Note The numbered subkeys that are listed earlier correspond to the primary and secondary IDE channels on a computer that contains a single IDE controller. If your computer contains two IDE controllers, the numbered subkeys for the primary and secondary IDE channels for each of the two controllers may be:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0002

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0003

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0004

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0005

To verify that you have located the correct subkey, verify that the DriverDesc value for the subkey contains the string value "Primary IDE Channel" or the string value "Secondary IDE Channel."

I assume your talking about winxp and how it flips back to PIO mode at times. Well it's inevitable no matter what you do. So when it happens the easiest way instead of all that stuff is to:

a) simply delete your primary and/or secondary IDE channel in Device Manager.
b) reboot, let it redetect it
c) reboot and your set

It appears you need new atapi.sys driver from August 2003, but I can't find direct link for d/l.

or for those of u with intel chipsets, just install the 2.3 Intel Appliaction accelerator... My ripping went up from 2.1x to 8x

when this was happening to me I discovered that there was a BIOS firmware upgrade that needed to be applied. After I did that I've never had it switch to PIO mode on me since.
