► IDE Detect Time Out
This item is used to select the time out value for detecting ATA/ATAPI devices. If the checking
time is over the set value, the system will skip it.
► MPS Revision
This feature is only applicable to multiprocessor motherboards as it specifies the version of the
MPS that the motherboard will use. The MPS is a specification by which PC manufacturers
design and build CPU architecture systems with two or more processors. MPS 1.1 was the
original specification. MPS version 1.4 adds extended configuration tables for improved
support of multiple PCI bus configurations 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.
► Quiet Boot
This item is used to enable/disable the quiet boot.
