No, the "bus" I referred to was the SCSI or IDE bus. And IDE bus
supports two devices (called master and slave) while a SCSI bus
supports many more devices. It has nothing to do with PCI ID's.

Um, from your previous message, it seems that host numbering doesn't
change depending on BIOS settings.

So what exactly is happening? And what is the problem? I realise you
may find the naming a little confusing, but is there an actual
problem?
