The "***EXEC PARITY ERROR STOP***" message is when you get a parity error in the memory where the kernel resides. RSX can deal with memory errors in other parts of the memory, by just making that memory unavailable for programs to use. But it cannot do this with the parts that the kernel use, so then it panics instead. Ahh. Damn. I'd be okay if the only other memory board I had spare wasn't PMI. There's that 16K board...I could adjust the memory offsets. First bugcheck is essentially an illegal instruction in kernel mode. (Error code=110 is illegal instruction, while facility=300 means the executive.) Ahh. Johnny -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
