Intel Desktop Board DH67CL Product Guide Legacy I/O 20 The board’s Legacy I/O Controller provides the following legacy features: • Low pin count (LPC) interface • Consumer Infrared (CIR) support • Serial IRQ interface compatible with serialized IRQ support for Conventional PCI bus systems • Intelligent power management, including a programmable wake-up event interface BIOS The BIOS Setup program provides configuration options for the Legacy I/O controller. The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash device. The BIOS can be updated by following the instructions in Chapter 3 starting on page 61. SATA Auto Configuration If you install a SATA device (such as a hard drive) in your computer, the autoconfiguration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing a SATA device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. The BIOS sets SATA to ACHI mode by default. PCI*/PCI Express Auto Configuration If you install a Conventional PCI or PCI Express add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a Conventional PCI or PCI Express add-in card.
Security Passwords Desktop Board Features The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup and for booting the computer, with the following restrictions: • The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing at the password prompt of Setup gives the user restricted access to Setup. • If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered. • Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer. For instructions on resetting the password, go to Clearing Passwords on page 53. Hardware Management The hardware management features of Intel Desktop Board DH67CL enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following: • Fan speed monitoring and control • Thermal and voltage monitoring • Chassis intrusion detection Hardware Monitoring and Fan Speed Control The features of the hardware monitoring and fan speed control include: • Smart fan control provided by the legacy I/O controller, delivering acousticallyoptimized thermal management. Fan speed controllers and sensors are integrated into the legacy I/O controller. • Thermal sensors in the processor and Intel H67 PCH, as well as near the processor voltage regulators and system memory. • Monitoring of system voltages to detect levels above or below acceptable values • Thermally monitored closed-loop fan control for all fans that can adjust fan speed as needed. Fan Monitoring Fan monitoring can be observed via the BIOS Setup program, Intel ® Desktop Utilities, or third-party software. 21
