Computer is a HP Pavilion 6535, windows 98 platform. CDROM was replaced with a Yamaha CD2200EZ CD rewritable. Worked fine till the hard drive was reformatted. Restored the computer with the HP recovery disk. Tried to load CD burning software andit does not recognize a CD rewritable drive. Looked in device manager and CDROM is not present. Also noticed Primary and Secondary IDE hard disk controllers have exclamtion marks on them. CDROM can read data but no audio or video. What happened?

Boot in to safe mode by hitting F8 or CTRL.
If your system will not do this go into BIOS and disable quiet boot. Start the computer normally and edit msdos.sys. You might need to change it from read only

1. Start -> Run -> type in "command" and hit enter. (no quotes)

2. Type "cd\" and hit enter. You should be at the root now (C:\). Type "edit msdos.sys" and hit enter.

3. Change the option "BootMulti=0" to "BootMulti=1"

4. Change the option "BootKeys=0" to "BootKeys=1"

Restart computer and go into safe mode.
When it comes up go to device manager and delete all references under the CD & Hard Disk

Next

Choose Start -> Run -> Regedit

HKEY_LOCAL_MACHINE
Enum
MF
CHILD0000
CHILD0001

Delete both CHILD0000 and CHILD0001. Those are the Primary and Secondary
Controllers.

HKEY_LOCAL_MACHINE
System
CurrentControlSet
Services
Class
hdc
000x (where x is a ascending numeral)

Remove all the numeric keys under the hdc key.

Rebootand let windows detect all the hardware.

You should have the driver disk that came with the Yahmaha. If not then download. Win98 will let you know when it wants the driver disk or the Win98 disk. If your sound still doesn't work after that then most HP systems come with an Application Recovery CD where you can go in and pick and choose what Apps or driver you want to load.

Having exclamation mark in hard drive controllers, have a problem in boot sector, sometimes co'z by the virus.

Try to write a new boot record...and here's how...

FirsT if you have a startup (Win98 Start-up)
Start-it up without CD-ROm Support
run FDISK /MBR....this will write a new boot record to your Drive C..
Then reset...
Removed the startup... and boot...

Hope it works...

When You restored the computer with the hp recovery disk it used the drivers for your old cd-rom instead of detecting the new one. I suggest you go into device manger and remove the device completely, then go to windows\inf\other folder and delete everything there(make sure u have show all files turned on because the inf folder is a system folder) Then restart your computer, you should be able to reinstall the correct drivers at that point.

You should have received a diskette with an upgrade for the cdrom, if not please call HP customer support for that diskette. You can also goto roxio and updrade the original adaptec software. This is a known issue with that system, and Hp should send you the diskette.
