OK, so that isn’t the way I want to go (I don’t think).  Using the 
romheaders utility on the file I have extracted gives me:

Image 1:
PCI Expansion ROM Header:
   Signature: 0x55aa (Ok)
   CPU unique data: 0x80 0xe9 0x92 0xf9 0x30 0x30 0x30 0x30
                    0x30 0x30 0x30 0x30 0x30 0x30 0x30 0x30
   Pointer to PCI Data Structure: 0x0040

PCI Data Structure:
   Signature: 0x50434952 'PCIR' (Ok)
   Vendor ID: 0x8086
   Device ID: 0x0406
   Vital Product Data:  0x001c
   PCI Data Structure Length: 0x001c (28 bytes)
   PCI Data Structure Revision: 0x03
   Class Code: 0x030000 (VGA Display controller)
   Image Length: 0x0080 blocks (65536 bytes)
   Revision Level of Code/Data: 0x0000
   Code Type: 0x00 (Intel x86)
   Last-Image Flag: 0x80 (last image in rom)
   Reserved: 0x8000

Platform specific data for x86 compliant option rom:
   Initialization Size: 0x80 (65536 bytes)
   Entry point for INIT function: 0xf998

I don’t know at this point in the project what the payload will be - it 
might be SeaBIOS, TianoCore or GRUB2 so do I need to give the video BIOS 
a normal file name and select VGA_ROM_RUN?
