From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gleb Natapov Subject: [PATCH] support piix PAM registers in KVM Date: Tue, 21 Sep 2010 14:31:42 +0200 Message-ID: <20100921123142.GB11145@redhat.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: seabios@seabios.org, kvm@vger.kernel.org To: mtosatti@redhat.com Return-path: Received: from mx1.redhat.com ([209.132.183.28]:31252 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753350Ab0IUMb6 (ORCPT ); Tue, 21 Sep 2010 08:31:58 -0400 Content-Disposition: inline Sender: kvm-owner@vger.kernel.org List-ID: Without this BIOS fails to remap 0xf0000 memory from ROM to RAM so writes to F-segment modify ROM content instead of memory copy. Since QEMU does not reloads ROMs during reset on next boot modified copy of BIOS is used.
