Well I assume my bois supports it as it tells me it's an M2
At startup above memory countup it says 'M2-MMS-PR166+'
And in the info screen just after bois check has finished it has
CPU-Type: M2-MMX
Co-Processor: Installed
CPU Clock: P166+

Thats the panic message. I'm not sure what you ment by stack traceback (give me
the commands to execute in DDB and I'll print it out..
Other info I found..
At time of Panic:
cyrixreg:
CCR0 = 2 CCR1 = 82 CCR2 = 80 CCR3 = 0 CR0 = 80000011
