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. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
