No. The problem Intel boxes do use Phoenix BIOS. His box is the exact problem model. It requires the use of IOAPIC support for UP or SMP in order to work properly. If 2.4.8 and 2.4.9 both work correctly now *without* the use of UP-IOAPIC and without SMP, then that means in 2.4.8 there must have been added a DMI scan whitelist entry that makes this motherboard do something sane (like never trying to assign interrupts or enabling UP-IOAPIC even if it isn't the default). -- Doug Ledford http://people.redhat.com/dledford Please check my web site for aic7xxx updates/answers before e-mailing me about problems
