| 1627 | * The standard boot ROM sequence for an x86 machine uses the BIOS | ||
| 1628 | * to select an initial video card for boot display. This boot video | ||

| 1631 | * card with this copy. On laptops this copy has to be used since | ||
| 1632 | * the main ROM may be compressed or combined with another image. | ||
| 1633 | * See pci_map_rom() for use of this flag. IORESOURCE_ROM_SHADOW | ||
