I've got a machine with an Abit SL6 w/ AGP/PCI/CNR onboard, but no ISA slots, and it still has an ISA to PCI bridge built in. Some of the devices still register with the kernel on the ISA bus, even though they are quite obviously connected to the PCI bus. I suspect that some of these devices may be tied to the ISA bus in the BIOS for arcane PC/AT reasons. I would be interested to know details though, if someone could spare a moment to give an over-the-top explanation of why this is true. Brandon D.
