What is the latency setting for the hard drive? It should be set higher than the cards. The article recommends setting the hard drive to have a latency of 0xb0 (176 dec). Also, the wiki links to an excellent article on the IBM Developer Works site <http://www-128.ibm.com/developerworks/library/l-hw2.html> which I highly recommend reading. That article gives more rational for the settings and gives good advice on IRQs (Interrupt Requests). Gus -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
