PnP/ PCI Configurations

This section describes configuring the PCI bus system. PCI (Peripheral Component Inter-

connect) is a system, which allows I/O devices to operate at speeds nearing CPU's when

they communicate with own special components. All the options describes in this section

are important and technical and it is strongly recommended that only experienced users

should make any changes to the default settings.

Init Display First (PCI Slot)

This item allows you to choose the primary display card.

Reset Configuration Data (Disabled)

If you enable this item and restart the system, any Plug and Play configuration data stored

in the BIOS Setup is cleared from memory.

Resources Controlled By (Auto(ESCD))

You should leave this item at the default Auto (ESCD). Under this setting, the system

dynamically allocates resources to Plug and Play devices as they are required.

If you cannot get a legacy ISA (Industry Standard Architecture) expansion card to work

properly, you might be able to solve the problem by changing this item to Manual, and then

opening up the IRQ Resources submenu.

•

IRQ Resources: In the IRQ Resources submenu, if you assign an IRQ to

Legacy ISA, then that Interrupt Request Line is reserved for a legacy ISA

expansion card. Press <Esc> to close the IRQ Resources submenu.

In the Memory Resources submenu, use the first item Reserved Memory Base

to set the start address of the memory you want to reserve for the ISA

expansion card. Use the section item Reserved Memory Length to set the

amount of reserved memory. Press <Esc> to close the Memory Resources

submenu.

PCI/VGA Palette Snoop (Disabled)

This item is designed to overcome problems that can be caused by some non-standard VGA

cards. This board includes a built-in VGA system that does not require palette snooping so

you must leave this item disabled.

Assign IRQ For USB (Enabled)

This item enables or disables the function of assigning IRQ for USB devices.

Maximum Payload Size (4096)

This item specifies the maximum payload size for the PCI Express function.
