Hi there, does anyone out there in net land know how you can find out from
DOS what the names of physical drives active in the system are? I haven't
found a DOS call for it, at least not obviously documented in the technical
reference manual. (ie. what I want to know is how I can find out that
drives a, b, and d exist and are real disks in the system or in the case
of a system with two partitions c and d on a hard disk,
and one floppy drive called a, I should get the names a, c, and d.)
NOTE: By names I don't mean I want a, c, and d, it is sufficient to get
a bit string with bits set for the drives that are actually attached.
It would be even nicer if I can get such info in a portable way.
-thanks in advance

I haven't I think this might work (I have not tried it): use function (_FUNCTION_, not interrupt) call Eh. It will do two things: make the drive selected in DL the current drive, and return the number of drives in AL. The way the drives are numbered is A=0, B=1, .... BUT: I believe if you have one physical drive (i.e. 0 being called A:), then you will also have 1 (B:), and DOS will do the prompting for switching of disks (i.e. Diskcopy a: b: with only one drive....) -- UseNet: {hplabs, seismo}!hao!isis!dragheb
