4.8.1. Does FreeBSD support power management on my laptop?

FreeBSD supports APM on certain machines. Further information can be found in apm(4).

FreeBSD also supports the ACPI features found in most modern hardware. Further information can be found in acpi(4). If a system supports both APM and ACPI, either can be used. We suggest you try both and choose the one that best fits your needs.

4.8.2. How do I disable ACPI?

Add following line

hint.acpi.0.disabled="1"
into your /boot/device.hints file.

4.8.3. Why does my Micron system hang at boot time?

Certain Micron motherboards have a non-conforming PCI BIOS implementation that causes grief when FreeBSD boots because PCI devices do not get configured at their reported addresses.

Disable the “Plug and Play Operating System” flag in the BIOS to work around this problem.

4.8.4. The boot floppy hangs on a system with an ASUS K7V motherboard. How do I fix this?

Go into the BIOS setup and disable the “boot virus protection”.

4.8.5. Why does my 3Com® PCI network card not work with my Micron computer?
