x86 boot is strange. The BIOS boots from the "first hard disk" What
extboot allows you do to is redefine to the bios what constitutes the
"first hard disk".
This is the motivation for making it a -drive option. Perhaps this is
something we want to hide from the user but that was the motivation.
For instance, it would not be possible to define a boot sequence of
"first virtio disk, then second virtio disk, then cdrom" because we
can't present two disks as the first hard disk.
If extboot supported BCV and our bios did, the above would be possible.
