Document Number 376223-001. 1st Edition January 2005 Key Specifications Key Specifications Processor Type: Intel Pentium 4 or Intel Celeron RAM Type: DDR2 PC3200 non-ECC Maximum RAM Supported: Up to 4 GB depending on the model Expansion Bus: PCI 2.3, X1 slot Graphics Adapter Integrated controller or PCI 2.3 support depending on model Hard drive interface: SATA* I/O Interfaces: Serial (1 std, 1 optional), parallel (1), USB 2.0 (8), diskette drive (1), audio (5: 2 front, 3 back) *You can connect a PATA hard drive. However, HP does not recommend its use . System Setup and Boot Basic system information regarding file, storage, security, and power configuration is maintained in the Setup Utility held in the system ROM. The Setup Utility is accessed by pressing the F10 key as soon as the computer is turned on. If the screen prompt opportunity is missed, a restart will be necessary.

Device Configuration - Lists all installed BIOS storage devices. The following options appear when a device is selected. Diskette Type (legacy diskette drives only) Identifies the highest capacity media type accepted by the diskette drive. Drive Emulation (IDE devices only) Selects drive type emulation for storage Drive Type Emulation Options ATAPI Zip Drive None (treated as other), diskette (treated as diskette drive). ATA Hard drive None (treated as other), disk (treated as hard drive. LegacyDiskette No emulation available. IDE CD-ROM No emulation available. ATAPI LS-120 None (treated as other), diskette. Default Values IDE/SATA Multisector Selects number of sectors transferred. Transfers Options are disabled, 8, and 16. 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. Controls the type of data transfer used by the BIOS to fulfill read and write requests. DMA is used when Enable is selected. PIO is used when Disable is selected. SATA Emulation.Specifies whether the SATA and PATA controllers function as two separate or one combined controller. Separate IDE Controller emulation is recommended for Windows 2000 and XP. Combined IDE Controller emulation is recommended for operating systems that only support one IDE controller. Computer Setup Menu (Continued) Heading Storage (continued) Security Power Advanced (advanced users only) Option / Description Storage IDE Controller. Enable/disable. Options (ctd) Primary SATA Controller - Enable/disable. Secondary SATA Controller - Enable/disable. DPS Self-Test - Allows execution of the Drive Protection System (DPS) tests on ATA hard drives capable of the SMART self-tests. Boot Order - Specifies the prioritized order of potential boot devices. Each entry may be included or excluded from consideration as a boot source. Use F9 during POST to select a one-time override to the boot order specified here. 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. Embedded Security - Enable/disable Embedded Security device. Reset device to Factory Settings. Device Security - Enable/disable serial/parallel/USB ports, system audio, NIC (some models). Network Service Boot - Enables/disables Network Service Boot. System IDs - Allows setting of Asset and Ownership Tags, chassis serial number, keyboard locale, and Universal Unique Identifier (UUID). DriveLock - Allows assignment of master or user password for MultiBay hard drive(s). Data Execution Prevention - Enable/disable to prevent OS Security breaches. Master Boot Record (MBR) Security - Enable/disable BIOS MBR change reporting and write-protection. Save MBR - Saves backup copy of MBR of current bootable disk. Restore MBR - Restores MBR to current bootable disk. OS Power Management - Enable/disable processor voltage and frequency reduction during run and idle times; ACPI S3 support. Hardware Power Management - Enable/disable SATA bus and/or device power management. Thermal - Fan idle mode to control minimum fan speed. 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 bootblock 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 minimize 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 (reprogramming) 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 reconfiguration 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.
