One gotcha with the ASUS boards are that they either: a) didn't wire the B-D PCI interrupts to anything or b) their BIOS doesn't understand how to program their interrupt routing. This is only a problem if you want to run something on the other side of a PCI-PCI bridge chip (like the SMC EtherPower 2). A properly implemented PCI card will attach the interrupt pin on each device on the subordinate bus to the main pins in sequence (dev1/pin A -> pin A, dev2/pin A -> pin B, etc...). In the case of the EtherPower2 pin A on the PCI slot is connected to the first ethernet device and pin B to the second. ASUS doesn't seem to understand what a PCI-PCI bridge is and why someone might want to use one. Their BIOS only detects and initializes the first PCI device on a subordinate bus (which is better than nothing!). After several months of fruitless bantering with ASUS I gave up and switched to Tyan (1462) for new machines. Having said that, as long as you never want to use anything with a PCI-PCI bridge ASUS makes good motherboards. -Eric Varsanyi Berkeley Software Design Inc.
