A guidance how to create a bootable USB-Stick / Pendrive (incl. MS-DOS system files) to perform a BIOS update.
The following tools are needed:
Instruction to create a bootable USB-Stick
Starting the BIOS-Update from USB-Stick
First, go into your BIOS-Setup and change the Bootsequence to USB-Stick/Drive (search for an option like Bootsequence, First Boot Device, or something similarly).
Insert the USB-Stick and restart your PC. If all went well - MS-DOS starts and you can see the famous DOS-Prompt (C:\>).
Now you can start the BIOS update. Remember: it's a good idea to backup the old BIOS version.

If you cannot boot from USB you should try a boot CD/Diskette, or an other USB pen drive.

i have a small favour, i have an acer 6930 that blue screened during a bios update, which in itself annoyed me, but i have been trying to reset/fix the biox in several different ways, and i would like to try yours but i cant find a DOS file for acer as they only give out the "WINPHLASH" and not the actual DOS files, was wonderinf if you knew where i could get it from thanks in advance stevesteve_9224 7.Apr.2013 05:23
