[SeaBIOS] Re: [PATCH 1/1] virtio: do not init non-bootable devices

Hi,

There is no need for a new config file.  qemu can place a HALT entry
into the boot order file (qemu -boot strict=on).  seabios will stop
searching for boot devices when it discovers a HALT entry, so any device
with a lower priority will not be considered for boot.  Typically that
are devices with a default priority because they didn't got a bootindex
assigned.  You can also use that to skip initialization altogether.

cheers,
