mscdex.exe is not the driver for the cd-rom it is used in the autoexec.bat file to give the cd-rom a drive letter D: example. The driver statment has to be in the config.sys file and point to the dir where the driver file is stored. Example Device=C:\mtm\MTMCDROM.sys /D:000nt
This line will very depending on the brand of CDrom you have. These statments are needed to make a cdrom work in dos. If it is an older CDrom and windows95/98 can't find it they will be needed also.

If you have the Dos installation disk that came with the CD-Rom install it if the boot disk you made does not contain the driver files for the CD-Rom. This should allow the CD-rom to be seen. If you can find a setup disk for windows 98 if that is what you are installing this will work too. Once windows has installed it will rem the dos statments in autoexec.bat and config.sys to keep the drive from running in dos mode.
Hope this helps

I have a compaq presario 7478.
The Mscdex.exe file is in: C:\Windows\Command.

In the Dosstart.bat file I have the following line: LH C:\WINDOWS\COMMAND\MSCDEX.EXE /D:IDECD001 /M:12.

Hope this helps.

Not sure why you would want this since Win95, Win98 and Win2000 all use a standard driver and would handle the CD Rom if all the setup, ie. cable, bios, power are set correctly.

But in any case there are two entries that are required.

The first is in the config.sys and looks like this:
LASTDRIVE=L
FILES=20
BUFFERS=20
DEVICE=C:\(CDdriverhere) /D:CD001

If you place the CD driver in the root C: then you would only need to enter the driver name, make sure you don't use parenthesis.
If you place the CD driver in say a directory of CDROM then you would change the line to read
C:\CDROM\CDDRIVER.XXX /D CD001

If you are putting this on a boot disk then it would be best to have the exe, the drivers and such on A: and adustthe path to reflect A: not C:

Hope this helps, if not post a comment and give additional information, particularly the Operating System that you are using.

sorry, let me be more specific. i formatted 40GB hard drive. have boot disc. turned system on, put 98 disk in, tried to change to cd drive, D or E. no valid drive selected. I have mscdex in root directory. shouldn't this be useful to detect cdrom driver and install cdrom? how do i get system (home built) to recognise cdrom.

I take it that the BIOS has been set to boot from CD at startup? Also if u try using the option to boot with CD ROM support it shud work. If all fails then u need a Win 98 Setup disk as this will remember the the rem statement in autoexec.
