Loaded up windows tonight and found both my sony CD-ROM
and CD-RW not in my computer, i went to the system menu
and in hardware devices there is !! marks next to both cd
drives and there is also one next to SM Bus Controller, i
uninstalled all of them hoping they would reinstall and
befine, the cd roms will install there drivers but the SM
Bus COntroller can't find its drivers and leaving the CD
Drives not working. THis is the first time its happened
and the computers is now about 9 months old

Hi there Andrew,

Delete upper/lower filters from registry, download
registry patch from here:
http://www.dougknox.com/xp/scripts/xp_cd_dvd_fix.vbs

NOTE: If your anti-virus software warns you of
a "malicious" script, this is normal if you have "Script
Safe" or similar technology enabled. These scripts are
not malicious, but they do make changes to the System
Registry.

HTH, happy 2004!

Goto http://aumha.org/win5/a/xpcd.php#problems
See the second "problem" (read the caveats)
Run the provided registry patch

That should fix your problem (basically, a filter driver is missing or
non-operational, the registry patch will delete the filter drivers
references for your cdrom(s))


Basically, the reg file from above carries out the steps displayed at this
website

Did you load the MB chipset drivers? Intel's is infinst and
VIA's is Hyperion, there are also chipset drivers for SIS
and nvidia. If you have a propriatory system you will have
to go to the mfgs page.
