This for me is the holy grail of usefullness and i hope it will be for you too.
The Thing that actually causes the problem is the ide drivers, so all we have to do is revert them to their original state.
1. Extract the following four files from your WINDOWS\Driver Cache\i386\Driver.cab
If you are using a service pack extract the files from the SPx.cab where x is the number of the service pack
Atapi.sys Intlide.sys Pciide.sys Pciidex.sys
2. Copy those four files into the WINDOWS\System32\Drivers folder (overwrite the files if it asks)
3. Merge the following registry file found below. To merge, for those of you who dont know, copy the text into notepad and save it as a .reg file. Exit notepad and double click the file you just made. Say yes to merge and your done!
