I know how make to make this game work like a charm without unplunging the ide cables...
First, download this software.

1-Extract all the files and open WPCREDIT.EXE
2-Press Ctrl+C and Select "Ide Controler"
3-Replace the 71 values by 72 as marked in the red frame
4-Make sure the Device Id is 0572
5-Now close it down and run the game
When your pc is restarted the values you set will be back to default
But you will probably know how to do that again.
And for nforce motherboards, just use starfucker, select the secound item in the list, and disable all cd-rom, dvd drives.
