Need help updating BIOS

Repo ManRepo Man Member Posts: 300
Hey guys/gals,

Wondering if someone could help with this. I'm running Win 7 Ultimate on my machine. When trying to update the BIOS through Windows it says I have to do it in 'Pure Dos Mode'. I've tried running it in safe mode w/ command prompt with the same message. Does a Windows 7 Boot disk exist that would help me do this or another utility?

    If it says it's for DOS, you have to use DOS, not Windows
    Check with the motherboard manufacturer, they may have a Windows utility to do the BIOS flash. Also, some motherboards have a utility built in that can get the new BIOS from a USB drive and do the update. If you can't find anything like that, you can create a DOS boot disk on a floppy, if you own one. If not, you can probably use the DOS environment available on the Ultimate Boot CD.

    Please never flash a BIOS from within the OS...I have seen several instances of a bad flash and once this happens it is very difficult to recover from a bad flash.

    The best way to flash is via a USB flash drive. Here is a link to get you started. Most modern system boards will have a BIOS update feature either at the start of POST or within the BIOS itself. If yours does not please visit the manufacture website for your system board and look for a bios flash utility (most of the time its some variant of AWDflash.exe). Here is a link to an e-how step-by-step guide on how to flash a BIOS. I would pay attention to steps 4-7 and substitute Floppy for USB Flash.

    Hope this helps, and good luck on the BIOS update. Incidentally with BIOS updates I usually follow the mantra..."If it aint broke. Don't Fix it."
