resources for either PCI/PnP or legacy ISA devices, and enabling or
disabling the PCI device option ROM for shadow memory.

When set to [No], BIOS configures all the devices in the system. When set
to [Yes] and if you installed a Plug & Play operating system, the operating
system configures the Plug & Play devices not required for boot.
Configuration options: [No] [Yes]

device latency timer register. Configuration options: [32] [64] [96] [128]
