I have a program that needs to know how many disk drives [block devices] are 
present on an IBM PC / compatible.  I know that interrupt 11h (equipment 
check) will tell me about diskette drives, but I also need to find out about 
fixed diskes (which may be partitioned into more than one logical device) 
and other device drivers which are loaded through config.sys (e.g. Iomega 
Bernoulle boxes).  

Does anyone know of a way to check for the presence of block devices without
either asking the user (who in this case will probably not know the answer),
or making calls to DOS that will put strange error messages on the screen.
