Biostar K8NHA Pro [56/60] Irq resources

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

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”.

PCI / VG A Palette Snoop

Choose Disabled or Enabled. Some graphic controllers 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 contro ller 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.

In this case, the P CI VGA controller shou ld 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) Disables the function.

Enabled Enables the function.
