Title: DVD will not work in DOS
Post by: alanh01 on October 13, 2019, 04:16:38 PM

How do I get MS-DOS to see DVD player? I have two drives. One with Windows 10, and the other drive with MS-DOS. My DOS drive is labeled drive E. At C prompted, I cannot change to E prompt. It would say "Invalid drive".

Simple answer is that you don't.
Instead of using an old version of MS-DOS, use a recent Windows system to see the DVD drive.
A workaround is to use another version of DOS that has the right drivers already installed. However, as I recall, they only work on a CD drive, not a DVD.

MSCDEX or Microsoft CD-ROM Extensions is a software program produced by Microsoft and included with MS-DOS 6.x[1] and certain versions of Windows to provide CD-ROM support.[2] Earlier versions of MSCDEX since 1986 were installable add-ons for MS-DOS 3.1 and higher.[

May I snuggest a quick workaround ?
Copy DVD files to USB stick and take it to the MS-DOS PC.

Generic CD-ROM drivers such as OAKCDROM.SYS work for DVD drives and you can in fact read most DVDs from within DOS.

Hi Alan,

You don't say what machine the dvd is in and what connection on the motherboard you are using if it is sata you will need gcdrom.sys from here http://help.fdos.org/en/hhstndrd/base/gcdrom.htm

Your harddrive will need a config.sys file and autoexec.bat file and have the lines added shown on that page.

Hi. This is a home-built machine. The DVD is an ASUS SATA. The motherboard is an ASUS Prime X370-PRO.
