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...

Thanks, Aitor So I wrote a program to display the DX returned from that function call when pointed to a CD-ROM. To be fair, this is MSCDEX 2.25 on PC DOS 5.00.1. It said 0x1000. I think the answer is yes. -uso.___ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel

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).
