I remember reading somewhere that AMD insisted in the board guidelines
that all boards that I know of are PC2001 (or so) compliant. PC2001
compliance means:
1) MUST have acpi 2.0,
2) MUST have local apic/io apic
3) MUST NOT have isa slots,
etc.
The 'isa' devices that we support are not actually isa electrically.
There are various low-pin-count busses on board that things like the
super-io chips, flash etc are connected to. They're flat address space
just like isa - no enumeration. In software they behave like their isa
counterparts, but elecrically and physically, there is no 'isa'
hardware on any of these boards.
And, good riddance in general.
