4.7.1. What other devices does FreeBSD support?

See the Handbook for the list of other devices supported.

4.7.2. Does FreeBSD support power management on my laptop?

FreeBSD 4.X and later support APM on certain machines. Further information can be found in apm(4).

FreeBSD 5.X and later support 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.

4.7.3. How do I disable ACPI?

Add following line

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

4.7.4. 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.

4.7.5. 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”.

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

Certain Micron motherboards have a non-conforming PCI BIOS implementation that does not configure PCI devices at the addresses reported. This causes grief when FreeBSD boots.

To work around this problem, disable the “Plug and Play Operating System” flag in the BIOS.

4.7.7. My PCMCIA card does not work. I have a message: “cbb0: unsupported card type detected.” What can I do?

You can try to use the original OLDCARD implementation. Edit your kernel configuration file and remove the following lines:

device cbb
device pccard
device cardbus
Then add:
device pcic
device card 1
Rebuild and install the new kernel as described in Configuring the FreeBSD Kernel.
