From 800379f7aa07ca54898faa2c51e6f41ea5b228df Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Mon, 1 Mar 2010 08:34:19 +0000 Subject: This patch implements MBI (modular bios interface) support to the i830 chipset. This is needed on the IP1000T to get VGA output. The VGA option rom will ask through an SMI for hardware specifics (in form of a VBT, video bios table) which the SMI handler copies into the VGA option rom.
