From 1cac5004e953506166e980da5776d5cc1c176d79 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 30 Jan 2008 13:33:02 +0100 Subject: x86 setup: display VESA graphics modes in vga=ask menu Display VESA graphics modes, with their mode IDs, in the vga=ask menu. Most VESA mode numbers are platform-dependent, so it helps to have an easy way to display them. Based in part on a patch by Petr Vandrovec . Cc: Petr Vandrovec Signed-off-by: H.
