From 35658f8da582ecfa7d3fbe511cfe6b1c01d18dd1 Mon Sep 17 00:00:00 2001 From: "kaf24@firebug.cl.cam.ac.uk" Date: Fri, 21 Oct 2005 10:24:35 +0100 Subject: [PATCH] Update one file from qemu 0.71 for Cirrus Logic VGA device model. Using the older device model running pinball game on windows with full screen can cause guest crash.
