# I tried it on an old dual PII system. I build a kernel from

Just a shot in the dark, but:

- do you have 'cpu* at ...'?
- would acpi* at mainbus? work better?
- is acpi supposed to attach to the mainbus rather than to an ioapic
  [perhaps I'm saying that backwards]?

NOTE:  I don't know a lot, but I figured it might help.

# The kernel boot fines, but the kernel finds only one CPU.
