There is, however, a 975X7AB-2.0-8EKRS2H version of my motherboard, which makes the correct identification of my motherboard very important when it comes to finding and downloading the correct BIOS update file. Failing to research or understand the BIOS update details Even properly researching the changes in the BIOS upgrades may not be enough to completely understand exactly was changed.
Often these BIOS upgrade notes are written by techs with little or poor knowledge of English and rarely are the details noted in full. Even after learning that an E6400 is an Intel Core 2 Duo CPU and S3 is one of four sleep functions in the PC's power settings, you then need to know if you have an E6400 CPU.
You might be able to get the information by entering the serial number of the PC on a Web site, but when it comes to flashing your BIOS you need to be 100 percent accurate and the information on the Web site could be incorrect.
You can also get pertinent information from the initial POST screen.As a rule of thumb if your computer is operating normally, leave it alone.If you are unsure if a BIOS update will fix a problem that you are having with your PC, you can ask for more information from the manufacturer.Hello, I have this problem when trying to upgrade from Windows Vista (ultimate) to Windows 7 (ultimate), and it tells me that I need to upate the BIOS. I have a Dell XPS-M1530, trying to update from BIOS A08 to A9 (1530_A09.exe) or A12 (1530_A12.exe). My tech friend says he cannot understand why the Windows 7 upgrade program is asking to update the BIOS before it will load. I can download the BIOS file from Dell, but when I try to execute I get the following error: "An unexpected error occurred while trying to execute the flash application. Application error return 0x00000406" I reboot and no help.
