The NCR runs it's firmware from the host memory, try cranking the PCI latency timer down for the NCR card and see if that helps. (This is in the PCI bios setup screen). Depending on motherboards (I happen to know what ``Triton'' board Jim just tried this in) there maybe 1 setting for all slots, or each slot may have it's own setting. Either way, crank it down to about 40 (default should be 80). -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
