statvfs() will give you some of the information for a filesystem.

There is no "fat" in unix, only different filesystems.

Getting information directly from the BIOS is a hardware specific thing - since you seem to be on a PC try searching:

www.tldp.org for information on filesystems and the BIOS interface (sometimes called a HAL).
