Many devices that were once on a visible, external, socketed ISA bus card have 
long since moved into ~bridge silicon, and most BIOS (and OS) expect some of the 
key ones to be there - be they emulated, downsized, integrated - whatever, and 
all at far higher speed than the 'real' ISA' bus ever could have reached.

It could be another ten years before that 'worldview' changes. If then.
