IRQ RESOURCES
This submenu will allow you to assign each system interrupt a type,
depending on the type of device using the interrupt. When you press the
"Press Enter" tag, you will be directed to a submenu that will allow you to
configure the system interrupts. This is only configurable when
"Resources Controlled By" is set to "Manual".
IRQ-3 assigned to PCI Device

IRQ-9 assigned to PCI Device
IRQ-10 assigned to PCI Device
IRQ-11 assigned to PCI Device
IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device

PCI / VGA PALETTE SNOOP
Choose Disabled or Enabled. Some graphic controllers that are not VGA
compatible take the output from a VGA controller and map it to their
display as a way to provide boot information and VGA compatibility.
However, the color information coming from the VGA controller is drawn
from the palette table inside the VGA controller to generate the proper
colors, and the graphic controller needs to know what is in the palette of
the VGA controller. To do this, the non-VGA graphic controller watch for
the Write access to the VGA palette and registers the snoop data. In PCI
based systems, where the VGA controller is on the PCI bus and a
non-VGA graphic controller is on an ISA bus, the Write Access to the
palette will not show up on the ISA bus if the PCI VGA controller responds
to the Write.
In this case, the PCI VGA controller should not respond to the Write, it
should only snoop the data and permit the access to be forwarded to the
ISA bus. The non-VGA ISA graphic controller can then snoop the data on
the ISA bus. Unless you have the above situation, you should disable
this option.
Disabled (default) disable the function.
Enabled Enable the function.
