My IP21 (Dual R8000 Onyx) is giving me grief
As I understand, SGI made two families of R8000 systems : IP26 (Power Indigo2) and IP21 (Power Challenge/Onyx), and both are supported up to IRIX 6.5.22
Except 6.5.22, and probably 6.5.21 are broken on IP26 . Maybe even as far back as 6.5.18. I have reason to believe IP21 has similar problems .
I've had 6.5.14 running on it at some point and it worked. My IP26 runs IRIX 6.2 and is not affected.
So, my questions to those with R8000 systems: what OS are you running on them? Which is the last unaffected IRIX release? Is this issue fixed by a patch (that I would have to install when I install the OS)? Or maybe it's possible to run 6.5.22, as long as I use rqs binaries from an earlier, unaffected release?

Now this is a deep dark secret, so everybody keep it quiet
It turns out that when reset, the WD33C93 defaults to a SCSI ID of 0, and it was simpler to leave it that way... -- Dave Olson, in comp.sys.sgi

In the museum : almost every MIPS/IRIX system.
Wanted : GM1 board for Professional Series GT graphics (030-0076-003, 030-0076-004)
