Your advice worked! Although, in a strange way - I first friend
extra-root-pci set to 255 without luck. It enumerated the bus but no option
rom was found/ran.
I then built sgabios and added to the image along with the option to fix
the duplicate serial output issue. After flashing and rebooting I was
presented with a SeaBIOS prompt on my screen, which was unexpected but
SeaBIOS then booted from the flash drive and I was presented with a linux
kernel panic. I'll need to investigate that one, but it's looking promising.
Thanks again for your help!

Thanks for taking a look and thanks for your suggestions.
So, SeaBIOS is not designed to detect and run a VGA option rom from a
video card? I was hoping that I could get SeaBIOS
to act similar to the
vendor BIOS and not have to use a serial based console.
SeaBIOS can use VGA on PCIe cards - the problem appears to be that
SeaBIOS isn't scanning all the PCI buses on the machine. Try setting
extra-pci-roots as described previously.
Any ideas on SeaBIOS not booting from hard disks
or USB storage devices?
I suspect the problem with USB storage is really just a result of VGA
not working and the behavior of third-party bootloaders when a vgabios
isn't found. See my previous email.
