Pnp/Pci Configurations - ECS PN1 SLI2 Extreme User Manual

3.3-6 PnP/PCI Configurations

These options configure how PnP (Plug and Play) and PCI expansion cards
operate in your system. Both the the ISA and PCI buses on the motherboard
use system IRQs (Interrup ReQuests) and DMAs (Direct Memory Access).
You must set up the IRQ and DMA assignments correctly through the
PnP/PCI Configurations Setup utility for the motherboard to work properly.
Selecting PnP/PCI Configurations on the main program screen displays this
menu:

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.

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 (Press Enter):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.
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)
Names the interrupt request(IRQ) line assigned to the USB on your system.Activity
of the selected IRQ always awakens the system.
Maximum Payload Size (4096)
This item specifies the maximum payload size for the PCI Express function.
