From 126a2a8a78731b0f913ac0f876b4238359a483b8 Mon Sep 17 00:00:00 2001 From: Damien Zammit Date: Fri, 28 Nov 2014 15:59:10 +1100 Subject: gigabyte/ga-b75m-d3h: Add new Intel mainboard This is based on LENOVO X230 port. Board boots to linux via SATA or USB. All USB ports are working. Remaining Issues: 1. Native raminit sometimes fails with "timC write discovery failed" even without changing the ram configuration. I suggest altering the native raminit code so that it reboots if that message appears to give a chance for the boot process to recover. 2. VGA does not work. Native graphics initialization only supports LVDS and the VGA Option ROM still hangs when run in SeaBIOS.
