In DOS execute this command to flash: afudos /i<New ROM filename> /o<Create backup of old version>
I.e afudos /i0401.rom /o0302.rom
To update with only a usb drive and firmware, just rename the rom-image to 701.rom, put it on a flash drive, reboot, and press ALT+F2 to load the updater. It's failsafe, during a bad flash it will boot into the flash utility and wait for a valid rom-image.
