seabios question

Hi, Avi

Recently I want to update hvm vcpu add/remove feature of KVM.
I go through qemu-kvm, find that original boch vbios code (i.e, qemu-kvm/kvm/bios/acpi-dsdt.asl, ...) has been removed.

Now qemu-kvm use seabios git repo http://git.kernel.org/?p=virt/kvm/seabios.git;a=summary as its vbios, right?
If I want to update seabios dsdt logic, may I build and then copy seabios/out/bios.bin to qemu-kvm/pc-bios/bios.bin?
and, I rebuild qemu-kvm and my update of seabios will take effect at kvm qemu side, right?

Thanks,
Jinsong--

Correct. You also need a 'make install', since qemu will pick up the
bios from /usr/local/share/qemu/bios.bin.

Seabios not yet supports vCPU hot plug/unplug.
