Dr. Dave, did you ever have a chance to take a pic of that dud 350 module which you found?
Are you still here? Or can someone else with a working 350 mod supply a pic showing the
I've just completed five R12K/300 mods for O2 (ie. moving 300 cores into 250 modules, moving
resistors to give 300MHz), but alas the 6th mod did not work (red light). Digging around, I found
an R10K/225 module. Moving the 300 core over gave a module which boots ok to the PROM,
but an IRIX boot fails just about when it starts to mount file systems (screen goes black, then after
a pause the display changes to the prompt saying it's ok to turn off the system). I can boot into
single user mode, but there's nothing in the SYSLOG.
I tried changing the crystal speed to make the CPU run at 250 instead, but the behaviour persists.
Shows up ok in hinv as R12K/250. As I type I'm running the ide tests (so far it's passed icache1,
icache2, dcache1, fpu, and scache1 to scache3; currently running scache4).
Any ideas anyone?
