version of this binary; I couldn't find any clues about that Phoenix documentation. What follows is the logical diagram of the BIOS flashing procedure for Phoenix TrustedCore binaries. This logical diagram is a reproduction of the logical diagram in the Phoenix TrustedCore white paper. 4 The combined BIOS binary and BIOS flasher software is supposed to be secure. However, someone might be able to break its protection in the future. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 70 Context: ypes.Advanceddatatypesincludetime-relatedorsequencedata,datastreams,spatialandspatiotemporaldata,textandmultimediadata,graphandnetworkeddata,andWebdata.Adatawarehouseisarepositoryforlong-termstorageofdatafrommultiplesources,organizedsoastofacilitatemanagementdecisionmaking.Thedataarestoredunderaunifiedschemaandaretypicallysummarized.Datawarehousesystemspro-videmultidimensionaldataanalysiscapabilities,collectivelyreferredtoasonlineanalyticalprocessing. #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 568 Context: available BIOS binary before trying to compromise systems that use the operating system. You have to reverse engineer the binary because there's no public domain documentation that plays a role similar to that of MSDN as Windows documentation. The next problem that attackers face is how to "inject" their code into the embedded x86 BIOS in the system so that the BIOS will not be broken. This is not a big deal for systems with Award BIOS because the code injection method is already known. For example, Acorp 4865GQET uses Award BIOS 6.00PG as its base code, so it's trivial to inject code into it. The same is true for the Advantech PCM-5822 because it uses Award BIOS 4.50PG. Moreover, the BIOS version used in embedded x86 versions always seems to be an older version compared to its desktop counterpart. As for BIOSs from other vendors, there's no published code injection method; nevertheless, the possibility is there, waiting to be exploited. #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 363 Context: Before I show you the content of these new files, I explain the changes that I made to accommodate this new feature in the other source code files.

This is not a trivial task for people new to IDA Pro. That's why it's presented in a step-by-step fashion. However, the output in the workspace is not yet usable. The next step is learning the scripting facility that IDA Pro provides to make sense of the disassembly database that IDA Pro generates. ## 2.3 IDA Pro Scripting and Key Bindings Try to decipher the IDA Pro disassembly database shown in the previous section with the help of the scripting facility. Before you proceed to analyze the binary, you have to learn some basic concepts about the IDA Pro scripting facility: IDA Pro script syntax is similar to the C programming language. The syntax is as follows: 1. **Basic Structure** - Start with a function definition. - Use semicolons to end each statement. - Use curly braces `{}` to define the scope of functions. 2. **Variables** - Declare variables with their types (e.g., `int`, `char`, `float`). - Example: `int x;` 3. **Control Structures** - Use `if`, `for`, and `while` as in C. 4. **Functions** - Functions are defined similarly to C. 5. **Comments** - Use `//` for single-line comments. - Use `/* comment */` for multi-line comments. By mastering these basics, you will be better prepared to write scripts that allow you to leverage the full power of IDA Pro's analysis capabilities. #################### File: A%20MACHINE%20MADE%20THIS%20BOOK%20ten%20sketches%20of%20computer%20science%20-%20JOHN%20WHITINGTON%20%28PDF%29.pdf Page: 142 Context: 128Chapter9.OurTypefaceThediagramshowsvariousalternativecharactersfor“d”and“g”intheZapfinotypeface.Youcanseethatsomesuitthewordmorethanothers.Inparticular,inthebottom-rightexample,theinitial“d”clashesawfullywiththenextletter.Beforecomputers,whentypewassetmanuallyusinglittlemetalpiecesarrangedintorows,smearedinink,andpressedontopaper,itwasnaturalforatypefacetohaveslightlydifferentglyphdesignsforeachsize.Aheadlinewouldhaveasubtlydifferentcharacterdesigntonormalsizedtext,andagaindifferenttothesortoftinytextusedforfootnotes.Partofthisisduetotheessentialopticalcharacteristicsofsmallshapes:itiseasiertoreadasmalltypefaceifithasproportionallywidercharactersthanitsnormalsize,forexample.Partofithastodowiththephysicalcharacteristicsoftheinkandpaper:inkspreads,andthewayitspreadsleadstothesamemetalshapeshowingdifferentlyatdifferentsizes.Whendesigningatypefacebycomputer,however,itistemptingtotakeashortcut:designthetypefaceonce,andthenautomaticallyscaleittowhateversizeisneededbysimplearithmeticonitscoordi-nates.Now,wehaveanysizeavailable,anddesigningthetypefaceischeaper.Thisshortcutwasnotavailabletothemetaltypeman-ufacturer.However,manygoodmoderncomputertypefacesstillhavemultipleso-calledopticalsizes.Theymayhaveseparateshapesfor5pt,8pt,10pt,12pt,and16pt,forexample.Wecanusethecom-puterscalingmethodinbetweensizes–toobtain11pt,forexample.FigureAontheoppositepageshowsaphraseprintedintheLatinModerntypeface,atfivedifferentsizes.Below,thesamephrasehasbeenrepeated,butscaleduptoshowthedifferencesclearly.WehavenotyetlookedattheotherthreefacesofthePalatinotypeface:theBold,theItalic,andtheBoldItalic.Aboldtypefaceisonewhichisthicker,usingmoreink.TheItalichasadifferent,slopingshape.Bothareusedforemphasis.YoucanseeBoldandItalicusedinvariousplacesinthisbook,butwedon’tuseBoldItalic.Thevariousshapesaredesignedtoworkcomfortablytogether.ShapeShapeShapeShape #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 356 Context: /proc/.../erase The "..." stand for the hardware-dependent part of the path: ct.o ctflasher ide_flash.o ide-flasher/PLCC32 and ide-flasher/DIL32 e100_flash.o e100-flash/device? 3c90xc_flash.o 3c90xc-flash/device? rtl8139_flash.o rtl8139-flash/device? sis630_flash.o sis630-flash via-rhine_flash.o via-rhine-flash/device?
