I am running windows 98. Recently my computer has stopped detecting my cd-rom and cd-rw drives. In the device manager i am showing conflicts on my floppy disk controller, as well as on my primary ide controller (dual fifo) and secondary ide controller (dual fifo). Windows also is reporting under the performance tab that drives A: & C: are running in MS-Compatability Mode. Any ideas how to get my drives back and get rid of conflicts?

Download and extract the latest IDE drivers for the chipset on your motherboard.
If a name brand PC, start there.
If not, start with the motherboard mfg.
If you have trouble identifying them, check out the tools at www.motherboards.org
or www.wimsbios.com

Next, delete ALL IDE devices in device manager.
Re-boot the system, and point the driver wizzard to the folder where you extracted the driver files to.

Good try but it didn't work. I update the drivers and still get the same problem.

Hi

There are many possiblities:
1- Check for virus.
2- find a subkey in registry with the name "NOIDE" then delete it.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS\NOIDE
3-Check your config.sys for the CD-ROM driver and remove it. It is DOS driver on the otherhand windows driver will be installed by Windows.

4- The wrong CD-ROM driver is installed.

Good luck

Option number 3 helped me. I had to remove some boxes that were checked under the file system option in the perfomance tab. Thank you!!!
