Even if DMA is enabled on IDE channels, by default UDMA/66 mode is disabled. You can improved
disc performance by enabling it. Open registry by going to START-RUN and entering REGEDIT and
Navigating to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\ {4D36E96AE325-
11CE-BFC1-08002BE10318}\0000]. In right pane look for a key by the name
"EnableUDMA66". If it is there, set its value to 1 if it is not already set to 1. If not, add a dword entry
by the name "EnableUDMA66" and set its value to 1.
