Last week I booted Plan 9 on one of Ron Minnich's dual-core dual-processor AMD systems without trouble. It was an Iwill DK8-HTX motherboard with an MPS 1.4 table supplied by the BIOS. Ron had less success booting Redhat on it, the kernel seg faulted.
It's getting harder to ignore bloat like API, though. --jim On Mon Feb 20 15:41:17 EST 2006, [EMAIL PROTECTED] wrote: > On 2/11/06, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > > (BTW, can plan 9 actually use multi-core processors?) > > > > In principle, yes, since they are just shared-memory multiprocessors > > packaged more compactly than previously. > > > > Having said that, I don't know if Intel and AMD did the obvious thing > > and just populated the MP table appropriately or whether they felt > > compelled to gratuitously do things differently because the word > > `core' is spelled differently than the word `processor', thus > > necessitating at least minor kernel changes.
