PnP/PCI Configurations
This options configure how PnP (Plug and Play) and PCI expansion cards operate in your system. Both the
ISA and PCI buses on the main board use system IRQs (Interrupt ReQuests) and DMAs (Direct Memory
Access). You must set the IRQ and DMA assignments correctly through the PnP/PCI Configurations Setup
utility for the main board to work properly. Selecting PnP/PCI Configurations on the main board program
screen displays this menu:
T
Init Display First (PCI Slot) : This item allows you to choose the primary display card.
T
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.
T
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.
T
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.
T
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.
T
Assign IRQ for USB (Enabled) : This item enables or disables IRQ allocation for the USB.
T
INT Pin 1-8 Assignment (Auto) : Identifies the interrupt request (IRQ) line assigned to a device
connected to the PCI interface of the system.
T
Maximum Payload Size (4096) : This item specifies the maximum TLP payload size for the PCI
Express devices. The unit is byte.
