Code:
from the lilo-README
VGA=<mode> Specifies the VGA text mode that should be selected when
booting. The following values are recognized (case is ignored):
NORMAL select normal 80x25 text mode.
EXTENDED select 80x50 text mode. The word EXTENDED can be
abbreviated to EXT.
ASK stop and ask for user input (at boot time).
<number> use the corresponding text mode. A list of available modes
can be obtained by booting with vga=ask and pressing [Enter].
Cheers,
