Comment 84 for bug 719620

@Daniel: Often times the Windows-only BIOS updates are self-extracting zip files. You can try running unzip on the file to see if that is the case. If it is you can inspect the contents to see if there's something useful in there. Sometimes you'll find a DOS executable that you can run on a FreeDOS USB stick to update the BIOS. For one Toshiba machine I found an iso image that could be burned to a CD for updating the BIOS. If you don't have an optical drive you might be able to copy the contents of the iso image to a USB stick and use syslinux to make the stick bootable (I think this is what I ultimately ended up doing).
