Advanced BIOS Features

► MPS Revision

This feature is only applicable to multiprocessor motherboards as it species the version of

the MPS that the motherboard will use. The MPS is a specication by which PC manufactur-

ers design and build CPU architecture systems with two or more processors. MPS 1.1 was

the original specication. MPS version 1.4 adds extended conguration tables for improved

support of multiple PCI bus congurations and greater expandability in the future. In addition,

MPS 1.4 introduces support for a secondary PCI bus without requiring a PCI bridge. If your

operating system comes with support for MPS 1.4, you should keep the setting as the default

1.4. You also need to enable MPS 1.4 support if you need to make use of the secondary PCI

bus on a motherboard that doesn't come with a PCI bridge. You should only leave it as 1.1

only if you are running an older operating system that only supports MPS 1.1.

► PCI Latency Timer

This item is used to set the PCI latency timer. The value is in unit of PCI cycle for PCI device

latency timer register. Setting values are 32, 64, 96, 128, 160, 192, 224, 248.

This feature controls how long each PCI device can hold the bus before another takes over.

The larger the value, the longer the PCI device can retain control of the bus. Low values for

the PCI Latency Timer will reduce the effective PCI bandwidth while higher values means

every PCI device will have to wait longer before they can get access to the bus, but when they

do get access, they can conduct their transactions for a longer time. Normally, a default value

of 64 cycles is set. Some PCI devices may not agree with longer latency times so if you start

facing problems like stuttering sound or a less responsive system, reduce the latency. Higher

values will actually reduce performance as too much time may be allocated to each PCI device

to the disadvantage of other devices on the bus.
