Is there a DJGPP lib function equivalent to the Ms-Windows 
GetLogicalDrives one?

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/getlogicaldrives.asp

So far, I've found:

         r.x.ax = 0x1C00;
         r.x.dx = drive;
         __dpmi_int(0x21,&r);
         valid = (r.h.al != 0xFF);

to test a specific drive. But in my WinNT4.0 box it also tests for valid 
media in removable disk drives, wich is not what I want.

Is there a way to simply test if a drive is _installed_ in the machine?

TIA,
