Advanced BIOS Features
► Boot Device Priority
This option is used to select the priority for boot devices. After pressing <Enter>, you can
select the device using the Up/Down arrow keys, and change the device priority using <+> or
<->; you can exit this menu by pressing <Esc>.
► Hard Disk Drives
This option is used to specify the boot priority sequence from available hard disk drives.
► Quick Boot
While Enabled, this option allows BIOS to skip certain tests while booting, this will shorten the
time needed to boot the system.
► Quiet Boot
This item is used to enable/disable the quiet boot.
[Disabled] : Displays the normal POST messages.
[Enabled] : Displays OEM customer logo instead of POST messages.
► 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.
► Bootup Num-Lock
This item denes if the keyboard Num Lock key is active when your system is started. The
available settings are: On (default) and Off.
