Looks good. Those "SET_INT_VECTOR comments" should be removed.

4ce12047a9 - added PCI ROM support to the Bochs BIOS (works with both pcivga and cirrus) 
- scan for VGABIOS ROM after rombios32 init
  - copy PCI ROM to shadow RAM at 0xc0000 and enable it
  - NOTE: this feature does not work with BIOS-bochs-legacy, so we should recommend to use the
    default BIOS for PCI display adapters
  - TODO: load VGABIOS ROM from the vga code instead of main.cc if PCI is disabled
