I visited the ASUS site an noticed that there were 5 (NOT 4) slots on this board and thought perhaps that that was done by making 2 PCI busses on the motherboard proper. Thus I wasn't sure if you were seeing PCI0 and PCI1 because of this fact, or because the BIOS was smart enough to see the PCI bridge on the 3940. Since both ahc and ed0 are in the 1st 4 slots, and presumably the MP table/dmesg shows them on pci1 and pci0, respectively, it appears to be the result of a BIOS 'doing the good thing'! This is re-enforced by the MP table for the same ASUS board owned by someone else that has no bridge cards and shows only 1 PCI bus (MP table database entry #5). -- Steve Passe | powered by smp@csn.net | FreeBSD
