When Windows starts, a progress bar indicating the status of the boot process appears on top of a Windows logo background. You can't use the registry or a configuration file (e.g., .ini file) to modify this background. However, you can modify the bitmap resource, which stores the background image, in the ntoskrnl.exe (the Windows kernel) file that's active during the boot process. You'll need to copy the ntoskrnl.exe file and replace the bitmap resource with the bitmap you want to use. If you want to modify an XP boot screen but you're not up to the challenge of manually modifying ntoskrnl.exe, you might want to try BootXP.

You'll need two applications to modify the ntoskrnl.exe file:

Jasc Sofware's Paint Shop Pro to modify an XP boot screen (if you're modifying a Win2K boot screen, you can use any paint program because, unlike XP and as I explain later, Win2K doesn't rely on color palettes)

The boot screen bitmap must consist of 16 colors. When you modify an XP boot screen, you'll need to download a 16-color Windows palette and 16-color viewable palette from the Windows 2000 FAQ Web site. Otherwise, the bitmap image that you create for your boot screen will appear as just a black image.
