IRIS hardware strangeness

[paulf]

I'm working on an IRIS 2400T, with a 19" 30Hz monitor, MD controller, and
2 megs of memory.  It boots mdfex just fine, and downloads the disk, but
when I try to boot Irix, it load and jumps, and then the screen goes
blank and.... nothing happens.  I've tried using a noninterlaced monitor,
but the funny thing is, that the IRIS still thinks it's interlaced, even
when I change the dipswitch settings.  Another strangeness is that the CPU
card has three EPROMS instead of four, but still appears fine.

Any ideas out there?
