That doesn't seem to work. I took out one SIMM and it complained on
bootup about needing a fully-populated bank. I can't remember the exact
wording, but it implied that you had to have at least 4 SIMMS installed.

Correct. There's nothing to port: it compiled out of the box.
And detected no errors at all. However, it only found 20 megs of free
memory in a 64 meg machine. I reckon the system is detecting 4 16 meg
SIMMs, of which 2 are broken, so I effectively only have 32 megs. That's
the only scenario that makes sense.

Amazing. SGI using standard parts?!? The horror! :)
