Dumb question
 

What is the image format of the GRUB splash?

I want to replace RH's with a custom splash screen, but thus far I only get all colors messed up, even if I use indexed-palettized 8-bit images! (could it be that it uses only 4-bit images or true 8-bit ones?)

it's a gzipped xpm file, 14 (not 16... odd...) colors apparently. i found a guide on google when i changed mine.

please use a more insightful title next time, thanks.

also check stage 13 of this guide

Thanks, guys... and I'll have the new messages posted with a more insightful title next time :)
