Still, keep an eye on it... Probably. The only real culprit for parity problems right now is the L2 cache of the processor, since we've got the version of the Pentium II that dosen't do ECC on it's L2 cache, and the memory in the machine is 36bit (yes, parity checking was/is enabled). Unfortunately when we were buying the machine we didn't know there were two different versions of the chip. steve -- // stephen clawson sclawson@cs.utah.edu // university of utah
