Hello,
A quick question, if I query device information on CD-ROM (int 21h,
AX=4409h), will I get that a CD-ROM drive is remote? (bit 12 = 1).
I am getting this under XP's ntvdm, and it sounds as a correct thing
(the filesystem is not FAT), but I would like to check in case someone
knows if this is correct).
Yes, as that call actually checks for the presence of the redirector,
not specifically for a CD-ROM drive, for that, you would have to test
for the existence of MSCDEX (or equivalent) via INT 2Fh, 150xh...
