I have the _exact_ same hardware (except I have a 3c509 NIC instead, and the internal Adaptec card enabled), and tried the "noapic"-option just a few weeks ago, and thought that everything worked ok.. but then I the box froze, and "Unknown Interrupt" was the only thing on the console. This is the same error I get if I use kernel 2.0.36 (which at least boots, 2.1/2.2/2.3 did not). Have you had the same problem? Or did you try with 2.2 straight away? I've been trying to get my box to work with linux/smp for about 2 or 2 years now.. :). Btw, isn't it a real loss to boot with "noapic"? Isn't it much more efficient to let both cpu's handle interrupts? /scrm/ On Mon, 19 Jul 1999, Sunshine wrote: > > > > >Hi, > > if you are using lilo, try the noapic option.. for me to > >boot a test-kernel it would look like > > > >lilo: > > test-image noapic > > > > I found that 5 minutes after I sent this message... system boots up 2 > processors with the noapic cmdline. > > >see if that works... you can't ues the APIC unless your MB has > >the chip... > > > > > I have the chip.
