I'm using "Windows XP professional - Service Pack 3".

To simplify versions, can you use the latest QEMU - 2.3.0-rc4 and use
the seabios and seavgabios that come with that version of qemu.  I
tested that here and don't see corruption with those versions.  This
is the command line I used:

../qemu/qemu-git/x86_64-softmmu/qemu-system-x86_64 -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios -m 512 -hda winxp-test-wbc -enable-kvm
