Advanced BIOS Features CMOS Setup Utility - Copyright (C) 1985-2009, American Megatrends, Inc. Advanced BIOS Features ► Boot Device Priority ► Hard Disk Drives Quick Boot Quiet Boot PCI Latency Timer Bootup Num-Lock PCI IDE BusMaster [[PPrreessssEEnntteerr]] Help Item [Press Enter] [Enabled] Specifies the [Enabled] Boot Device [64] Priority sequence . [On] [Enabled] 3 Move Enter:Select +/-/:Value F10:Save ESC:Exit F1:General Help F9:Optimized Defaults ► Boot Device Priority This option is used to select the priority for boot devices. After pressing , 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 . ► 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 defines if the keyboard Num Lock key is active when your system is started. The available settings are: On (default) and Off. 25
