Tom's page talks > about trying your luck there. no, bios doesn't give that level of control. you get 2 settings: Auto-config: 60/70ns or 60ns, I use 60ns (with 60ns non-EDO memory) Fastest 60ns DRAM timing: NO/YES, I have to use NO, YES gives parity ERRORs and/or panics. > Things I don't like: > > bios won't let me assign specific INTs to PCI slots. this would be nice for my development efforts for the APIC... > bios thinks my stealth64 card is occupying a PCI INT. potentually wastes an INT, I haven't figured out the details yet, I just jockey around the "ISA reserved IRQs" in the BIOS and put it in the "right" slot till it causes me no harm: vga0 rev 0 int a irq 9 on pci0:11 [ at this point ahc0 is also on irq 9, but SMP kernel uses direct APIC IRQ19: ] ahc0 rev 0 int a irq 19 on pci0:12 Freeing (NOT implimented) irq 9 for ISA cards. -- Steve Passe | powered by smp@csn.net | FreeBSD -----BEGIN PGP PUBLIC KEY BLOCK----- Version: 2.6.2 mQCNAzHe7tEAAAEEAM274wAEEdP+grIrV6UtBt54FB5ufifFRA5ujzflrvlF8aoE 04it5BsUPFi3jJLfvOQeydbegexspPXL6kUejYt2OeptHuroIVW5+y2M2naTwqtX WVGeBP6s2q/fPPAS+g+sNZCpVBTbuinKa/C4Q6HJ++M9AyzIq5EuvO0a8Rr9AAUR tBlTdGV2ZSBQYXNzZSA8c21wQGNzbi5uZXQ+ =ds99 -----END PGP PUBLIC KEY BLOCK-----
