Kevin:
Thank you for your help, I tried to run an antivirus, as you advice, but no virus
were found. Beside I made a try: I remarked (put a REM) all the lines in Config.sys
and Autoexec.bat loding DOS drivers. (The only DOS drivers that are loaded are the
ones for the CD-ROM drive) Then, when I rebooted, the CD-ROM drive were gone from
the Explorer, so I get the CD-ROM drive working only when the DOS drivers for it
are loaded. Can somebody give some advices to solve this problem?
Thank you.
