I like this LAPIC change a lot. Actually I like APICs a lot. They may not give you 'real' vectored hardware interrupts a la SPARC and PowerPC, but at least it comes a bit closer. It would be nice to be doing APIC on uniprocessor systems a bit further down the line, but that's for the wishlist -- the 8259s are not going away just yet. Regards, BMS
