Standard SGI PROM Resolution is 1280x1024 @ 70Hz (maybe 75Hz),

That's a big "no", poops. 60hz for sure. And you can set the resolution lower from the prom if you need to. And the prom is more capable than a  BIOS. And it is pretty much unrelated to the installed operating system. And the mention of "a" CD iso is a little off - an Irix install takes several CDs.

Installing from CD is, admittedly, a pita. There's several other methods and many threads about that around here. Unless you are installing 6.3 ? That was specifically for O2 and did come on one disk. It worked okay, too, if you come across one.

The other thing about an O2 is, it will output straight vga graphics. So should be able to come up with a monitor pretty easily that will work. (As a newb to SGI, in Irixland there is graphics and there is video and they are not the same. That's one of the first clues to the secret handshake).

What you want to do, Mr OP Sir, is go straight to the horse's mouth and get the real info. Techpubs was wonderful. I believe jan-japp has mirrored the whole thing.

btw, the only one you really need to worry about power with is the bloody O2. But with that one yup, watch your p's and q's, the damn things are sensitive as a princess brought up in a convent. They can be pretty cool - you have an R10k one - but because they are so finicky they're my least favorite. But still, congrats.
