Thanks for the info. Let me understand the situation better: local APIC
IDs are preassigned by the firmware based on their "socket address" and
the socket where the lowest numbered quad would be is empty.
Nevertheless the firmware sets the destination ID of the ExtINTA interrupt
in the I/O APIC to 0 rather than the ID of the bootstrap CPU. Is that
correct?
But it would mean the Virtual Wire interrupt delivery would not work, or
is the I/O APIC setup redundant and the local APIC of the bootstrap CPU is
set up for ExtINTA delivery as well?
