x86-64 is compatable with x86-32 in 32-bit mode. one has to fiddle cr registers &c to turn on 64-bit mode, just like one has to fiddle cr registers &c to turn on 32-bit mode. (maybe efi does this for you. i don't know.) since the plan 9 pc kernel doesn't do any 64-bit mode stuff, this should not be the issue. the four-letter word is ELCR. 0x0000 -> all edge-triggered 8259 irqs. - erik
