I downloaded a new boot screen once, replaced the .ini file (forget the exact name of the file), and then rebooted. Got the bluescreen. Of course, that was a long time ago and I didn't know what I was doing. I had to repair the boot from the windows CD lol.
I think I got it working later with bootxp, like yohon was talking about. But I dont remember doing much. Seemed kinda pointless.
Have fun.
