Why did my laptop fail to correctly probe PC cards?

This problem is common on laptops that boot more than one operating system. Some non-BSD operating systems leave PC card hardware in an inconsistent state. pccardd will detect the card as ``"(null)""(null)"'' instead of its actual model.

You must remove all power from the PC card slot to fully reset the hardware. Completely power off the laptop. (Don't suspend it, don't let it go into standby; the power needs to be completely off.) Wait a few moments, and reboot. Your PC card should work now.

Some laptop hardware lies when it claims to be off. If the above does not work shut down, remove the battery, wait a moment, replace the battery, and reboot.
