They don't seem to spin up when stuck in a peecee (good old IBM
extensions i'm sure). However, they seem to be 2G.. so decent size.

Well, it's 'whacked' -- i poped the cylinder off of the switch part, and
turned the switch by hand (verified, it doesn't boot when it should be in
'Secure' mode). Still, not a drop out of either of the two serial ports.
I've checked them with a RatShack RS-232 led box, and everthing's 'wired
up' correctly it seems. Even tried two different null-modems with them.
Right now, the last thing that the LED display shows is '522'. (which just
stays on there, doesn't disappear)

I've got a 1-9: FC 2768 'POWER Gt3i Graphics Subsystem'. Any chance that
a PS/2 XGA card will work? I think I can get one of those, but I'm
doubting it'll work because of microcode...
