Overview of BIOS Features 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.
6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. 7. Additional USB legacy feature options can be access by using Intel Integrator Toolkit.
Intel Desktop Board DX79SR Technical Product Specification To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions. BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: ®...
The Intel Integrator’s Toolkit that is available from Intel can be used to create a custom splash screen. NOTE If you add a custom splash screen, it will share space with the Intel branded logo. Refer to For information about ®...
Intel Desktop Board DX79SR Technical Product Specification Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drive, USB drive, USB flash drive, optical drive, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the optical drive third.
It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen.
Intel Desktop Board DX79SR Technical Product Specification 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: •...

Error Messages and Beep Codes Speaker The board-mounted speaker provides audible error code (beep code) information during POST. For information about Refer to The location of the onboard speaker Figure 1, page 13 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).
Intel Desktop Board DX79SR Technical Product Specification Front-panel Power LED Blink Codes Whenever a recoverable error occurs during POST, the BIOS causes the board’s front panel power LED to blink an error message describing the problem (see Table 37). Table 37. Front-panel Power LED Blink Codes...
Error Messages and Beep Codes 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.
