(Default: Other OS) &&CSM Support Enables or disables UEFI CSM (Compatibility Support Module) to support a legacy PC boot process. Always Enables UEFI CSM. (Default) Never Disables UEFI CSM and supports UEFI BIOS boot process only. This item is configurable only when Windows 8 Features is set to Windows 8 or Windows 8 WHQL. &&Boot Mode Selection Allows you to select which type of operating system to boot. UEFI and Legacy Allows booting from operating systems that support legacy option ROM or UEFI option ROM. (Default) Legacy Only Allows booting from operating systems that only support legacy option ROM. UEFI Only Allows booting from operating systems that only support UEFI option ROM. This item is configurable only when CSM Support is set to Always. &&LAN PXE Boot Option ROM Allows you to select whether to enable the legacy option ROM for the LAN controller. (Default: Disabled) This item is configurable only when CSM Support is set to Always. &&Storage Boot Option Control Allows you to select whether to enable the UEFI or legacy option ROM for the storage device controller. Disabled Disables option ROM. Legacy Only Enables legacy option ROM only. (Default) UEFI Only Enables UEFI option ROM only. Legacy First Enables legacy option ROM first. UEFI First Enables UEFI option ROM first. This item is configurable only when CSM Support is set to Always. &&Other PCI Device ROM Priority Allows you to select whether to enable the UEFI or Legacy option ROM for the PCI device controller other than the LAN, storage device, and graphics controllers. Legacy OpROM Enables legacy Option ROM only. UEFI OpROM Enables UEFI Option ROM only. (Default) This item is configurable only when CSM Support is set to Always. &&Network stack Disables or enables booting from the network to install a GPT format OS, such as installing the OS from the Windows Deployment Services server. (Default: Disabled) &&Ipv4 PXE Support Enables or disables IPv4 PXE Support. This item is configurable only when Network stack is enabled. &&Ipv6 PXE Support Enables or disables IPv6 PXE Support. This item is configurable only when Network stack is enabled. (Note) This item is present only when you install a CPU that supports this feature. For more information about Intel CPUs' unique features, please visit Intel's website. &&Administrator Password Allows you to configure an administrator password. Press on this item, type the password, and then press . You will be requested to confirm the password. Type the password again and press . You must enter the administrator password (or user password) at system startup and when entering BIOS Setup. Differing from the user password, the administrator password allows you to make changes to all BIOS settings. &&User Password Allows you to configure a user password. Press on this item, type the password, and then press . You will be requested to confirm the password. Type the password again and press . You must enter the administrator password (or user password) at system startup and when entering BIOS Setup. However, the user password only allows you to make changes to certain BIOS settings but not all. To cancel the password, press on the password item and when requested for the password, enter the correct one first. When prompted for a new password, press without entering any password. Press again when prompted to confirm. 2-5 Peripherals &&Initial Display Output Specifies the first initiation of the monitor display from the installed PCI graphics card, PCI Express graphics card or the onboard graphics. IGFX Sets the onboard graphics as the first display. PCIe 1 Slot Sets the graphics card on the PCIEX16 slot as the first display. (Default) PCI Sets the graphics card on the PCI slot as the first display. &&XHCI Mode Allows you to determine the operating mode for the xHCI controller in OS. Smart Auto This mode is available only when the BIOS supports the xHCI controller in the pre-boot environment. This mode is similar to Auto, but it adds the capability to route the ports to xHCI or EHCI according to setting used in previous boots (for non-G3 boot) in the pre-boot environment. This allows the use of USB 3.0 devices prior to OS boot. xHCI controller enabling and rerouting should follow the steps in Auto, when previous boot routs ports to EHCI. Note: This is the recommended mode when BIOS has xHCI pre- boot support. (Default) Auto BIOS routes the sharable ports to EHCI controller. Then it uses ACPI protocols to provide an option to enable the xHCI controller and reroute the sharable ports. Note: This is the recommended mode when BIOS does NOT have xHCI pre-boot support. Enabled All shared ports are eventually routed to the xHCI controller during the BIOS boot process. If BIOS does not have pre-boot support for the xHCI controller, it should initially route the sharable ports to the EHCI controller and then prior to OS boot it should route the ports to x...
