I could get a 1542C and a 2GB SCSI for a trial > with my GA586DX..... I should have looked CLOSER at the dmesg output you sent me. Since you are using the same board as I am, I just jumped to the conclusion that you were using a SCSI disk, pass me the pointy hat! from your dmesg: > FreeBSD 2.2-961014-SNAP #22: Sun Nov 17 16:03:37 1996 > ... > ahc0 <Adaptec aic7880 Ultra SCSI host adapter> rev 0 int a irq 9 on pci0:12 > ahc0: aic7880 Unsupported adapter type. Ignoring I *think* ^^^^^^^^^^^^^^^^^^^^^^^^ this is because its OFF in BIOS earlier boards came with this chip as an option, but I think this says your board actually has it, but its turned off in the BIOS. The BIOS may also be "smart" enough to see that there are no SCSI disks attached and turn it off on its own, so just turning it on in the BIOS may not be enough to make this message go away. It might also be a result of using the 961014 SNAP, I don't remember when support for the 7880 was added, but it definately IS supported in the SMP-current kernel. > wdc0 at 0x1f0-0x1f7 irq 14 on isa > wdc0: unit 0 (wd0): <ST32140A> > wd0: 2015MB (4127760 sectors), 4095 cyls, 16 heads, 63 S/T, 512 B/S So this is what you are actually trying to boot off of? So confirm you have the SCSI support on your motherboard and then all you need is a SCSI disk. If this is your only problem then the current code, including the init_main.c commited today, should work for you with without "options APIC_IO". This is the first thing to verify. If you can run that, then we are down to 1 reported failing machine (excluding the IDE related failures). This 1 machine is a 4 CPU motherboard, and also might now run with todays init_main.c. -- Steve Passe | powered by smp@csn.net | FreeBSD
