Now, you likely have grasped the basic idea of eBIOS. It's time to explore the technical details. I start with the Acorp 486SGQET BIOS binary. I use BIOS version 1.4 for this motherboard; the date of the BIOS is August 19, 2004. This BIOS binary is Award BIOS 6.00PG with eBIOS as one of its components. The size of the binary file is 512 KB. The layout of the components is shown in Figure 14.9. ![Figure 14.8 eBIOS browser screenshot](https://link-to-image.com/image14-8) *Figure 14.8 eBIOS browser screenshot (courtesy of Elegant Technologies)* Image Analysis: 1. **Localization and Attribution:** - **Image 1:** Located at the center of the page, labeled as "Figure 14.8 EBIOS browser screenshot (courtesy of Elegent Technologies)." 2. **Object Detection and Classification:** - **Image 1:** - **Objects:** Computer screen showing a browser interface. - **Classification:** Technology, Software. - **Key Features:** A screenshot of a browser displaying possibly technical data with charts and tabs. 3. **Scene and Activity Analysis:** - **Image 1:** - The scene shows a digital interface likely related to technical analysis or monitoring. Charts and a browser toolbar are present, indicating activities such as data analysis or system monitoring. 4. **Diagram and Chart Analysis:** - **Image 1:** - The chart depicted shows a line graph with various fluctuations, possibly representing performance metrics over time. - **Axes:** The x-axis likely represents time, while the y-axis shows a numerical value (perhaps frequency, percentage, or index level). - **Key Insights:** An upward trend is noticeable, indicating growth or improvement in the tracked metric. 5. **Text Analysis:** - The text below the image explains the use of eBIOS with some systems, providing background on technical details. It introduces specifics about the Acorp 4865QGET BIOS binary and highlights its components such as Award BIOS 6.00PG and its size. 9. **Perspective and Composition:** - **Image 1:** - The image captures a frontal view of a computer screen, maintaining clarity in displaying interface elements and charts. 13. **Graph Numbers:** - **Image 1:** Exact data points are not specified, but the graph likely includes numerical data on the y-axis, showing fluctuations over time on the x-axis. 15. **Contextual Significance:** - The image supports the document's explanation of technical configurations related to eBIOS and BIOS versions, providing a visual reference to the concepts discussed in the text below. #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 419 Context: The password string in the keyboard buffer is stored as ASCII characters paired with keyboard scan codes. 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.

Finally, look for the chipset register setting explanation. The chipset register setting will determine the overall performance of the motherboard when the BIOS has been executed. When a bug occurs in a motherboard, it's often the chipset register value initialization that causes the trouble. You may want to look for additional information. In that case, just proceed on your own. 5 #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 407 Context: 00000090 0020 0020 0000 0420 0400 0103 0F02 290F . . ... ......). 000000A0 0000 FFFB EBBF 038E 6400 FA0B D007 4104 ........d.....A. 000000B0 0A00 0B00 FFFF 536F 636B 6574 2034 3738 ......Socket 478 000000C0 0049 6E74 656C 0049 6E74 656C 2852 2920 .Intel.Intel(R) 000000D0 4365 6C65 726F 6E28 5229 2043 5055 0000 Celeron(R) CPU.. ........

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.

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.
