Legacy is the term, which signifies that a resource is assigned to the ISA
Bus and provides non-PnP ISA add-on cards. PCI / ISA PnP signifies that
a resource is assigned to the PCI Bus or provides for ISA PnP add-on
cards and peripherals.
The Choices: Disabled (default), Enabled.
7.3 RESOURCES CONTROLLED BY
By Choosing “Auto (ESCD)” (default), the system BIOS will detect the
system resources and automatically assign the relative IRQ and DMA
channel for each peripheral.By Choosing “Manual”, the user will need to
assign IRQ & DMA for add-on cards. Be sure that there are no IRQ/DMA
and I/O port conflicts.
7.4 IRQ RESOURCES
This submenu will allo w yo u to assign e ac h system inte rrupt 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”.

7.5 PCI / VG A PALETT E SNOOP
Choose Disabled or Enabled. Some graphic co ntrollers which 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 watches
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
