So I've got an older board here, slot 1.
It will boot with a PII 350 (uh klamath?) various celerons (medocino), etc.
I have a post card, and on this board, during the boot sequence, it will start at 0xC0, then go through C1 / C2/ etc. during the boot sequence.
So I figured... get a PIII 600, the fastest CPU that this board *should* support. (All PII boards should support non-coppermine PIIIs AFAIK, as they're... basically PIIs. right?)
When I plug in a PIII cumine 1GHz, the post card shows the board halting at "C0", which makes sense as it is unsupported.
But.. when I plug in the PIII 600 katmai, the post card just shows "0", and nothing happens at all.
Now... I believe all the CPUs that it did boot with are 2.0V. The particular PIII 600 katmai I have is 2.05V -> Do you think the non-boot issue is being caused by this confusing the VRM?
I think I'll look into the pinouts and try to trick the board into thinking it's a 2.0V processor, but was just wondering if anyone remembers having a similar issue in the past.
