all of the boot and Plug and Play compatible devices. However, this capability means absolutely nothing unless you are using a Plug and Play operating sys- tem such as Windows® 95/98. If you set this field to “manual” choose specific resources by going into each of the sub menu that follows this field (a sub menu is preceded by a “¾”). Setting options: Auto (ESCD), Manual.

IRQ Resources

The items are adjustable only when Resources Controlled By is set to Manual. Press <Enter> and you will enter the sub-menu of the items. IRQ Resources list IRQ 3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a type depending on the type of device using the IRQ. Settings are:

bus architecture.

The IRQ will be reserved for further request.

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). For example, if there are two VGA devices in the computer (one PCI and one ISA):

VGA Palette Snoop

Action

Bit Setting

Disabled

Data read or written by the CPU is only directed to the PCI

 

VGA device’s palette registers.

 

 

Enabled

Data read or written by the CPU is directed to both the PCI

 

VGA device’s palette registers and the ISA VGA device’s

 

palette registers, permitting the palette registers of both VGA

 

devices to be identical.

 

 

The setting must be set to Enabled if any ISA bus adapter in the system re- quires VGA palette snooping.

INT Pin 1~8 Assignment

These items specify the IRQ line for each PCI slot. Settings: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, Auto. Selecting Auto allows BIOS to automatically determine the IRQ line for each PCI slot.
