2943.0. "NEC/MITSUMI CDROM Challenge" by DECXPS::HENDERSON (Give the world a smile each day) Thu May 29 1997 16:36




 I have a Packard Bell (yes, Packard Bell) 100Mhz 28Megs mem with a NEC 4x 
 CDROM.

 I was attempting to load Microsoft Flight Simulator for Win95 and several
 files woule not load, the problem being the real mode drivers.  I am
 attempting to disable them, and run the protected mode drivers, but I'm
 not quite sure what to do.  I've read several notes in here that seem
 to touch on the solution, but prior to doing anything drastic I wanted
 to be sure I'm doing the right thing.




 The relevant line in my AUTOEXEC.BAT says:


 LH C:\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD0001 /M:20 /S


  The only reference I see in CONFIG.SYS IS:


 DEVICEHIGH=C:\PBTOOLS\NEC_IDE.SYS /D:MSCD0001


 I've "REMed" out the above autoexec.bat line and it of course causes the
 CD to disappear.  If I "install new hardware" it installs it, but goes to
 (apparently) the DOS drivers, and I get a yellow ! next to the CDROM controller
 (which is there all the time, it seems)


 What am I missing?


 Thanks for any help.

        I would assume that if you got a Win95 pc and it came with real mode
    drivers then protected mode drivers don't exist.  You can check out the
    CD vendors support page on their web site to see if there are any newer
    drivers available and if not to ask there support group if there is
    anything you can do.

An ide cdrom (i presume that's the case here) normally does not need a
separate driver to function. Remove the device from config.sys, remove
mscdex from autoexec.bat, reboot and let windows auto-detection do it's job.
Normally it would be no problem then, unless the device has some funnies
in it's ide implementation.
How is this device connected? On the primary controller together with
a hard disk? Or separately on a second ide controller? Of not you may try
the separate controller to avoid a conflict with the hard disk.

  I'm told (per the Mitsumi [supplier of the controller]) Web page, that
  the protected mode drivers are in Win95. 

  According to Microsoft the problem I have encountered occurs, and their
  document on the Knowledge base that deals with protected mode drivers say
  that drivers for Mitsumi are in Win95.

 Do I remove the entire line that refers to MSCDEX from autoexec.bat, or
 just the MSCDEX.EXE statement?

 From what I can tell, the CDROM is connected to the controller which is
 mounted on the sound card.

    Just rem the line out, ie put rem or REM at the beginning of the line
    and put a space after it and it won't load mscdex for you. I also rem
    stuff out of config.sys and haven't had any bad side effects other than
    to learn what I can leave out for W95. It should detect new hardware
    during boot and install the drivers for you (have W95 cdrom handy).

 I wound up re-installing Win95 and it put all the right drivers in there.
 Somehow or other I must have deleted them or something..but I tried
 the suggestions posted here first to no avail.

 Now it works fine, except I can't hear .wav files in Win95

    Jim-Bro,

    no great loss ;')
    
    A quick check might be to look at the volume control panel and see if
    .wav files are either turned right down, or it may even have the 'mute'
    check-box checked ;')

 Thanks, Harry..what I wound up doing is a restore of all factory 
 installed software.  All is well now, thank you.

 (I'd checked all those boxes, etc ;-)
