Without BBS > there is no ability to have a unified boot device selection. SeaBIOS does support BBS (both BEVs and BCVs). Also, under qemu, SeaBIOS will run option roms with memory writable and then lock the memory after the POST phase (as is required by the spec). SeaBIOS also support PMM (both temporary allocations and the PCIv3 extensions for permanent memory). Finally, I plan to commit a series of patches to SeaBIOS which add support for booting from USB drives. I imagine adding virtio support to SeaBIOS would not be difficult if someone wishes to take that on. -Kevin -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
