"Disabled" mode.
The above settings will be shown on the screen only if "Manual" is chosen for the resources
controlled by function.
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.
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.
IRQ Resources

PCI / VGA Palette Snoop
Choose Disabled or Enabled.
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 palette will not show up on the
ISA bus if the PCI VGA controller responds to the Write.
