I recommend that you re-install the IDE driver for the chipset on your motherboard.

1. Simple method (does not always correct all problems)
From device manager (right click on the my computer icon, and select properties)
remove all 3 IDE devices.

Close device manager, and re-boot the computer.
Windows should find the IDE controllers, and may ask for the Windows CD if files are missing.

2. Best method
Identify who made your motherboard, and what chipset is on it.

If this is a name brand system, just go to the mfg. support page, and download the IDE driver.

If not a name brand system, you can use the tools at either www.motherboards.org
or www.wimsbios.com to identify your motherboard.
Then, go to the manufactures web site, and download the latest IDE driver.

Extract (if a .zip file) and install the driver.

Your CD drive should now function properly.

Or you can shut down the computer open the case and remove the cable from the cdrom and reboot. The computer will not find the cdrom, them shut down and reconnect the cdrom and reboot if it still dont see the cdrom try another know good one from a friend or buy one they are vary cheap now. If you have two ide plugins on your mother board and are only using one try buying another cable and set the cdrom to master with the small jumper on the back and use the new cable to connect it. And reboot. Let me know if it dose or dose not work I have more ideas.

Sorry what O/S are you using? Win95, 98, ME, ECT? The cable could have gone bad or the cdrom itself. Some virus will do what you are talking about too.

i guess its my fault, i didnt say that its on a pc that im trying to install 98se on. it has no o/s. i wiped hard drive and it shows cdrom on startup but when installing windows it says missing cdromrv.sys.

To get the CDROM to work and do the win98 install you need to create a startup disk. The drivers for a CDROM are included and will work with allmost any CD drive.

From the control panel select add remove programs. Then select the startup disk tab. Make sure your system BIOS will allow you to boot to the A drive. Boot to the disk and select CDROM support. The boot disk will install a temporary virtual drive called ram drive. In a PC with only one partition on the main hard drive the virtual drive will be D and the CDROM will be E. After you install windows the virtual drive will be gone and the CDROM will then be the D drive. I've had people think the CD is still not working because they're looking fo it to be D drive and never think totype in "E:" .

Change to the E drive and run win 98 setup

Download a boot disk for windows 98 from www.bootdisk.com
Then you should have the necessary drivers for your cdrom you're looking for. Otherwise visit a friend with a windows 98 saystem and make a bootdisk from there. You do that by going to start
settings
control panel
add/remove software
the third tab is create a startup disk
good luck

your falling off the open list top 100 so i'ld recommend closing this one if you're still having issues and reopening it with todays date. Let us know what you've tried and where your at in fixing and we'll keep sending updates.
Hope it's going well.

Are you using a restore CD for other system or the Original MS Win98Se CD?
Does your system BIOS support booting from CD rom?
Also, does the Windows installation stops in the middle (reboot? etc), or does not go at all because of the CDrom file missing?

It looks like you are using the disk to boot the system at the beginning, but remove the disk in once the system boot. Guessing because you did not tell us where or when the error message show up.

If you have the original driver for the CD Rom drive,

Get a bootable system disk from any PC with Windows 98 SE with minimum DOS required files such as format, fdisk, sys, edit, etc.

Boot with the system disk. Then, fdisk and format the HDD and install the system files to HDD.
Install (Copy) the CD driver files to HDD.
Make sure the CD rom is readable from DOS.

You have not installed the Win98SE yet.
Now if the cd is readable from "C" prompt, you can install the Win98SE.
At the end, Win98Se will edit the content of the
Autoexec.bat and Config.sys.
Make sure both files have required lines for the CDrom to run. Otherwise, the system will not read the Cd in DOS mode.

If you don't have the original CD rom driver.
Let me know the CDrom manufacturer from label, I will find the driver for you or at least let you know the link to download the file.
Good luck.

Here's a download site for sys files.... but it does not have the cdrom"rv".sys ...

Try renaming the general cdrom.sys to cdromrv.sys and see if that will work.
