	Did this error start when you switched to using a monochrome
monitor or did it just spontaneously happen? If it just happened, you
might have loose/dirty or a bad SRAM chip on the card. You might try
swapping board 1 with board 3 and see if you get a blue screen error
(Ha!) and report back. If it started happening when you switched to a mono
monitor, then there probably isn't anything wrong with the card, and no,
you can't make the PROM ignore a default test failure. You may however be
able to trick the card into thinking that the red signal is attached by
terminating it, but I don't know the innards of the Bt RAMDACS or if that
is even the real problem.
