BRETT_GLASS@ccgate.infoworld.com stands accused of saying: > > How good is the PCMCIA support in FreeBSD? Will I be able to swap cards? PCC support is actually getting along pretty well. You can certainly swap cards, and with certain caveats (routes, NFS mounts, open serial ports) you'll be just fine. > Is APM supported?

APM is supported, although many laptop APM implementations make a lot of assumptions. I can enable APM and lid-suspend my Sharp, but trying to talk to the APM interface causes it to trap (the fault address is in the BIOS, so I don't think it's the APM driver's fault per se.) The system syncs on suspend, and snaps the clock when it resumes, so that missed cron jobs are just lost. Filesystems aren't marked clean, as that requires an unmount. Some PCC's require reinitialisation coming out of a suspend (and removing a card while suspended can cause grief), and support for that is in place but not implemented. > Finally, there doesn't appear to be a driver for my 3C562 Modem/Ethernet > combo card.
