My Win98 (1st edition) machine is now running in "MS-DOS Compatibility mode" instead of being configured for optimal performance. I have not added any new software of drivers. I also cannot see my CD-ROM drive or a new hard drive that I want to install on this machine. Must I reinstall Windows once again?! Maybe I can reinstall Windows over itself?
Thanks!

Your problem may be due to IDE controllers,reference Microsoft knowledgebase article Q151911,Q130179 and Q51911.
Reinstalling the OS may not clear up the problem,it is a registry problem.
Go to device manager and see if their are any yellow exclamation marks.

A good trouble shooter start would be to check your Autoexec.bat and Config.sys for any programs (.exe) files being loaded. These would be programs being loaded into DOS before the Windows drivers. Programs like CD ROM .sys files can force MD-DOS Compatibility mode.

REM out these lines and restart. That should eliminate most of the software problems.

Good Luck

Your comments helped but were a little late, as I have already checked these areas. Thank you regardless though!
