[SeaBIOS] [RFC PATCH] VGA BIOS init fails if first mode used is graphical

[Gerd Hoffmann]

  Hi,

And here does the plan fail.  There is simply no way to do that.
Bootloaders expect the vga being in 80x25 text mode, period.

> Doesn't Apple's computers do that? I don't know.

Yes, they do.

As long as we are using the IBM PC BIOS interfaces if 1980 (which
seabios is all about):  No way.

With EFI (which apple uses btw) it's another story ...

cheers,
