They aren't full PCI nodes just yet in most hardware : designs (I've yet to see a floppy, keyboard or mouse on the pci bus, : but I'm sure people will tell me where I can find such beasts). I should have also added: Even though there are no ISA expansion slots on your machine, you still have an ISA bus living inside (unless it is a legacy free machine we keep hearing about, which I didn't think was on the market). The PC-99 standard (not to be confused with the Japanese PC-98 machines) states that you cannot have a ISA expansion slot, but a later clarification to the standard states clearly that you can still have ISA devices built into the mother board. In other words, No ISA slots doesn't necessarily mean that the machine doesn't have an ISA bus.
