The Ethernet card is generating 400-500 interrupts/sec, and the IDE drive is generating 500-600 per second most of the time, occasionaly peaking at 900. > If your Ether card is ISA, that says it all right there. I was afraid of that. Guess it's time to travel to the coloc site again and replace the E-net card. Thanks for the insights.
