Here is a question for the experienced I/O programmer...

How do I find out the type of physical devices associated with a logical
device without using IOCTC Int 21H 0x44H subfunctions 0x60 and 0x40?
The general block device interface doesn't efficiently tell me about the
type of device I'm using...   

Basically, I'm working on a format program and I need to be able to
recognize all floppy devices and their type...  also, the procedure 
needs to be compatible with MS-DOS 3.1, since that's what Windows requires.
