Yep, fc492 is in the BIOS. You shouldn't be getting this panic with ACPI as we don't call the BIOS to route interrupts for the ACPI case. You are probably a victim of whatever broke BIOS32 calls in 5.x (all the way back to 5.0) that causes panics in the !ACPI PnP BIOS probe on 845 and 865-based motherboards. -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.orgReceived on Mon Mar 01 2004 - 12:38:12 UTC
