Hi, can any body tell me what are UpperFilters and
LowerFilters? I need the definition. I had a code 19 error
and friend has mentioned to make changes in the registry
about these. Any help is appreciated. Steve
 
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

(It'll fix code 41 errors too as per the contents of the last kb article)


Filter drivers allow for added functionality to your hardware.
 
Thank you. Issue Resolved. But can anyone 'DEFINE' what
are 'UPPER AND LOWER FILTERS'?

Thanks
Steve
