From 1a410ae58f28eeab32fa87626cfd5a663ba33c51 Mon Sep 17 00:00:00 2001 From: Bernhard Walle Date: Tue, 13 May 2014 23:40:56 +0200 Subject: [PATCH 2\/2] Update x86emu from X.org This commit updates the x86emu copy from X.org tarball (ftp:\/\/mirror.csclub.uwaterloo.ca\/x.org\/current\/src\/xserver\/xorg-server-1.12.2.tar.bz2). This fixes a compatibility issue between v86d and SeaBIOS VGA BIOS where the leal instruction is not decoded properly. Read the http:\/\/thread.gmane.org\/gmane.comp.emulators.qemu\/271806 thread for more details.
