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: IRQ-3/ 4/ 5/ 7/ 9/ 10/ 11/ 12/ 14/ 15

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.

Frequency/Voltage Control
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)
CPU Clock Ratio
This field allows you to adjust the CPU clock ratio. When the CPU clock ratio is locked by the CPU
manufacturer, you will not be able to adjust this field.
Options: Available options will depend on the CPU installed.
