IRQ Resources
When resources are controlled manually, you can assign each system interrupt a type, depending on the type of device using the interrupt. This is only configurable when “Resources Controlled By” is set to “Manual”.
Options: | assigned to | PCI device |
PCI / VGA Palette Snoop
Some graphic controllers that 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.
Options: Disabled (default)、Enabled
PCI Latency Timer (CLK)
This item allows you to set up the PCI Latency Time
PCI SLOT1- 5
This item allows you to select an IRQ address for your PCI slot
Options: Auto (default)、3、4、5、7、9、10、11、12、14、15
Frequency/Voltage Control
CPU Host Frequency (MHz)
This item displays the CPU Host Frequency. You can set this field to a maximum of 255 (or 550 with the CPU which has the CPU clock is 200 MHz.). The minimum setting is determined by the CPU that you have installed.
CPU Clock Ratio 8X
When you enable this field, the CPU clock ratio is fixed at “8X” and overrides the entry for the “CPU Clock Ratio” field (see “CPU Clock Ratio” field). The CPU clock ratio is used, in part, to determine the CPU clock speed (CPU clock speed = CPU clock ratio * CPU Host Frequency). It has been shown that a higher “CPU Host Frequency” and a lower “CPU Clock Ratio” is more desirable when calculating a desired CPU clock speed. This field allows you to set the CPU clock ratio to a lower than usual value (8X), allowing you to use higher “CPU Host Frequency” values.
When you disable this field, the CPU clock ratio will be determined by the “CPU Clock Ratio” field. This item will only appear when the CPU clock ratio is not locked by the CPU manufacturer.
Options: Enabled, Disabled (default)
