OK, so we mean the same thing, bascially.

Actually I don't plan to use a bitblit function at all,
because it's not really feasible in standard VGA modes.
What do you mean by that?
Maybe we have different understandings what bitblit means.
My understanding is that bitblit is a raster

We can't re-use the same executable bytes but, with care, we

That would be possible. But then there will be other

It needs a different loader. If you want to support EFI
the right way, it also needs a different kernel -- one
that respect

Hi everyone,
I'm currently working on adding graphics support to the
boot loader. At the moment only the standard VGA mode
640 x 480 at 4 bit depth (16 colors) is supported, but
support for other modes can be added in the future.
Only i386 and amd64 machines with VGA BIOS are supported.
