You may be able to get this information from INT 13h
service 8.  This returns the number of heads, sectors,
and tracks for a given drive.  From this information
you can determine what type of drive is installed.
I don't remember exactly how to use this call but
you should be able to find documentation on it somewhere.

To determine the drive try use

Tracks	Sectors	Type
------	-------	----
80	18	3 1/2 (1.44MB)
80	15	5 1/4 (1.2 MB)
80	9	3 1/2 (720 KB)
40	9	5 1/4 (360 KB)

Hope this help.
