I am trying to setup a CD ROM drive on my computer.I can load the software that is provided with the CD ROM, i.e. setup disk and it says I have successfully loaded this.When I reboot the PC the computer also recognises that the CD ROM is there,but when I go into Win 3.1,the system does not see that the CD ROM is available i.e A drive and C drive are recognised,but not the CD ROM drive.Can anyone out there help me?

Win 3.x is actually a DOS OS, and requires correct AUTOEXEC.BAT & CONFIG.SYS Files in the Root Directory of the C-Drive.

For the CD ROM, you need something like the following in CONFIG.SYS (put it near or at the end).

DEVICE=C:\CD1200.SYS /D:CD003

C:\CD1200.SYS is the path & file name of a CD ROM Device driver. Yours might have some other name. This one expects a PCI IDE device. If need be, I could send it to you, but I have no idea if it would work on your system (chances are that it would).

You need the following in AUTOEXEC.BAT

C:\MSCDEX.EXE /D:CD003 /V /M:15 /L:X

C:\MSCDEX.EXE is the path and file name of a TSR program (Terminate & stay resident), which responds to CD interrupts. /D:CD003 is used to link to the Device Driver. I do not know what /V & /M mean, but you could check it out in a DOS Manual (I could look it up if you want me to). /L:X specifies that X is to be used as the Drive letter for the CD (This can be anything beyond your last Hard Drive letter). MSCDEX.EXE is usually supplied with DOS, but the device driver is usually from a manufacturer of the CD reader. I could send you a copy of MSCDEX.EXE, but it is unlikely to work if your version of DOS is different than mine.

BTW: AUTOEXEC.BAT should have something like LASTDRIVE=Z, and the Drive letter for the CD must be equal to or less than the Last Drive specified.

The above is all you need for the CD, but the above control files might need other jargon to make your system run well. There are incantations to put all sorts of stuff in memory beyond the first 1MB. DOS has trouble using more than the first 640K of memory, and needs some help.

I could send yo copies of some sample control files.
