problem with CD drive

Posted on 2001-08-11
Last Modified: 2013-12-28
I have just upgraded my system from a 166 to a 800 and now whenever I go into Windows it will not detect my CD drive. When in DOS it detects it fine and even worked when I installed WIN 98, however when I was close to the end of the installation and entering the GUI for the 1 time and it begins to load up device drivers the CD drive disappeared and so I could not install the drivers. I have checked in My Computer and it does not show up there either.

The CD drive is set as slave and my HDD as master. The system worked fine before the upgrade and I am using a standard CD drive, not a CDRW.

Any Ideas??

Windows does nor require special drivers for CD's of any kind.

It will cause problems if you loaded DOS drivers.

1) Rename both the autoexec.bat and config.sys and see if this solves the problem.

2) If not, try to download the newest IDE drivers for your specific motherboard.

I hope this helps !

I would first comeup in safemode (hold F8 down when starting too boot up) and then select #3 and come up in safemode. Right-click my computer and go too properties, then device manager. Delete any cd-roms you have here, also check other devices, are your secondary and primary controllers loaded properly etc. Delete any ghost items and reboot. It sounds like either you have a controller driver problem or a little crash occurred and you have more then one cd-rom trying too load and the resultant is none will load. :>) Dave

If you just upgraded your MB  - Which you would have to do to go from a 166 P1 to a PIII   then you need to boot into safe mode and go into the device manager.   Delete all item that can be delete - especially things that are duplicated.  When changing MB  I run thru the entire device manager and delete everything that it will let me delete. Then on regualr reboot - if finds all the neat P&P devices.  Make sure you load the device drivers that came with your MB first  -

I faced such a problem when using DOS 6.22 then upgrading to Installing win98.
If CD Drive is not recognised, in the final stages of windows installation, try to add the commands for the CD drive in config.sys and autoexec.bat
Start in command prompt only
When in command prompt only: you have

You can copy from Dos files to win98 1 files then restart your computer and continue the installation.

Good luck!

You should also run msconfig and make sure you don't have the lines in Dos too load this, as its a waste of resources, the two files would be config.sys and autoexec.bat to look at. Dave

you may also have to remove any registry based items as well related to name of the cdrom .sys file for example nec1600.sys is the cdrom driver sometimes in an upgrade and change of IDE controllers it has a different value associated with the key.  May have to do this as well

I have Both DOS 6.22 and win98 on the same machine!  The boot menu shows another command called Old version of Dos. However, what I suggested is what I tried and worked fine for me.  (Dos6.22 + Win98SE) & (Dos6.22 and Win98)

Condisk, it's entirely possible that machine is running in MS-DOS Compatibility Mode due to the age of the machine, eg: what is now considered legacy equipment. Here's an article that may help you.

if you have ide controller conflicts (see emery800's 1st comment) you could try this quick fix (works most of the time).
go to start - run & type fdisk /mbr (space after fdisk)then click OK. reboot the machine & see if the conflict is gone.
if not go to start - run & type regedit then click OK
click on edit - find & type noide then click on find next button. delete any noide entries found & reboot.

another thing to try is to put the CDrom on the secondary controller
