PCI_ENABLE_ROM(9)                      Hardware Interfaces                      PCI_ENABLE_ROM(9)



NAME
       pci_enable_rom - enable ROM decoding for a PCI device

SYNOPSIS
       int pci_enable_rom(struct pci_dev * pdev);

ARGUMENTS
       pdev
           PCI device to enable

DESCRIPTION
       Enable ROM decoding on dev. This involves simply turning on the last bit of the PCI ROM
       BAR. Note that some cards may share address decoders between the ROM and other resources,
       so enabling it may disable access to MMIO registers or other card memory.
