1. Setting The Palette

I am working on a 3d engine in Euphoria using graphics mode 19. I have a
book on 3d game programming that I am using, and it tells how to use some
BIOS interrupts to set the palette, but I looked them up in a list of
interrupts (Ralph Brown's x86/MSDOS Interrupt List), but couldn't find
them.
I know how to use the palette and all_palette procedures in Euphoria,
        but
they only support intensitys from 0 to 63, and as far as I know, only
integer values are actually used so I can't figure out how to use all 256
intensitys. Even though 63 is equivilent to 255, there is nothing that is
equivelent to 254.

so far as i know, any screen mode using 256 colours can only use from
a set of 262 000 colours (64 red x 64 green x 64 blue)...  to use 256
different intensities, you would have to use high colour (65 536
colours) or true colour (16 777 216 colours), neither of which are
supported by euphoria au moment...

i don't know anything about vesa really, but i know that high colour
and true colour modes are supported by vesa...  if you know a way to
get better vesa modes, make a library for it...  it will be much
appreciated :)
