Restart system in safe mode by shutting down and as soon as you see starting windows 98 press f8 and choose safe mode, once windows is in safe proceed to remove all ide controllers from device manager, Windows will find the new hardware after you restart windows in normal mode, 99% of the time this will solve this type of problem.  

Let me know
Good Luck

firstbase,

CAUSE:
The protected-mode driver for the hard disk controller was not properly initialized when you started Windows previously. When this occurs, a NOIDE entry is placed in the registry, preventing Windows from making future attempts to initialize the protected-mode driver......  From MS KnowledgeBase article.

Problem resolution available here:

Let me know if you need more.

Ralph

Win95 switches to MS-DOS compatability mode when the 32 bit drivers are somehow corrupted or missing.  Since it can not read the 32 bit drivers, it automatically install the 16 bit drivers  and I guess hopes that you will figure out what happened! As I understand it, your problem is that your CD does not work in Windows now.  In order to correct this situation, you need to access the CD while your in the DOS mode so that you can reload windows and the neccessary drivers (I hope thats the right analysis !)  In order to access the cd-rom in MSDOS mode, you need to load your real-mode drivers for the CD into your Config.sys file.  Windows does not use this file, but DOS still requires it.  You also have to check to make sure that WIN98 has not REMed out the MSCDEX.exe in your Autoexec.bat file.  The reason for checking this is because WIN98, during installation, remarks out your 16 bit drivers and installs its own 32-bit protected mode drivers.  The unremarked call from your previous autoexec.bat file is moved over to DOSSTART.bat file.  The real mode drivers in your Config.sys file, however, are not remarked out.  Now when you go into the MS-DOS mode, Mscdex.exe is called by Dosstart.bat and because the real mode driver has now been loaded, you will now be able to access your CD-ROM drive in the MS-DOS mode. Try it, It really works...Jim

Do you have a floppy in the drive, if yes then remove the disk. And if not then you will have use a windows 98 Boot disk to transfer the system files back to the harddrive. If you need help in doing this then let us know and I or someone else can help you to do this.

Boot off the floppy drive and then once at a prompt type the following
sys c:
once the system is transfered, remove the disk and try to boot the system again and see what happens next. Let me know.

Can you scan for boot sector viruses, it is possible that you may some kind of boot sector virus that is causing this to happen.  Also ren your config.sys file to config.bak and also the autoexec.bat to autoexec.bak once you do this reboot and see what happens, we are not going anywhere and will be here to help you get this thing working.  One other thing to try is boot off your floppy again and while at the dos prompt type the following.

fdisk /mbr

Once you do that reboot your computer after you take out disk and then see what happens.
Let us know.

I had the same problem.  It was related to a bad entry in my system.ini file. It was a bear to find !!

run msinfo32, then hit 'tools', 'system configuration utility' I selective took things out (unchecked), rebooted and looked for the results. CD Drives showed up when system.ini was disabled.

Finally narrowed this to a line in system.ini

device=C:\windows\system\vcdremap.vxd

commented this out and all now works !!
