Replacing boot screens in SP2?

[HyperHacker]

I've followed the directions to replace the boot screen in the sticky thread, but they don't seem to have worked. Nothing has changed after replaing bitmap #1 (and I checked that it had been saved, the hacked ntoskrnl.exe was loaded, etc). The bitmaps are numbered 1 to 15 with 9 to 12 missing. No other bitmap is large enough to be the boot screen. After replacing #5 (a Windows logo and "Microsoft Windows"), the entire boot screen went black except the progress bar. I don't want to use the /NOGUIBOOT method because then I'd lose the progress bar.

Any ideas?
