There seems to be no documentation for the IO APIC available anywhere, apart from the fact that it's got address space reserved for it. As far as intel is concerned, it appears as though the 82489DX practically never existed, and the vague reference "See your chipset documentation" for the IO APIC specs isn't much help either. Does that mean we need to get hold of a Neptune or the 430HX-formerly-known-as-Triton-II chipset manuals?? Or is this one of those areas that the BIOS is meant to program and the OS is to keep it's grubby hands off? Somebody once mentioned to me some unrelated manual that had a secion on the IO apic, but I've lost the mail and cannot remember who it was. It would be really, really nice if Intel could grab the apic section of one of their "chipset manuals" and stick it on their web server in .pdf format next to the pentium and pentium pro manuals. (non-encrypted pdf please, it's a royal pain having to go to a windows machine and print the damn thing from acrobat to a fake postscript printer to capture the .ps) Anybody got any friends inside Intel? :-) BTW, the MPSPEC 1.1 doc says: 82489DX Advanced Programmable Interrupt Controller (data book), Intel order number 290446. Let me know if you had better luck than I did... > -- > Steve Passe | powered by > smp@csn.net | FreeBSD Cheers, -Peter
