It's plain old DOS usually - booted from a floppy to the flashing A
drive prompt so you can easily fashion a DOS boot floppy for each card you
may wish to flash. Flashing can be done with Windows running with apps like
WinFlash etc but the problem is that the Windows flashing apps are unlikely
to recognise or use a mac rom. It's also worth pointing out that many Radeon
cards are flash locked to access only 64K of the rom and full mac roms are
128K. So reduced roms or high soldering skills are required - reducing is
done by removing more than half of the mac rom data. Unlocking via soldering
requires moving very very small resistors. The rom chip onboard the card may
also be only 64K but they are quite easy to replace with 128K chip. Cards
flashed with a reduced mac rom should then be flashed again in a mac using
Graphiccelerator 1.3.3a utility and the full mac rom as it ignores the 64K
lock. All great fun....
