If you want to install a PNP compatible OS ( such as Windows 95 ) set to Yes.

Reset Configuration Data:

If you want to reset CMOS IRQ divide hardware device, please selected to [Enabled].

Resources Controlled By:

When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA

information. Instead, it will refer to the items in the setup menu for assigning IRQ &

DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy

information. ESCD (Extended System Configuration Data) provides a detailed

format of the configuration data structures stored in flash memory. Each data structure

defines the resources used by a device or a card in the system. This includes legacy

and PCI/ISA PnP devices.

PCI/VGA Palette Snoop:

When set to [Enabled], multiple VGA devices operating on different buses can handle

data from the CPU on each set of palette registers on every video device. Bit 5 of the

command register in the PCI device configuration space is the VGA Palette Snoop bit

(0 is disabled). Available options are [Enabled] and [Disabled].
