Scan for VGA option rom
Attempting to init PCI bdf 00000130 (dev/ven 47521002)
Attempting to map option rom on dev 00000130
Option rom sizing returned fff80000 fffe0000
Inspecting possible rom at fff80000 (dv=47521002 bdf=00000130)
No option rom signature (got 0000ffff)
Turning on vga console
Starting SeaBIOS

I don't think it's worth pursuing.  Let's just use cbfs.

Thanks,
