I have a am486dx4 120mhz with 24 megs ram. No sound card. Creative 8X cd-rom. It has a 1.2 gig hard-drive. I have just installed MS_DOS 6.22 on the machine and it works fine. I have tried numerous drivers and programs that try and configure dos to recognize the cdrom, none work correctly. I have a copy of mscdex.exe residing on c:\mscdex.exe. Nothing I do seems to work. Any suggestions will be a life saver. No windows95/98/nt will be put on this machine, just DOS. Thank you for your suggestions.
