Could the slow-down be in the driver for the PCI Ether card??? Just wondering; I am just surprized that a 32-bit (and twice as expensive) ethernet card runs *half* the speed of a 16-bit card; both cards are made by Linksys. Also, swapping out the PCI Ether card got rid of many "stray irq 15" messages appearing during boot-up; is there a connection? >How-To-Repeat: >Fix: >Audit-Trail: >Unformatted:
