PX875P PRO/ PX875P

P.A.T. Mode

Allows user to enable “Performance Acceleration Technology” in FSB800/ DDR400 mode, using PAT can employ a specially configured “shortcut” or “by pass” when accessing memory, slicing several clock cycles from the access times and reducing conventional latency factors. Preliminary tests have shown that system performance and efficiency can be increased about 3% - 5%.

If you want to set the “Turbo” or the “Ultra” options, please make sure your memory DIMMs can be overclock. Overclocking can damage the memory DIMMs or other sensitive components.

Options: Auto (default)Compatible (Slowest)PAT-DisabledTurboUltra (Fastest)

PnP/PCI Configurations

Reset Configuration Data

Select “Enabled” to reset the Extended System Configuration Data (ESCD) if you have installed a new add-on card and the system reconfiguration has caused such a serious conflict that the OS cannot boot. Options: Disabled (default)Enabled

Resources Controlled By

BIOS can automatically configure all the boot and Plug and Play compatible devices. If you choose Auto, you will not be able to manually assign IRQ DMA and memory base address fields, since BIOS automatically assigns them. Options: Auto (ESCD) (default)Manual

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.

Options: Disabled (default)Enabled

PCI Latency Timer (CLK)

This item allows you to set up the PCI Latency Time (0-255). If you select the “32” it will optimize PCI speeds. Options: 0-25532 (default)

PCI SLOT1- 5

This item allows you to select an IRQ address for PCI slot 1-5.
