From 9604f70fdf8e21ec0dbf6eac5e59a0eb8beadd64 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 1 Aug 2013 15:39:11 +0300 Subject: [PATCH] pc: disable pci-info for 1.6 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The BIOS that we ship in 1.6 does not use pci info from host (yet). Several issues turned up (e.g. around winXP boot crashes). So it's safest to disable that interface for 1.6 machine types for now, leave it on for 1.7 as we have enough time to fix issues if any.
