powerdown on Asus P2B-DS?

We have some old dual PII 400, Asus P2B-DS machines at home
running XP Pro. Is there any possible way to make these
power off on shutdown???

Currently shutting down the computer does not power it off,
it just gets to the "It is now safe to shut off your computer"
message.

I tried upgrading the BIOS on one machine to the
latest release (1013) but that didn't change the shutdown
behavior. This new BIOS apparently enables ACPI, on a new OS
install only, but we don't want to go that way since the ASUS site
notes that XP ACPI on dual P2B boards spins the second
CPU unless you mod the motherboard. Better to have to manually
power off than to lose the second CPU.

There are some indications that "NT APM/Legacy support"
may be present - at least this term shows up 2 places in the
registry. However the entry isn't evident in the device
manager even when "show hidden" checked. Moreover, some google
posts indicate that it doesn't work with SMP versions of XP.

Does XP have some sort of terminal shutdown script it runs
just prior to the "It is now safe to shutdown" message?

If so, anybody know what to put in it so that it pokes the right
bytes to the mobo/power supply so that it powers down???

Note that when these machines boot Knoppix from CD shutdown
in that OS does the expected powerdown at the end.
So the hardware can support a normal powerdown.

Thanks,

David Mathog
