Good day and howdy,

I am interested in knowing how grub gets its initial screen size.
The example:

insert live cd (et al)
install distro
install grub to mbr ---

Does grub get it's initial framebuffer/screen settings from the
running kernel during install? and from which kernel process/file does
this information come?
Thank you for your time and
consideration, David Wyckoff, aka

Look for GRUB_GFXMODE/gfxmode variables and you will now.
