ACPI and APM are two standards for power management and configuration.
The kernel developers tend to be rather rude about the design, and very
rude about how it's implemented in too many motherboards.
Only one such system can be run, and you have to reboot to change it.
By default, ACPI will run if your BIOS is from 2001 or later. Otherwise
APM will run (although it doesn't do much in SMP mode: APM isn't well
defined when there are two processors about).
On the kernel command line in /boot/grub/grub.conf: e.g.
kernel /boot/vmlinuz-2.6.7-1.478smp ro root=LABEL=/ rhgb quiet
you can add the parameter acpi=off to force ACPI off, acpi=force to
force it on (useful if you have an older SMP box and you want it to be
able to turn itself off, for example), or apm=off to force APM off.
Yes, you can have both of them off.
HTH,
James.
