RE: IBM / FreeBSD Install problem

Thanks all,

We will look into the code editting and see what we can get
however we are on an very short time frame so may not be able to
slot it in before a maintenance slot where we need to be able to drop in
the box 'seamlessly' .....

But I have noted the proposed fix provided on these lists into the red
book!

If you can either install without ACPI, or remove two of the CPUs
during installation, this should be fairly easy to fix: change the
definition of NLAPICS in
/usr/src/sys/{amd64,i386}/acpica/madt.c and
rebuild your kernel, then boot with ACPI enabled and report back to
us.

I suggested that in email too, but looking closer, I think the MAXCPU
needs to be increased because the cpu number uses the
apic_id. Or could
that be changed with a logical CPU to APIC ID lookup?

Isn't the APIC IDs programmable? not that I am suggesting that, I
can think of headaches of all the places (like interrupt tables)
where it needs to be changed, not to mention the worry that the
lower APIC IDs were assigned to IOAPICs.
