It's not necessarily just because of what the BIOS does. I am of the belief that the PCI card only works under the CardBus programming model. The reason should be obvious: the IRQ lines that the PC-Card interface needs aren't available on the PCI connector. When that chip is used in a laptop, it's connected directly to the PIIX so that it can get the full ISA functionality it needs in order to implement the Intel PCIC programming model. -GAWollman -- Garrett A.
