There are two cards in the 5-PCI slot MotherBoard (NO bridge chips). Note that they are both on PCI bus #0. The problem is that there are 5 PCI slots, 4 PCI/ISA redirection registers, and 4 MP table entries. Yes, it is a problem with the Tyan MB that it doesn't have all the PCI slots in the table. Kevin
