HOWTO - USB Flash BIOS Key Method
BIOS must be able to boot to USB bootable devices. Not all MBs have BIOS versions with USB as a bootable option. Double check your Manual if you are unsure if this option is supported.
- 1. Make the USB Flash key bootable (you need a DOS Floppy-Disc to do this, make one on any other PC and store the files than on your USB)
- 2. Insure that you have the command.com, IO.sys and MSDOS.sys files on the USB key so that it will be bootable. (usually you get this files when you make the Floppy-Disc, so you have to see to get his files somehow)
- 3. Place the unzipped batch files (batch file, flash utility, bios file and .txt file) on the USB key. (this are the BIOS version files that you Downloaded)
- 4. Make sure that the USB Flash Key is at the top of the boot order in your bios so that when the motherboard is turned on it will immediately boot to the USB Flash Key and boot cleanly to an A: prompt. (press something like F11 to come in in the boot order - take a look in your Manual, it's the easyest way and the Drive letter is no problem any more)
- 5. Simply type in flash at the A: prompt and the rest will be handled by the batch file itself. (or remmember the Driver letter your USB is connected and type that)
- 6. Clear the CMOS. Reboot system and the flashed version of the BIOS should now be present on your screen. (I described this in many other posts here)
The only right method to Flash BIOS is still with the old good Floppy and for shure it will stay so for the next few years. To Flash from USB or CD is OK, but much more complicated and I recomand this as some kind of last solution.
If somebody says Flash from Windows, sorry but he doesn't know what he is saying, but I will forgive him
