Subject: [PATCH] support piix PAM registers in KVM
Date: Tue, 21 Sep 2010 14:31:42 +0200 [thread overview]
Message-ID: <20100921123142.GB11145@redhat.com> (raw)
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.
