Does selecting the incorrect HAL affect performance at all?

Windows has always detected my PC as a "Standard PC"... I'm going to re-install windows and now tha I know you can change, I'm going to tell it to use ACPI.

Is there any advantage to using the correct one? I've never had any problems using standard PC .

It really just affects IRQ routing, ACPI would be preferred but using standard PIC won't hurt anything. Also it'll force you use APM for power management instead of ACPI, if your box does any PM and if you care.

In the scenario your describing no, however using the multiproc hal on a single proc system is very very slightly slower since certain syncronization primitives (like spin locks) don't need to actually do anything on the single proc hal but have to be implemented on the multi-proc one.
