Yup, the VGX only runs IrisGL natively.. it might do OpenGL over IrisGL
though.

Nope, POWER series RAM is custom 200pin parts, you may be thinking of an
old personal iris 4D/20 which used 30 pin memory.

Nope that will not work because it is trying to boot off the SCSI HDD not
a CDROM. Older SGIs and I think Crimson is among them are really anal
about booting off the CDROM from ID#4 (this is very important, as other CD
Ids may give you trouble). Also in that hinv is telling you that is trying
to boot off the 2nd SCSI bus! MAke sure you are using the correct bus (I
blieve the IO3b has 2 buses).
