I have a computer that I just loaded with DOS 6.22 because my control software requires it. Now I can't access my Cd-Rom, I get an invalid drive error when I try. I know it works because I just had Windows 98 on it before I reformatted it and loaded it with DOS and the Cd-Rom worked fine. I could use any advice you may have. Thanks-Robbie
does the config.sys and autoexec.bat have any drivers loaded?
You need the CDROM driver in config.sys file:
DEVICE=CDROM.SYS .... or something similar. If not available, search the net for generic driver.
Then you need the CDROM dos extension line in AUTOEXEC.BAT:
MSCDEX.EXE .... or something along this line.
Or just go to http://www.bootdisk.com and find a suitable boot disk there :)
Hey guys,
Thanks for your replies. Im not to experienced with DOS. Can I edit the config.sys and AUTOEXEC.BAT file and add those lines or do I need to do something more, Thanks-Robbie
You can just edit them and type in the lines.
Off course making sure the additional files are there :) Just adding the statements without the actual files won't change anything (except given error messages)
If I do need the files, Do I just find them on the internet and copy them to the hard drive. Thanks for all your quick answers.
bootdisk.com will have them. If I remember correctly there image contains everything you will need.Quote:

I tried adding the lines and I got the error message saying I needed the driver. I went to bootdisk.com and downloaded the bootdisk for DOS 6.22 and wrote it to a floppy. I was wondering would all I have to do is copy MSCDEX.EXE file to the hard drive or do I have to do something else? Thanks- Robbie
Copy MSCDEX.com to the hard drive or indicate where it is with the Path command.
This is another site that shows how http://www.pcguide.com/proc/setup/cddriver-c.html
Also go to the web site of the CD drive maker and see if there is a driver available.

I got my cdrom drive to work under DOS thanks to your guys help. It put the driver letter to R:. Is there any way to designate another letter like D: under DOS. If so how would I go about doing that. Thanks-Robbie
check in the autoexec.bat where the driver gets hooked, one of the options there is which drive letter.
Thanks again for the help. You all seem to know alot about DOS, I was wondering if there is anyway to automaticly start my controll software(which is CNCZEUS) when the computer boots. I have it stored on the hard drive and not the cdrom. Thanks again-Robbie
In your Autoexec.bat file, at the end, edit it to read:
CD C:\Cnczeus (the name of the directory where cnczeus is)
CNCZEUS ( or whatever the name of the program is)
I just wanted to thank everyone for your help. All of you helped me get the computer working just the way I wanted it to. Thanks- Robbie
