Intel Desktop Board DQ77KB Technical Product Specification 1.12.1.1 System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off.
Product Description 1.12.1.2 Wake-up Devices and Events Table 12 lists the devices or specific events that can wake the computer from specific states. Table 12. Wake-up Devices and Events These devices/events can wake up the computer… …from this state Power switch S3, S4, S5 RTC alarm S3, S4, S5 (Note) LAN S3, S4, S5 (Note) USB S3 WAKE# S3, S4, S5 Serial port S3 (Note) (Note) Note: S4 implies operating system support only.
Intel Desktop Board DQ77KB Technical Product Specification 1.12.2.1 Power Input When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu. For information about Refer to The location of the internal power connector Figure 14, page 53 The signal names of the internal power connector Table 37, page 64 1.12.2.
Product Description 1.12.2.4 Instantly Available PC Technology CAUTION For Instantly Available PC technology, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current.

Intel Desktop Board DQ77KB Technical Product Specification 2.7.2 Fan Header Current Capability CAUTION The processor fan must be connected to the processor fan header, not to a chassis fan header. Connecting the processor fan to a chassis fan header may result in onboard component damage that will halt fan operation. Table 44 lists the current capability of the fan headers. Table 44. Fan Header Current Capability Fan Header Maximum Available Current Processor fan 2.0 A System fan 1.5 A 2.7.
Technical Reference CAUTION Ensure that the ambient temperature does not exceed the board’s maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.10. CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit.
Intel Desktop Board DQ77KB Technical Product Specification Table 45 provides maximum case temperatures for the components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board. Table 45.
Technical Reference 2.9 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using a parts count method. The calculation is based on the Telcordia SR-332, Issue 2; Method I Case 3 50% electrical stress, 50 ºC ambient. The MTBF prediction is used to estimate repair rates and spare parts requirements. The MTBF data is calculated from predicted data at 50 ºC. The MTBF for the Intel Desktop Board DQ77KB is 90,690 hours. 2.

Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components.
Intel Desktop Board DQ77KB 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. 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.
Overview of BIOS Features 3.6.2 Custom Splash Screen During POST, an Intel® splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. 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. For information about Refer to Intel Integrator Toolkit http://developer.intel.
Intel Desktop Board DQ77KB Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive, removable drive, or the network. The default setting is for the optical drive to be the first boot device, the hard drive second, removable drive third, and the network fourth. 3.8.1 Optical Drive Boot Booting from the optical drive is supported in compliance to the El Torito bootable CD-ROM format specification.
Overview of BIOS Features 3.9 Adjusting Boot Speed These factors affect system boot speed: • • • Selecting and configuring peripherals properly Optimized BIOS boot parameters Enabling the Fast Boot feature 3.9.1 Peripheral Selection and Configuration The following techniques help improve system boot speed: • • • • Choose a hard drive with parameters such as “power-up to data ready” in less than eight seconds that minimizes hard drive startup delays.
Intel Desktop Board DQ77KB Technical Product Specification 3.10 Hard Disk Drive Password Security Feature The Hard Disk Drive Password Security feature blocks read and write accesses to the hard disk drive until the correct password is given. Hard Disk Drive Passwords are set in BIOS SETUP and are prompted for during BIOS POST. For convenient support of S3 resume, the system BIOS will automatically unlock drives on resume from S3.
Overview of BIOS Features NOTE Hard Disk Drive Password Security is not supported in PCH RAID mode. Secured hard disk drives attached to the system when the system is in PCH RAID mode will not be accessible due to the disabling of BIOS Hard Disk Drive Password support. 3.11 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer.
Intel Desktop Board DQ77KB Technical Product Specification NOTE The BIOS complies with NIST Special Publication 800-147 BIOS Protection Guidelines / Recommendations of the National Institute of Standards and Technology. Refer to http://csrc.nist.gov/publications/nistpubs/800-147/NIST-SP800-147-April2011.pdf for more information. 3.
4 Error Messages and Beep Codes 4.1 Speaker Audible error code (beep code) information during POST is routed to the audio codec and can be heard through attached speakers. 4.2 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 54). Table 54. BIOS Beep Codes Type Pattern Frequency F2 Setup/F10 Boot Menu One 0.
Intel Desktop Board DQ77KB Technical Product Specification 4.3 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 55). Table 55. Front-panel Power LED Blink Codes Type Pattern Note F2 Setup/F10 Boot Menu None Prompt 4.4 BIOS update in progress Off when the update begins, then on for 0.5 seconds, then off for 0.5 seconds.
Error Messages and Beep Codes 4.5 Port 80h Power On Self Test (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 POST card that can interface with the Debug header.
