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 occurs 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 programs the system ROM with a valid image.

Some models also support recovery from a ROMPaq CD.

✎

When the bootblock detects an invalid system ROM, the System Power LED blinks RED eight times, one every second, followed by a two-second pause. You will also hear eight simultaneous beeps. A Boot Block recovery mode message is displayed on the screen (some models).

Desktop Management

http://www.hp.com/support/files.

The beeps continue through five cycles of eight simultaneous beeps and stop; however, the LED

✎

continues blinking until the issue is resolved.

To recover the system after it enters Boot Block recovery mode, complete the following steps:

1. If there is a diskette or a CD in the computer, remove the media and turn off the power.

2. Insert a ROMPaq diskette, bootable drive key, or CD.

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 current 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.

3.5.1 Password Security

The user password prevents unauthorized use of the computer by requiring entry of a password to access applications or data each time the computer is turned on or restarted. The setup password specifically prevents unauthorized access to Computer Setup, and can also be used as an override to the user password. That is, when prompted for the user password, entering the supervisor password instead will allow access to the computer.

A network-wide setup password can be established to enable the system administrator to log in to all network systems to perform maintenance without having to know the user password, even if one has been established.

4.3 PATA Drive Installation Guidelines

CAUTION: HP only supports a PATA hard drive in SATA systems when the PATA hard drive is used in

a MultiBay device.

This computer system board has one Parallel ATA (PATA) channel.

The channel can have up to two devices attached to it. All drives are connected to a channel 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.

4–4 361685-001 Service Reference Guide, dx5150

The drive attached to a channel must have a drive designation. If a drive is attached to the Device 0 cable position and its cable-select jumper is present, the drive is designated as Device

0. Similarly, if a drive is attached to the Device 1 cable position and its cable-select jumper is present, the drive is designated as Device 1.

For optimal performance of a computer system, all drives need to be attached to the PATA channel(s) in a specified sequence. This sequence is determined by the device class of the drives and by specific attach sequence rules.

4.3.1 PATA Device Classes

To determine the best drive attach sequence, ATA/ATAPI drives are segregated into four different classes based upon the bandwidth demands they place on an ATA channel. The most demanding devices are in Class 1 and the least demanding are in Class 4.

General Attach Guidelines

■ The lower the device class number, the faster the device and the more bandwidth required.

■ A drive installed in the Device 0 position receives the greatest possible bandwidth.

4.4 ATA SMART Drives

The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers have built-in drive failure prediction that warns the user or network administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.

Zip

The combination of the file system and the operating system used in the computer determines the maximum usable size of a drive partition. A drive partition is the largest segment of a drive that the operating system can properly access. Therefore, a single hard drive can be subdivided into a number of unique drive partitions in order to make use of all of its space.

Because of the differences in the way that drive sizes are calculated, the size reported by the operating system may differ from that marked on the hard drive or listed in the computer specification. Drive size calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes to the base 2.

5.2 Electrostatic Discharge Information

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.
