Nice. I have a question: on an old dell optiplex G520 can I upgrade bios from A10 to newer in order to boot from uefi as well?

[lenholton]

Excellent clear concise video... I missed the instruction to use the tab key in the final step first time around and the update failed. Using the tab key as instructed made ALL the difference. Thank you for a very useful video!

Any clue why it's telling me "this program cannot be run in dos mode" when I go to run the BIOS update? It also shortens the name of the update file from what it was in Windows

Is there a DOS program to read & print the bios information? I'm most interested getting the serial number. A bootable linux usb drive would also be ok.

Im trying to use this method to update my bios with a modified rom file. However i keep getting errors. In the research ive done i need an afudos.exe as well as the rom in the drive but everytime i boot freedos its a new error.

Do you know how to do it like this without error? Idk if i have the wrong version of afudos or what

Tab is not working for me. When I am pressing tab the blink dash moves to next character.

At 5:00 to 5:20 you talk about "Booting to DOS" & are gonna show us.... but I missed that part. My PC boots to Windows 7, not DoS. Guess I have to google a different video or such. Then, on figuring out booting from USB, it booted to Windows again and again until I disabled the SSD with Windows on it. Then on USB Boot, all I got was "Syntax error Syntax error Syntax error Syntax error" etc etc etc. Will look for someone who explains more.

Im trying to update a gigabyte board.

There are x3 files in the download needed for bios update.
The x3 files are an autoexe.bat, efiflash.exe, and z87xud3h.F9

Obviously the .F9 file is the bios file, but loading this via Freedos like you did, i get as far as where it lists the x3 files and it just sits there doing nothing.

What file do i launch, and how do i launch it while dos is running 🤔

Do i even need all the files?
