3 Overview of BIOS Features 3.1 Introduction The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and Plug and Play support. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs are identified as CBQ4510H.86A.
Intel Desktop Board DQ45CB Technical Product Specification Table 31 lists the BIOS Setup program menu features. Table 31.
Overview of BIOS Features 3.4 System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components.
Intel Desktop Board DQ45CB Technical Product Specification 3.5 Legacy USB Support Legacy USB support enables USB devices to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3.
Overview of BIOS Features 3.6 BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: • • Intel® Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from the file location on the Web.
Intel Desktop Board DQ45CB Technical Product Specification 3.7 BIOS Recovery It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. Table 33 lists the drives and media types that can and cannot be used for BIOS recovery. The BIOS recovery media does not need to be made bootable. Table 33.
Overview of BIOS Features 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drive, USB drive, USB flash drive, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. If enabled, the last default boot device is the network. 3.8.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification.
Intel Desktop Board DQ45CB Technical Product Specification 3.9 Adjusting Boot Speed These factors affect system boot speed: • • 3.9.1 Selecting and configuring peripherals properly Optimized BIOS boot parameters Peripheral Selection and Configuration The following techniques help improve system boot speed: • • • • 3.9.2 Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays.
Overview of BIOS Features 3.10 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: • • • • • • • The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode.

4 Error Messages and Beep Codes 4.1 Speaker The board-mounted speaker provides audible error code (beep code) information during POST. 4.2 For information about Refer to The location of the onboard speaker Figure 1, page 11 BIOS Beep Codes Whenever a recoverable error occurs during POST, the BIOS causes the board’s speaker to beep an error message describing the problem (see Table 36). Table 36. Beep Codes Type 4.
Intel Desktop Board DQ45CB Technical Product Specification 4.4 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST codes requires a PCI bus add-in card, often called a POST card.
