Main Memory

There are two memory module slots on the system board for installing main memory. You
can install 266 MHz DDR-SDRAM modules; these are available in 128, 256, 512 MB and
1 GB memory modules. You can install a maximum of 2 GB of memory (2 x 1 GB modules).

System Features

DIMM slots

You can only use non-ECC memory modules.

DDR-SDRAM

Short for Double Data Rate-Synchronous DRAM, DDR-SDRAM is a type of SDRAM that
supports data transfers on both edges of each clock cycle, effectively doubling the memory chip’s
data throughput. DDR-SDRAM also consumes less power. DDR-SDRAM is also called
SDRAM II.

While the new memory module is clocked at the same speed as normal SDRAM, it is able to
transport double the amount of data by using the rising as well as falling edge of the clock signal
for data transfers. DDR-SDRAM has another important enhancement over SDRAM. Its voltage
supply uses only 2.5 V, instead of 3.3 V. This and the lower capacities inside the memory chips
lead to significantly reduced power consumption.

DDR-SDRAM DIMMs are not compatible with SDRAM DIMMs. The new DDR-DIMMs come
with 184 instead of the 168 pins used by SDRAM-DIMMs. The module itself looks almost
identical to SDRAM, but it has only one notch on its connector surface.

Ultra-ATA/100 Hard Drives

ATA (AT Attachment) is a disk drive implementation designed to integrate the controller into the
drive itself, thereby reducing interface costs. ATA is also known as IDE (Integrated Drive
Electronics).

Ultra ATA/100 is the latest generation of the ATA interface, it increases burst data rates
significantly over previous versions of the protocol. Also known as Ultra DMA/100 and
Feature ATA, Ultra ATA/100 allows host computers to send and receive data at 100 MB/s. The
result is maximum disk performance under PCI local bus environments.

At its fast burst data rates, Ultra ATA/100 removes bottlenecks associated with data transfers,
especially during sequential operations. Ultra ATA/100 also delivers heightened data integrity to
the EIDE interface through use of a 40-pin 80-conductor cable, and CRC (Cyclic Redundancy
Check) error detection code. The 80-conductor cable reduces crosstalk and improves signal
integrity by providing 40 additional ground lines between the 40-pin IDE signal and ground
lines. The connector is plug-compatible with existing 40-pin headers, and the incremental cost
for the cable should be minimal.

By increasing the burst transfer rates of IDE drives, Ultra ATA/100 brings the effective transfer
rate of the system’s bus and a drive’s internal data rate that much closer into balance. Ultra
ATA/100 allows greater system throughput, particularly for long sequential transfers required by
audio/visual applications.

System Features

Ultra ATA/100 hard drives are backwards compatible with earlier devices but will take on the
speed of earlier devices when used in their stead.

S.M.A.R.T. or Self Monitoring Analysis and Reporting Technology allows the hard drive to

✎

report certain types of degradation or impending failure. This allows the operating system to take
the necessary precautions and warn the user. The system is comprised of software that resides
both on the disk drive and on the host computer. The disk drive software monitors the internal
performance of the motors, media, heads, and electronics of the drive, while the host software
monitors the overall reliability status of the drive. The reliability status is determined through the
analysis of the drive's internal performance level and the comparison of internal performance
levels to predetermined threshold limits.

Digital Versatile Disk (DVD) Technology

Digital Versatile Disc (DVD) is a medium for the distribution of from 4.7 to 17 GB of digital data
on a 120 mm (4.75 inch) disc. This huge volume of data (CD-ROMs can store 680 MB) can be
used to store up to nine hours of studio quality video and multi-channel surround-sound audio,
highly interactive multimedia computer programs, 30 hours of CD-quality audio, or anything
else that can be represented as digital data.

A DVD looks like a CD-ROM: it is a silvery disc, 4.75 inches in diameter, with a hole in the
center. Like a CD, data is recorded on the disc in a spiral trail of tiny pits, and the discs are read
using a laser beam. The DVD’s larger capacity is achieved by making the pits smaller and the
spiral tighter, and by recording the data in as many as four layers, two on each side of the disc.

To read these tightly packed discs, lasers that produce a shorter wavelength beam of light are
required, as are more accurate aiming and focusing mechanisms. In fact, the focusing mechanism
is the technology that allows data to be recorded on two layers. To read the second layer, the
reader simply focuses the laser a little deeper into the disc, where the second layer of data is
recorded.

Not only are two layer discs possible, but so are double-sided discs. The availability of
four layers is what gives DVD its 17 GB capacity.

Audio features of DVD-Video

A DVD-Video disc can have up to 8 audio tracks (streams). Each track can be in one of
three formats:

Dolby Digital (Dolby AC-3): 1 to 5.1 channels

■

MPEG-2 audio: 1 to 5.1 or 7.1 channels

■

LPCM: 1 to 8 channels

■

Dolby Digital is multi-channel digital audio, using lossy AC-3 coding technology from original
PCM with a sample rate of 48 kHz at up to 24 bits. The bitrate is 64 kbps to 448 kbps, with
384 being the normal rate for 5.1 channels and 192 being the normal rate for stereo (with or
without surround encoding).

Technical Reference Guide 2–13

System Features

MPEG audio is multi-channel digital audio, using lossy compression from original PCM format
with sample rate of 48 kHz at 16 bits. Both MPEG-1 and MPEG-2 formats are supported. The
variable bitrate is 32 kbps to 912 kbps, with 384 being the normal average rate. MPEG-1 is
limited to 384 kbps.

Linear PCM is uncompressed (lossless) digital audio, the same format used on CDs and most
studio masters. It can be sampled at 48 or 96 kHz with 16, 20, or 24 bits/sample. (Audio CD
is limited to 44.1 kHz at 16 bits.) There can be from 1 to 8 channels. The maximum bitrate is

6.144 MBps.

DVD Region Codes

After setting the DVD region (by playing a DVD video for the first time), the DVD region can be
changed four times; after that the DVD drive will only play DVD videos from the last DVD
region that was set.

CD-RW Technology

CD-RW drives use a technology known as optical phase-change. It does not use magnetic fields
like the phase-change technology used with magneto-optical technology. The media are
generally distinguishable from CD-R discs by their metallic grey color. The basic structure of the
discs, however, is the same as a CD-R disc but with significant detail differences. A CD-RW
disc’s phase-change medium consists of a polycarbonate substrate, moulded with a spiral groove
for servo guidance, absolute time information and other data, on to which a stack (usually
five layers) is deposited. The recording layer is sandwiched between dielectric layers that draw
excess heat from the phase-change layer during the writing process. In place of the dye-based
recording layer on a CD-R disc, CD-RW commonly uses a crystalline compound made up of a
mix of silver, indium, antimony and tellurium. This mix, when heated to a certain temperature
and then cooled becomes crystalline, but if heated to a higher temperature it becomes amorphous
when it cools down again. The crystalline areas allow the metallized layer to reflect the laser
light better while the non-crystalline portion absorbs the laser beam, and is therefore not
reflected.

CD-RW devices use three different laser powers to achieve these effects in the recording layer:

countries, Sub-Indian continent

the highest, called ‘Write Power,’ creates a non-crystalline (absorptive) state on the

■

recording layer

the medium, ‘Erase Power,’ melts the recording layer and converts it to a reflective

■

crystalline state

the lowest, ‘Read Power,’ does not alter the state of the recording layer, so it can be used for

■

reading the data.

2–14 Technical Reference Guide

System Features

During writing, a focused ‘Write Power’ laser beam selectively heats areas of the phase-change
material above the melting temperature (500-700º C), so all the atoms in this area can move
rapidly in the liquid state. Then, if cooled sufficiently quickly, the random liquid state is
‘frozen-in’ and the so-called amorphous state is obtained. The amorphous version of the material
shrinks, leaving a pit where the laser dot was written, resulting in a recognizable CD surface.
When an ‘Erase Power’ laser beam heats the phase-change layer to below the melting
temperature but above the crystallization temperature (200º C) for a sufficient time (at least
longer than the minimum crystallization time), the atoms revert back to an ordered state (the
crystalline state). Writing takes place in a single pass of the focused laser beam, sometimes
referred to as 'direct overwriting' and the process can be repeated several thousand times per disc.

Once the data has been burned the amorphous areas reflect less light, enabling a ‘Read Power’
laser beam to detect the difference between the lands and the pits on the disc. One compromise
here is that the disc reflects less light than CD-ROMs or CD-Rs and consequently CD-RW discs
can only be read on CD players that support the new MultiRead specification.

CD-RW drives are dual-function, offering both CD-R and CD-RW recording, so the user can
choose the best media for a particular job.

Although UDF (Universal Disc Format) allows users to drag and drop files to discs, CD-RW is
still not as easy to use as a hard drive. Initially limitations in the UDF standard and associated
driver software meant that when data was deleted from a CD-RW, those areas of the disc were
merely marked for deletion and were not immediately accessible. A disc could be used until all
its capacity was used, but then the entire disc had to be erased to reclaim its storage space using a
'sequential erase' function. In hardware terms erasing a disk is accomplished by heating up the
surface to a lower temperature, but for a longer time, which returns it to the crystalline state.

Evolution of the UDF standard and developments in associated driver software have improved
things considerably, making CD-RW more like hard drives or diskette disks.

Memory Usage with Dynamic Video Memory Technology

At boot time the system BIOS dedicates 8 MB of system memory for graphics display. When
more memory is needed the Intel 845G graphics driver submits a request to the operating system,
the operating system grants the request based upon available system memory. When the
application is closed, the OS will reallocate system memory back for generic use. The quantity of
additional memory which can be allocated for video by the operating system is limited, the limit
depends on the quantity of memory installed on the system and on the driver version (the latest
drivers can be downloaded from the web).

The quantity of system memory allocated by the BIOS and the maximum limit cannot be
modified by the user.

USB 2.0 Connectors

The Compaq Evo D510 e-pc features 6 USB 2.0 connectors (4 rear and 2 front).

USB 2.0 extends the speed of the connection from 12 Mbps on USB 1.1 to 480 Mbps
on USB 2.0, providing an attachment point for next-generation peripherals for use with higher
performance PCs and user applications. USB 2.0 is both forwards and backwards compatible
with USB 1.1 and uses the same cables and connectors as USB 1.1.

Externally, a USB 2.0 system looks no different from a USB 1.1 system except for the
identifying logos:

USB 1.1 Logo

USB 2.0 Logo

USB 1.1’s data rate of 12 Mbps is sufficient for many PC peripherals. These peripherals will
continue to operate with no change in USB 2.0 systems. The higher bandwidth of USB 2.0
permits the use of PC peripherals with wider functionality. The higher bandwidth supports the
most demanding PC user applications, where multiple high-speed peripherals are running
simultaneously. When using a USB hub it is important to make sure that you use a USB 2.0
compliant hub.

USB-to-serial and USB-to-printer adapters are available as optional accessories with the
Evo D510 e-pc. USB-to-serial adapters allow you to connect serial devices through your USB
port, similarly USB-to-printer adapters allow you to connect parallel devices through your

Beep Codes and Error Messages

If the computer powers on but does not start properly, it attempts to report the error in two ways:

It emits a modulated audio signal followed by one or more distinct beeps—this is preboot

■

diagnostics.

It displays an error message on the screen – this is a BIOS error.

■

Pre-Boot Audio Signal and Beeps

Preboot diagnostics is performed by a micro-controller on the system board, which generates
audio signals when an error is encountered. The pre-boot audio signal can be used to identify the
hardware component that needs troubleshooting or replacement:

The modulated audio signal can be interpreted by a support provider equipped with the
Virtual Call Assistant. (For more information about the Virtual Call Assistant, refer to
the Virtual Call Assistant User’s Guide, available at

Beeps Issue/Meaning Resolution

When the power switch is depressed, to activate the computer and there are no faults found, the

✎

computer will start up with no unusual or special sounds. If a fault is found during the start-up,
the computer will generate a series of ringing tones followed by the correct number of beeps
shown in this table that correspond to the fault found.

1 Processor fault 1. Check that processor and heatsink ar properly installed.

2. Replace processor

2 Power supply overload 1. Disconnect all external devices and restart the computer.

If the computer starts correctly, add devices,
one-at-a-time until the overload situation is achieved and
the faulty device is identified.

2. If the computer does not start, disconnect the internal
drives and start the computer. If the computer starts
correctly, add devices, one-at-a-time until the overload
situation is achieved and the faulty device is identified.

3 Memory error 1. Verify that memory modules are properly installed in the

computer.

2. Check that memory modules are the design specified by
Compaq.

3. Try replacing memory modules with other known good
modules.

4 Graphics solution error Replace the system board.

5 Plug and Play

initialization error

Replace the system board.

6 Corrupted ROM BIOS Reflash the ROM BIOS.

7 Defective system board Replace the system board.

Manual Title Variable 4–5

BIOS Overview

Pre-boot diagnostics will only detect codes 3, 4, and 5 after a 15-second time-out.

If you miss the beep code, press and hold the power button for at least five seconds until the
modulated sound is emitted again. This “playback” of the memorized code can also be used to
diagnose an intermittent fault.

Avoid disconnecting the computer’s power cord as this will delete some of the computer’s error

diagnostic information encoded in the modulated audio signal.
