During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360 KB type is 40 tracks while 720 KB, 1.2 MB, and 1.44 MB are all 80 tracks.

Enabled	BIOS searches the floppy drive to determine if it is 40 or 80
	tracks. Note that BIOS cannot differentiate 720 KB, 1.2 MB,
	and 1.44 MB type drives as they are all 80 tracks.
Disabled	BIOS will not search for the floppy drive type by track
	number. Note that there will not be any warning message if
	the drive installed is 360 KB.
