Is there a reliable way to figure out how many and
preferrably which (e.g. A:, C:, D:) logical disk drives
are available in a DOS system? DOS function 10h is not
satisfactory, since it simply returns the LASTDRIVE=
value. If I set LASTDRIVE=Z in my config.sys file,
function 10h returns 26, but all I have is A: and C:.
Again, I am talking about _logical_ drives, including
RAMdisks and SUBST'd drives, so BIOS INT 11h won't do either.
Solutions in C or ASM, and hints are very much
appreciated.
Thanks in advance,
  Erik
