ATA disks only Transfer Mode ATA devices only Selects active data transfer mode. Options are PIO 0, Max PIO, Enhanced DMA, Ultra DMA 0, and Max UDMA. Translation Mode (ATA disks only) Selects translation mode to enable the BIOS to access disks partitioned and formatted on other systems and may be necessary for users of older versions of Unix. Options are: Automatic, Bit-Shift, LBA Assisted, User, and None. NOTE: The translation mode automatically selected by BIOS should usually not be changed. Translation Parameters (ATA disks only) Allows you to specify disk parameters logical cylinders (max. of 1024), heads (max. of 256), and sectors per track (max. of 63) used by BIOS to translate disk I/O requests. Fields are visible and changeable only when drive translation mode is set to User. Storage Options Removable Media Boot. Enables/disables ability to boot system from removable media. Legacy Diskette Write. Enables/disables ability to write data to legacy diskettes. BIOS DMA Data Transfers. Allows control of BIOS I/O requests. Enable allows read and write with DMA transfers. Disable allows read and write with PIO transfers. SATA Emulation. Allows method of accessing SATA controller and devices. Default is Separate IDE Controller. Option is combined IDE Controller IDE Controller. Enable/disable primary IDE controller. Primary SATA Controller - Enable/disable. Secondary SATA Controller - Enable/disable. Computer Setup Menu (Continued) Heading Storage (continued) Security Power Advanced (advanced users only) Option / Description DPS Self-Test - Allows execution of self-tests on ATA hard drives capable of Drive Protection System (DPS) tests. Boot Order - Allows selection of priority in the boot sequence. Each drive may be included or excluded. May use F9 on rebooting to select a one time boot override to a selected bootable device. Setup Password - Enable/disable setup (administrator) password. Power-On Password - Enable/disable power-on password. Password Options (appears if Power-On or Setup password is set) Enable/disable password for warm boot. Smart Cover Lock (some models) - Enable/disable Smart Cover Lock.

Power-On Options - Select POST mode for QuickBoot, FullBoot, FullBoot every 1-30 days; Enable/disable POST messages; Enable/disable option ROM prompt; Enable/disable I/O APIC mode; Select computer state after power loss; Select wakeup boot source; Enable/disable POST delay (for slow hard drives); Enable/disable ACPI/USB buffers; Enable/ disable NIC option ROM download; Enable/disable Hyper-threading. BIOS Power-On - Set computer to turn on at specific time of day. Onboard Devices - Set resources for onboard devices (serial/parallel port or diskette controller). PCI Devices - Lists currently installed PCI devices and IRQ settings. Allows configuration/disabling of devices (no effect on APIC systems) Bus Options - Enable/disable PCI bus mastering, PCI VGA palette snooping, PCI SERR# function, and ECC on select systems. Device Options - Set printer mode (bidirectional output only); Num Lock State;Wake-up events; processor cache; unique sleep state blink patterns; integrated video; monitor tracking; NIC PXE Option ROM download. PCI VGA Configuration - Allows selection of VGA controller (if multiple PCI video controllers are installed). Failsafe Boot Block ROM The computer comes with a reprogrammable flash system ROM (read only memory). NOTE: No USB device of any type will function during boot block recovery. To upgrade the ROM, you may: a. Order an upgraded ROMPaq diskette from HP. or b. Download the latest ROMPaq images from the HP Web site (www.hp.com). All ROM images used with HPQFlash and SSM are digitally signed to ensure authenticity and mini-mize potential corruption. Your system ROM includes a Failsafe Boot Block that is protected during the flash process and allows the computer to be restarted in the unlikely event of an unsuccessful ROM flash. If the system detects an invalid system ROM during the boot sequence the system will sound one long and three short beeps, flash the three keyboard LEDs twice, and display a recovery mode message on the screen. To recover from the Boot Block recovery mode complete the following steps: 1. Remove any diskettes from the diskette drive and turn off power. 2. Insert a ROMPaq diskette into the diskette drive or a bootable CD-ROM into an IDE CDROM drive. (Bootable ISO CDs are available on the Web at www.hp.com.) 3. Turn on power to the system. 4. If a Setup password has been established, the Caps Lock LED will come on to prompt you for the password. Enter the password. 5. A successful boot and ROM flashing (re-programming) with a ROMPaq diskette is indicated by the three keyboard LEDs turning on and a series of beeps rising in tone. Security Functions The system offers independent Power-On and Setup passwords for system and data protection. The Power-On password protects the computer from unauthorized access by prompting the user for a password during power up. The Setup password protects the computer from unauthorized or inadvertent re-configuration of legacy device resource settings or ROM flash upgrade by prompting the user for a password prior to entering the Setup Utility. To establish a password: 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the computer. 2. As soon as the computer is turned on, press and hold F10 until you enter Computer Setup. Press Enter to bypass the title screen, if necessary. If you do not press F10 as soon as the computer starts, a restart will be necessary. 3. Select Security, then select Setup Password or Power-On Password and follow the instructions on the screen. 4. Before exiting, click File > Save Changes and Exit.
