commit 8cafe3ea3c336c52771752c0fcebb24f8ac1b4d1 Author: Damien Zammit damien@zamaudio.com Date: Wed Aug 19 15:23:32 2015 +1000
gigabyte/ga-g41m-es2l: Add mainboard
Board uses x4x native raminit
Board boots into Debian 8 with full graphics
VGA: - VGA native init works in grub with analog connector - Fails to boot with both channels of ram populated
