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) Disables the function. Enabled Enables the function. Assign IRQ For VGA Lets the user choose which IRQ to assign for the VGA. The Choices: Enabled (default), Disabled.
