Description
If enabled, the system is forced to update Extended System
Configuration Data (ESCD) and then is automatically set to the
disabled mode.
If disabled, the system ESCD will update only when the new
configuration varies from the last one.
When set to auto ESCD, the system BIOS will detect the system
resources and automatically assign the relative IRQ and DMA channel
for each peripheral.
When set to manual, you have to assign the IRQ and DMA for add-on
cards.
This parameter can be configured if the Resources Controlled By is set
to Manual.
It allows you to assign each system interrupt a type, depending on the
type of device using the interrupt.
Enables or disables the system graphic card to allow VGA palette
snooping.
Set the maximum payload size for Transaction packets (TLP).
