You are kidding. I put junk in the CVS server?
I guess he still need some time to figure out how to modify his mptable.c.

I've been stuck at this problem for a while. My linuxbios boots a NON-SMP kernel ok but not the SMP one. The SMP kernel gets loaded and run. When it tries to access an IDE drive, an IDE command timed out before anything returns(kernel messages). My I/O APIC settings correspond to the MP table.
All ISA devices are mapped to the I/O IOAPIC at 0xFEC00000. But where do we set this I/O APIC up? How does it know to route the IRQs to the local APIC?
Linux looks at the mptable.
Another question is, does linuxbios setup the local APIC as Virtual Wire mode that via I/O APIC?
Usually we simply setup the local apic in virtual wire mode.
My board is similar to Tyan/s2735, does anyone get this booted with a SMP linux before??
Good question.

No. I just could not remember if it was a recent or an ancient board. If it was an ancient board in the v2 tree I could see problems.

I understand Linux looks at the mptable and looks for IOAPIC entries.
I meant where in Linuxbios do we configure the IOAPIC at FEC00000 or we don't have to do anything? Linuxbios DOES do something to configure the IOAPICs of P64H2.
Thank you, gin

Didn't mean to be rude. I just want to be sure.
