Those NMI and IRQ-party goes on at an rate of one event every two minutes. Will it wreck my system or can I ignore it? This appeared exactly when I replaced my old Ultra-Nonwide IBM-DCAS with two Ultra2-Wide DDRS-Drives and it disappears when I downgrade again. (btw, I know, U2W doesn`t boost my UW-system, but U2W costs less and maybe some day with my next sytem I can make use of it?) The System is a GigabyteDX Dual-PentiumMMX233-System with onboard aic7880 UltraWide. And an additional question: Can I use the termination of the U2W-DDRS-Drives to terminate my bus or is LVD/U2W-termination an evil thing at an SE/UW-bus? I already tested it both ways, but for now I use an extra SE/UW-terminator. -- Christian Brandt Life is short and in most cases it ends with death - Sir Sinclair To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
