Master Boot
Record Security*
Allows you to enable or disable Master Boot Record (MBR)
Security.
When enabled, the BIOS rejects all requests to write to the
MBR on the current bootable disk. Each time the computer is powered on or rebooted, the BIOS compares the MBR of the bootable disk to the previously saved MBR. If changes are detected, you are given the option of saving the MBR on the current bootable disk, restoring the previously-saved MBR, or disabling MBR security. You must know the setup password if one is set.
✎
Disable MBR Security before intentionally changing the formatting or partitioning of the current bootable disk.
Several disk utilities (such as FDISK and FORMAT) attempt to update the MBR.
If MBR Security is enabled and disk accesses are being serviced by the BIOS, write requests to the MBR are rejected, causing the utilities to report errors.
If MBR Security is enabled and disk accesses are being serviced by the operating system, any MBR change will be detected by the BIOS during the next reboot, and an MBR
Security warning message will be displayed.

3.4.3 FailSafe Boot Block ROM
■
■
The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash failure, for example, if a power failure were to occur during a ROM upgrade. The Boot Block is a flash-protected section of the ROM that checks for a valid system ROM flash when power to the system is turned on.
If the system ROM is valid, the system starts normally.
If the system ROM fails the validation check, the FailSafe Boot Block ROM provides enough support to start the system from a ROMPaq diskette, which will program the system
ROM with a valid image.
✎
Some models also support recovery from a ROMPaq CD. ISO ROMPaq images are included with selected models in the downloadable ROM softpaqs.
When the bootblock detects an invalid system ROM, the System Power LED blinks RED 8 times, one every second, followed by a 2-second pause. Also 8 simultaneous beeps will be heard.
A Boot Block recovery mode message is displayed on the screen (some models).
To recover the system after it enters Boot Block recovery mode, complete the following steps:
1. If there is a diskette in the diskette drive or a CD in the CD drive, remove the diskette and
CD and turn off the power.
2. Insert a ROMPaq diskette into the diskette drive or, if permitted on this computer, a
ROMPaq CD into the CD drive.
3. Turn on the computer.
If no ROMPaq diskette or ROMPaq CD is found, you will be prompted to insert one and restart the computer.
If a setup password has been established, the Caps Lock light will turn on and you will be prompted to enter the password.
4. Enter the setup password.
If the system successfully starts from the diskette and successfully reprograms the ROM, then the three keyboard lights will turn on. A rising tone series of beeps also signals successful completion.
5. Remove the diskette or CD and turn the power off.
6. Turn the power on again to restart the computer.
The following table lists the various keyboard light combinations used by the Boot Block ROM
(when a PS/2 keyboard is attached to the computer), and explains the meaning and action associated with each combination.

Clearing Passwords
To disable the power-on or setup password features, or to clear the power-on or setup passwords, complete the following steps:
1. Shut down the operating system properly, then turn off the computer and any external devices, and disconnect the power cord from the power outlet.
2. Disconnect the keyboard, monitor, and any other external devices connected to the computer.
Å WARNING: To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
Ä CAUTION: When the computer is plugged in, the power supply always has voltage applied to the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.
Ä CAUTION: Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. See the Safety & Regulatory Information guide for more information.
3. Remove the computer cover or access panel.
4. Locate the header and jumper.
Service Reference Guide, dc5000 360201-002 3–13
Desktop Management
✎
The password jumper is green so that it can be easily identified. For assistance locating the password jumper and other system board components, see the Illustrated Parts Map (IPM) for that particular system.
5. Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.
6. Replace the computer cover or access panel.
7. Reconnect the external equipment.
8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current passwords and disables the password features.
9. To establish new passwords, repeat steps 1 through 4, replace the password jumper on pins 1 and 2, then repeat steps 6 through 8. Establish the new passwords in Computer Setup. Refer to the Computer Setup (F10) Utility Guide on the Documentation CD for Computer Setup instructions.
3.5.4 DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data on specific hard drives. DriveLock has been implemented as an extension to Computer Setup. It is only available on certain systems and only when DriveLock-capable hard drives are detected.
DriveLock is intended for HP customers for whom data security is the paramount concern. For such customers, the cost of the hard drive and the loss of the data stored on it is inconsequential when compared with the damage that could result from unauthorized access to its contents. In order to balance this level of security with the practical need to accommodate a forgotten password, the HP implementation of DriveLock employs a two-password security scheme. One password is intended to be set and used by a system administrator while the other is typically set and used by the end-user. There is no “back-door” that can be used to unlock the drive if both passwords are lost. Therefore, DriveLock is most safely used when the data contained on the hard drive is replicated on a corporate information system or is regularly backed up.
In the event that both DriveLock passwords are lost, the hard drive is rendered unusable. For users who do not fit the previously defined customer profile, this may be an unacceptable risk.
For users who do fit the customer profile, it may be a tolerable risk given the nature of the data stored on the hard drive.
3–14 360201-002 Service Reference Guide, dc5000
Desktop Management
Using DriveLock
The DriveLock option appears under the Security menu in Computer Setup. The user is presented with options to set the master password or to enable DriveLock. A user password must be provided in order to enable DriveLock. Since the initial configuration of DriveLock is typically performed by a system administrator, a master password should be set first. HP encourages system administrators to set a master password whether they plan to enable
DriveLock or keep it disabled. This will give the administrator the ability to modify DriveLock settings if the drive is locked in the future. Once the master password is set, the system administrator may enable DriveLock or choose to keep it disabled.
If a locked hard drive is present, POST will require a password to unlock the device. If a power-on password is set and it matches the device’s user password, POST will not prompt the user to re-enter the password. Otherwise, the user will be prompted to enter a DriveLock password. Either the master or the user password may be used. Users will have two attempts to enter a correct password. If neither attempt succeeds, POST will continue but the drive will remain inaccessible.
DriveLock Applications
HP recommends that the system administrator be responsible for configuring the hard drive which would involve, among other things, setting the DriveLock master password. In the event that the user forgets the user password or the equipment is passed on to another employee, the master password can always be used to reset the user password and regain access to the hard drive.
HP recommends that corporate system administrators who choose to enable DriveLock also establish a corporate policy for setting and maintaining master passwords. This should be done to prevent a situation where an employee intentionally or unintentionally sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive would be rendered unusable and require replacement. Likewise, by not setting a master password, system administrators may find themselves locked out of a hard drive and unable to perform routine checks for unauthorized software, other asset control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling
DriveLock. Users in this category include personal users or users who do not maintain sensitive data on their hard drives as a common practice. For these users, the potential loss of a hard drive resulting from forgetting both passwords is much greater than the value of the data DriveLock has been designed to protect. Access to Computer Setup and DriveLock can be restricted through the Setup password. By specifying a Setup password and not giving it to end users, system administrators are able to restrict users from enabling DriveLock.

3.5.5 Master Boot Record Security
The Master Boot Record (MBR) contains information needed to successfully boot from a disk and to access the data stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such as those caused by some computer viruses or by the incorrect use of certain disk utilities. It also allows you to recover the “last known good” MBR, should changes to the MBR be detected when the system is restarted.
To enable MBR Security, complete the following steps:
1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart.
2. As soon as the computer is turned on, press and hold the F10 key until you enter Computer
Setup. Press Enter to bypass the title screen, if necessary.
✎
If you do not press the F10 key at the appropriate time, you must turn the computer off, then on again, and press the F10 key again to access the utility.
If you are using a PS/2 keyboard, you may see a Keyboard Error message—disregard it.
3. Select Security > Master Boot Record Security > Enabled.
4. Select Security > Save Master Boot Record.
5. Before exiting, click File > Save Changes and Exit.
When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current bootable disk while in MS-DOS or Windows Safe Mode.
✎
Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot prevent changes that may occur while the operating system is running.
Each time the computer is turned on or restarted, the BIOS compares the MBR of the current bootable disk to the previously saved MBR. If changes are detected and if the current bootable disk is the same disk from which the MBR was previously saved, the following message is displayed:
1999—Master Boot Record has changed.
Press any key to enter Setup to configure MBR Security.
Upon entering Computer Setup, you must

3.6 Fault Notification and Recovery
Fault Notification and Recovery features combine innovative hardware and software technology to prevent the loss of critical data and minimize unplanned downtime.
If the computer is connected to a network managed by HP Client Manager, the computer sends a fault notice to the network management application. With HP Client Manager Software, you can also remotely schedule diagnostics to automatically run on all managed PCs and create a summary report of failed tests.
3.6.1 Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in select HP computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive replacement.
When HP computers are built, each installed hard drive is tested using DPS, and a permanent record of key information is written onto the drive. Each time DPS is run, test results are written to the hard drive. Your service provider can use this information to help diagnose conditions that caused you to run the DPS software. Refer to the Troubleshooting Guide for instructions on using DPS.
3.6.2 Surge-Tolerant Power Supply
An integrated surge-tolerant power supply provides greater reliability when the computer is hit with an unpredictable power surge. This power supply is rated to withstand a power surge of up to 2000 volts without incurring any system downtime or data loss.
3.6.3 Thermal Sensor
The thermal sensor is a hardware and software feature that tracks the internal temperature of the computer. This feature displays a warning message when the normal range is exceeded, which gives you time to take action before internal components are damaged or data is lost.

Ultra ATA Drive Guidelines and Features
Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on factory pre installed, replacement, or option drives. With cable-select, the drive is configured as either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
If you purchase a third-party hard drive, refer to the documentation included with the drive kit to ensure proper cable installation and configuration.
✎
All drives on a controller channel need to have their jumpers either in the cable-select mode or have the individual drive jumper installed on the appropriate Master (Drive/Device 0) or Slave
(Drive/Device 1) position.
When installing a second device on either the primary or secondary controller, you must use an industry standard 80-conductor Ultra ATA cable for optimal performance. These cables have a maximum length of 18 inches and a maximum distance of 6 inches between the two devices for a two-drive cable.
Drives operating at speeds faster than those of the Ultra ATA-33 devices require industry-standard 40-pin, 80-conductor cables to maintain the higher data transfer rates possible with the improved technology.
When using Ultra ATA-133, -100, -66, and slower -33 drives in the same system, each drive will operate at its appropriate data transfer rate.
4.2.1 Cable Layout
The faces of industry-standard cable connectors are color coded for easy recognition:
■
■
■
System board connector = blue face
Device 0 connector = black face
Device 1 connector = gray face
✎
The color code of an industry-standard cable is valid only if the drive’s jumper is in the cable-select position.

On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system board connector and the Drive/Device 1 connector is always the closest to the system board connector.
✎
Some cables may be labeled “Drive 0” instead of “Device 0” and “Drive 1” instead of
“Device 1”.
Most computer system boards have two ATA (IDE) controller channels with a dedicated connector for each controller. One controller is designated as the primary and the other as the secondary controller.
Each of the two controllers can have up to two devices attached to it. Each computer system may therefore have a maximum of four ATA/ATAPI drives. All drives are connected to these controllers using an industry-standard 80-conductor cable.
✎
The industry standard 1.44 MB diskette drive has its own separate channel and is not included as a part of the maximum four drives.
Any drive attached to a controller must have a drive designation. If only a single drive is connected to a controller and its jumper is in the cable-select position, it is designated as the
Master Drive (Drive/Device 0) by its attachment to the Drive/Device 0 cable position. If two cable-selected drives are connected to a single controller, one will be designated by its attachment to the cable as the Master (Drive/Device 0) and the other as Slave (Drive/Device 1).
For optimal performance of a computer system, all drives need to be attached to the ATA controllers in a specified sequence. This sequence is determined by the device class of the drives and by specific attach sequence rules.

*If there are three or more devices, two or more of which are hard drives, two hard drives should be attached to the primary controller first before following the General Attach Sequence Rule.
The rules allow for:
■ Keeping the hard drive on a separate controller channel maximizes drive performance until a fourth device is added.
■ Keeping the hard drives and removable media drives on separate controller channels maximizes compatibility.
■ Keeping the hard drive and the writable optical drive on separate controller channels maximizes optical drive reliability.

Identifying the Chassis, Routine Care, and Disassembly Preparation
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.

Memory
AMD-Based Systems
Computers equipped with AMD-based processors come with Double Data Rate-Synchronous
Dynamic Random Access Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs).
The memory sockets on the system board can be populated with industry-standard DIMMs.
These memory module slots are populated with at least one pre installed memory module. To achieve the maximum memory support, you may be required to replace the pre installed DIMM with a higher capacity DIMM.
If you are adding a second DIMM, it is recommended that you add a DIMM identical to the preinstalled DIMM in order to achieve a higher performing dual channel mode. The system board must be populated with DIMMs of identical type and speed for the system to operate in dual channel mode.
For proper system operation, if the system supports DDR-SDRAM DIMMs, the DIMMs must be industry-standard 184-pin, unbuffered PC 1600 200 MHz- or PC 2100 266 MHz-compliant CAS
Latency 2 or 2.5 (CL = 2 or CL = 2.5), or PC 2700 333 MHz-compliant CAS Latency 2.5 (CL =
2.5) 2.5 volt DDR-SDRAM DIMMs. They must also contain the mandatory Joint Electronic
Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information. DIMMs constructed with x4 SDRAM are not supported; the system will not start using unsupported
DIMMs.
Intel-Based Systems
Computers equipped with Intel-based processors come with double data rate synchronous dynamic random access memory (DDR-SDRAM) dual inline memory modules (DIMMs).
The memory sockets on the system board can be populated with up to four industry-standard
DIMMs. These memory module slots are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 4GB of memory configured in a high-performing dual channel mode.
■
■
■
■
■
For proper system operation, if the computer supports DDR-SDRAM DIMMs, the DIMMs must be industry-standard 184-pin, unbuffered PC2100 266 MHz-, PC2700 333 MHz-, or PC3200
400 MHz-compliant, 2.5 volt DDR-SDRAM DIMMs. The DDR-SDRAM DIMMs must also: support CAS latency 2, 2.5, or 3 (CL = 2, CL = 2.5, CL=3) contain the mandatory JEDEC SPD information
In addition, the computer supports:
128Mbit, 256Mbit, and 512Mbit non-ECC memory technologies single-sided and double-sided DIMMS
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported
Service Reference Guide, dc5000 360201-002 F–1
Memory
The following processor bus frequencies are required for the system to run at the supported memory frequencies.
Memory Frequency
266 MHz
333 MHz
400 MHz
Required Processor Bus Frequency
400 MHz, 533 MHz, or 800 MHz
533 MHz or 800 MHz
800 MHz
If a memory frequency is paired with an unsupported processor bus frequency, the system will run at the highest supported memory speed. For example, if a 333 MHz DIMM is paired with a
400 MHz processor bus, the system will run at 266 MHz, the highest supported memory speed.
✎
The system will not start if you install unsupported DIMMs.
DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.
The system board shown below may be different from the one in your computer.

360201-002 Service Reference Guide, dc5000
Memory
The system will automatically operate in single channel mode or a higher-performing dual channel mode, depending on how the DIMMs are installed.
■ In single channel mode, the maximum operational speed is determined by the slowest DIMM in the system. For example, if the system is populated with a DIMM that is 266 MHz and a second DIMM that is 333 MHz, the system will run at the slower of the two speeds.
■ In dual channel mode, the DIMM pairs must be identically matched. DIMMs in the XMM1 and XMM3 black sockets must be identical; DIMMs in the XMM2 and XMM4 blue sockets must also be identical. Therefore, if you have one preinstalled DIMM in socket XMM1 and are adding a second DIMM, it is recommended that you install an identical DIMM into the
XMM3 socket.
