Desktop Board Features Legacy I/O The board's Legacy I/O Controller provides the following legacy features: • One serial port header • Serial IRQ interface compatible with serialized IRQ support for Conventional PCI bus systems • Intelligent power management, including a programmable wake-up event interface • Conventional PCI bus power management support The BIOS Setup program provides configuration options for the Legacy I/O controller. BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the PCI/PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash memory device. The BIOS can be updated by following the instructions in Chapter 3 starting on page 67. SATA Auto Configuration If you install a SATA device (such as a hard disk 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. PCI*/PCI Express Auto Configuration If you install a Conventional PCI or PCI Express add-in card in your computer, the PCI/PCI Express 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. BIOS Security Passwords 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. 21
