CHAPTER 7 Award BIOS Installation This chapter describes the different settings available in the Award BIOS that comes with the board. This chapter offers information on the Award BIOS installation utility.
Chapter 7 7.1 AMI BIOS SETUP Starting Setup Your computer comes with a hardware configuration program called BIOS Setup that allows you to view and set system parameters. The BIOS (Basic Input / Output System) is a layer of software, called ‘firmware’, that translates instructions from software (such as the operating system) into instructions that the computer hardware can understand. The BIOS settings also identify installed devices and establish special features.
The Main BIOS setup screen has two main frames. The left frame dis- plays all the options that can be configured. Grayed-out options cannot be configured; options in blue can be. The right frame displays the key leg- end. Above the key legend is an area reserved for a text message. When an option is selected in the left frame, it is highlighted in white. Often a text message will accompany it. 7.2 System Overview Use this option to change the system time and date.
7.3 Advanced Setting CPU Configuration Press “Enter” to CPU Configuration setting. CPU configuration differs from writing an executable program. It is equivalent to setting dip switches or jumpers on a circuit board. The executing program has no way to change this configuration.
IDE/SATA Configuration The IDE Configuration menu is used to change and/or set the configuration of the IDE devices installed in the system.
Super IO Configuration Allows you to select the Serial Port base address.
Hardware Health Configuration CPU Temperature The onboard hardware monitor automatically detects and displays the CPU temperatures.
ACPI Configuration Advanced Configuration and Power Interface (ACPI) provides an open standard for unified operating system-centric device configuration and power management.
ACPI APIC Support Allows you to enable or disable the Advanced Configuration and Power Interface (ACPI) support in the Application-Specific Integrated Circuit (ASIC). When set to Enabled, the ACPI APCI table pointer is included in the RSDT pointer list. The options: [Disabled], [Enabled]. AMI OEMB table Set this value to allow the ACPI BIOS to add a pointer to an OEMB table in the Root System Description Table (RSDT) table.
AHCI Configuration AHCI mode is enabled in the BIOS where 3 settings are commonly available: IDE, AHCI, and RAID. The last two (AHCI and RAID) require a floppy disk with the driver that can be introduced into the operating system installation through F6. Otherwise, the hard disks won't be detected.
ASF Configuration Alert Standard Format The term "system manageability" represents a wide range of technologies that enable remote system access and control in both OS-present and OS-absent environments.
Intel AMT Configuration Allows you to enable or disable iAMT support. Active Management Technology (AMT) is hardware-based technology for remotely managing and securing PCs out-of-band.
Intel Robson Configuration Allows you to configure Intel Robson Tech. The technology attempts to decrease hard drive usage by moving frequently accessed data over to the flash memory. Flash memory can be accessed faster than hard drives and requires less power to operate, thereby allowing laptops to operate faster while also being more power efficient.
Intel VT-d Configuration Allows you to configure Intel VT-d Tech.
MPS Configuration I771 Motherboard User Manual 54
PCI Express Configuration The Expansion Slot Utility allows you to change the number of "lanes" available for PCIe cards to utilize.
Smbios Configuration System Management BIOS (SMBIOS) specification defines data structures (and access methods) in a BIOS which allows a user or application to store and retrieve information specifically about the computer in question.
USB Configuration Legacy USB Support Allows you to enable or disable support for USB devices on legacy operating system (OS). Setting to Auto allows the system to detect the presence of USB devices at startup. If detected, the USB controller legacy mode is enabled. If no USB device is detected, the legacy USB support is disabled. The options: [Disabled], [Enabled], [Auto].USB 2.0 Controller Allows you to enable or disable the USB 2.0 controller. The options: [Disabled] [Enabled].
RTC Configuration Real time clock alarm is a feature that can be used to allow a computer to 'wake up' after shut down to execute tasks every day or on a certain day I771 Motherboard User Manual 58
7.4 PCI/PnP The PCI PnP menu items allow you to change the advanced settings for PCI/PnP devices. The menu includes setting IRQ and DMA channel resources for either PCI/ PnP or legacy ISA devices, and setting the memory size block for legacy ISA devices Clear NVRAM Clear NVRAM during system boot. The options: [No], [Yes]. Plug & Play O/S When set to [No], BIOS configures all the devices in the system.
PCI Latency Timer Allows you to select the value in units of PCI clocks for the PCI device latency timer register. The options: [32] [64] [96] [128] [160] [192] [224] [248]. Allocate IRQ to PCI VGA When set to [Yes], BIOS assigns an IRQ to PCI VGA card if the card requests for an IRQ. When set to [No], BIOS does not assign an IRQ to the PCI VGA card even if requested. The options: [No] [Yes].
Palette Snooping When set to [Enabled], the palette snooping feature informs the PCI devices that an ISA graphics device is installed in the system so that the latter can function correctly. The options: [Disabled] [Enabled]. PCI IDE BusMaster the BIOS use PCI bus mastering for reading/writing to IDE device. The options: [Disabled], [Enabled].
OffBoard PCI/ISA IDE Card Allows you to set the PCI slot number. The options: [Auto], [PCI Slot1], [PCI Slot2], [PCI Slot 3], [PCI Slot4], [PCI Slot5], [PCI Slot6]. IRQ3,4,5,7,9,10,11,14,15 Allows you to specify IRQ that is available to be used by PCI/PnP or Legacy ISA device. The options: [Available], [Reserved].
DMA Channel 0,1,3,5,6,7 DMA Channel PCI/PMP functions. The options: [Available], [Reserved]. Reserved Memory Size Set the size of memory block to reserve for legacy ISA devices. The options: [Disabled], [16 K], [32 K], [64 K].
I771 Motherboard User Manual 64
7.5 Boot Boot Setting Configuration Quick Boot Enable this item allows the BIOS to skip some power on self test (POST) while booting to decrease the time needed to boot the system. When set to [Disabled], BIOS performs all the POST items. The options: [Disabled], [Enabled].
Quiet Boot Allows you to display Normal POST message or OEM logo. The options: [Disabled], [Enabled]. Boot up Num-Lock Allows you to select the power-on state for the NumLock. The options: [Off], [On].
