[OpenBIOS] IO-APIC

Tue Jun 27 21:45:54 CEST 2000

  I don't think our IO-APIC is enabled..  We tell it to set its ID to 2,
but it continues to think its ID is F.  Here is the kernel panic:

ENABLING IO-APIC IRQs.
...changing IO-APIC physical APIC ID to 2 ...
Kernel panic: could not set ID!.
.
In idle task - not syncing.
APIC error interrupt on CPU#0, should never happen..
... APIC ESR0: 00000000.
... APIC ESR1: 00000040.
... bit 6: Received Illegal Vector

Does anyone know how to setup the IO-APIC correctly and/or know where I
can find this information (Maciej, you wrote io_apic.c, right?)?
Any help would be greatly appreciated.  Thanks.
