Create a working directory:
mkdir biosupdate && cd biosupdate
Download the latest BIOS image from your vendors site and put it into the newly created biosupdate directory.
The Award BIOS is used on a lot of motherboards, but please check twice if this is the case on your machine.
wget ftp://ftp.shuttle.com/BIOS/utility/awdflash.zip
Download the FreeDOS boot image:
wget http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/fdboot.img
Now we create a directoy to loop mount the FreeDOS boot image, remove one unnecessary file and copy the flash utility and the BIOS image into that directory. Then we unmount the image and delete the temporary directory. The result is a new boot image:
mkdir tmp
mount -t vfat -o loop fdboot.img tmp
rm tmp/fdconfig.sys
cp awdflash.EXE <YOUR_BIOS_IMAGE> tmp # Replace <YOUR_BIOS_IMAGE> with whatever file you downloaded in the very first step
umount tmp
rm -r tmp
Now we have to create an ISO image:
mkdir isoimage
cp fdboot.img isoimage
mkisofs -r -b fdboot.img -c boot.cat -o biosupdate.iso isoimage
If your system is configured correctly, you can burn the image with the following command to a blank CD:
cdrecord biosupdate.iso
Boot the CD and if all went well, you can enter awdflash
