Ok, I have a big problem with showing the colors of a 4-bit bitmap (16 colors exactly) with 4-bit boot menu (16-color configuration), as I said in this post,
Well, I did some tests and I got the following:
The black colour (RGB: 0,0,0) is not replaced. Ok.
The white colour (RGB: 255,255,255) is replaced with this color (RGB): 130,0,0. Why? Note in EasyBoot the bitmap is properly shown. The colors change when booting from the CD...
Also, this colour 257,214,229 is replaced with 130,0,0, again...
I'm desesperate 
Any help will be very appreciated.

Your problem is that, unlike the EasyBoot frontend (which runs on Windows), the EasyBoot code (which runs from the CD) uses the color table specified in the .ezb file, not the one inside the .bmp file, for both text and the image (this is how graphics works on any 16-color mode).
The only possible workaround I know of is to extract the RGB coordinates from the .BMP and input them manually into EasyBoot.
IMPORTANT: you need to input the colors into EasyBoot's options exactly in the same order they're stored in the bmp (don't know about PhotoShop, but Corel PhotoPAINT certainly displays their order, too).
Btw. You may want to sort the colors in the .BMP by lightness (ascending) first. This is because EasyBoot uses the first and the last colors in the table (normally, black and white) to display the mouse cursor.
[ edit ]
I will try to catch xoben's attention regarding this matter. Hopefully, he may add an "load color table from .BMP" feature, also a "sort color palette by color brightness" tool would be nice, for the .BMP. And finally, I guess the .BMP should be rendered using the in-.EZB palette rather than the one in the BMP file.

Latest public build of EasyBoot (5.0.9.553) supports loading the color palette from 16-color BMPs directly; to use it, click 'Options' (on the 'File' tab), then 'Load ColorTable from BMP).
