MSCDEX.EXE for installing new CD ROM
Hello--
Trying to install a new CD-ROM on an old Win 3.1 system (P-90 Compaq Presario) so that I can install Win 98. The old CD-ROM was broken, so I got a new one and installed it. When trying to load the drivers off the supplied floppy, I got a message that I needed MSCDEX.EXE version 2.22 or above to continue. I understand that DOS extension is needed to interface the computer with the new CD-ROM drive. I think this computer has an older version of DOS.
First question: where do I get this executable? And second question: how do I install it from DOS, assuming I get the executable on a floppy (sorry, I don't recall the "COPY" commands from DOS!)
Thank you in advance for any help you can give me.
