Leslie,
If you already have a bitmap,
Open your main level .wdl and have a look at this:
-replace logodark.pcx
/////////////////////////////////////////////////
// define a splash screen with the required A4/A5 logo
bmap splashmap = <logodark.pcx>; // the default logo in templates
panel splashscreen {
bmap = splashmap;
flags = refresh,d3d;
}
