PowerPC doesn't have any such concept; access to ISA PIO is done by having the bridge translate a particular range of MMIO accesses as PIO. I'm no expert, but I don't know of any mainstream processor other than x86 that supports PIO. -Hollis ------------------------------------------------------------------------- Take Surveys.
