It's been a while but the last time I did this, I copied the update program and firmware update to a USB drive or the on board hard drive and booted into freedos and ran it with no problems. If your system is BIOS it should work fine. If your system is UEFI all bets are off as I haven't worked on any of those yet.
So the USB flash drive and HDDs were visible in the normal manner once booted into FreeDOS? That makes sense... I was thinking they were not, so that such things could be manipulated, but I guess you just don't have to use them for anything that can't be force-closed. DOS and USB? BIOS exposing it as a HDD I suppose, so it's at the mercy of the BIOS.
Re UEFI: my bios boot stuff is nuts, which is why I want to update it. Boot entries don't behave sanely or consistently. The previous copy of the motherboard, returned for other reasons, was fine with that so I'm hoping it's just the firmware.
