MS-7060 Micro ATX Mainboard IRQ Resources The items are adjustable only when Resources Controlled By is set to Manual. Press 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. Setting options: [PCI Device] [Reserved] For Plug & Play compatible devices designed for PCI 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) and the: VGA Palette Snoop Bit Setting Action [Disabled] [Enabled] Data read or written by the CPU is only directed to the PCI VGA device's palette registers. 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 requires VGA palette snooping. 3-22
