System Features
Main Memory
There are two memory module slots on the system board for installing main
memory. You can install 266MHz DDR-SDRAM modules, these are available in
128, 256 and 512MB memory modules. You can install a maximum of 1GB
(2 x 512MB modules).
DIMM slots
You can only use non-ECC memory modules.
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 instead of the two notches found on SDRAM-DIMMs.

Ultra-ATA/100 Hard Disk 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 FeatureATA, UltraATA/100 allows
host computers to send and receive data at 100MB/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.
Ultra ATA/100 hard drives are 100 percent backwards compatible with Ultra ATA/66, Ultra ATA/33, and
DMA, as well as with existing EIDE/IDE hard drives, CD-ROM drives, and hostsystems.
NOTE
S.M.A.R.T. or Self Monitoring Analysis and Reporting Technology allows the hard disk 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.

All models are supplied with a 3.5-inch floppy disk drive.

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.

System Features
CD-RW devices use three different laser powers to achieve these effects in the recording layer:
•
•
•
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.
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 disk. 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 floppy disks.

Digital Versatile Disk (DVD) Technology
Digital Versatile Disc (DVD) is a medium for the distribution of from 4.7 to 17GB of digital data on a
120-mm (4.75 inch) disc. This huge volume of data (CD-ROMs can store 680MB) 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 17GB 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).
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 6.144MBps.
DVD Region Codes
After setting the DVD region (by playing a DVD video for the first time), the DVD region can be changed
a further four times; after that the DVD drive will only play DVD videos from the last DVD region that
was set.

System Features
Graphics
The Compaq Evo D310 Micro Desktop has an Integrated Intel graphics solution. It also has an AGP slot
where an ATI Radeon 7000 orATI Radeon 7500 graphics card can be installed:
Intel 845G Chipset Integrated Graphics
The Intel 845G chipset offers integrated graphics with Dynamic Video Memory Technology (DVMT).
Some memory (8MB) is reserved at boot time from the main memory; further memory is allocated as
needed.
Key Features
•
•
•
•
•
•
•
•
•
•
Dynamic Video Memory Technology: Ensures most efficient system memory usage for optimal 2D/3D
graphics and system performance
Zone Rendering Technology: Significantly reduces the memory bandwidth by up to 11x which results
in much higher 3D performance
Tiled Memory Addressing: Performs Address Remapping in hardware for all graphics surfaces which
increases page coherency and improves memory efficiency
Dynamic Multi-Context Switcher: Provides deeply pipelined operations in both 2D and 3D allowing
overlapping operations with no need to flush between modes of operation
Intelligent Memory Manager: Fourth generation UMA Memory Manager that provides faster accesses,
adequate burst sizes and smart page closing policies
4x Blit Engine for 2D operations: 256 bit wide Blitter fills at a much greater rate than memory
bandwidth which speeds up operations like drop down menus
Deep Display Buffers: Buffer for screen refreshes which enables higher system performance by
reducing the CPU latency as well as decreasing the total transactions handled by the CPU
Non-blocking and multi-tier cache structures: Dedicated internal caches for textures, colors, Z and
vertices which significantly reduces memory bandwidth and improves core performance
Single-Pass Quad Texture Support: Supports up to blending operations for up to four textures in a
single pass which reduces memory bandwidth requirements and CPU loading
Texture Decompression: Provide up to 8x compression and consequent reduction in bandwidth and
footprint.
Memory Usage with Dynamic Video Memory Technology
At boot time the system BIOS dedicates 8MB of system memory for graphics display. When more memory
is needed the Intel 845 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 D310 Micro Desktop 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 USB 2.0 system looks no different from a USB 1.1 system.
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 2.0 drivers are not preloaded on the software image, they can be downloaded from HP’s Support

HP I/O Port Map (I/O Addresses Used by the System)
Peripheral devices, accessory devices and system controllers are accessed via the system I/O space,
which is not located in system memory space. The 64KB of addressable I/O space comprises 8-bit and 16-
bit registers (called I/O ports) located in the various system components. When installing an accessory
board, ensure that the I/O address space selected is in the free area of the space reserved for accessory
boards (100h to 3FFh).
Although the Setup program can be used to change some of the settings, the following address map is
not completely BIOS dependent, but is determined partly by the operating system. Note that some of the
I/O addresses are allocated dynamically.

Only “I/O-to-memory” and “memory-to-I/O” transfers are allowed. “I/O-to-I/O” and “memory-to-memory”
transfers are disallowed by the hardware configuration.
The system controller supports seven DMA channels, each with a page register used to extend the
addressing range of the channel to 16 MB. The following table summarizes how the DMA channels are
allocated.

BIOS Overview
PCI Interrupt Request Lines
PCI devices generate interrupt requests using up to eight PCI interrupt request lines. PCI interrupts can
be shared; several devices can use the same interrupt. However, optimal system performance is reached
when minimizing the sharing of interrupts.

POST Tests
The POST is executed each time the system is powered on, or a reset is performed. The POST process
verifies the basic functionality of the system components and initializes certain system parameters.
The POST starts by displaying a graphic screen of the Hewlett-Packard logo when the PC is started.
Devices, such as memory and newly installed hard disks, are configured automatically. The user is not
requested to confirm the change. Newly removed hard disks are detected, and the user is prompted to
confirm the new configuration by pressing F4.
NOTE
The POST does not detect when a hard disk drive has been otherwise changed.
During the POST, the BIOS and other ROM data is copied into high-speed shadow RAM. The shadow
RAM is addressed at the same physical location as the original ROM in a manner which is completely
transparent to applications. It therefore appears to behave as very fast ROM. This technique provides
faster access to the system BIOS firmware.
The following table lists the POST checkpoint codes written at the start of each test:

BIOS Overview
HP e-DiagTools Preboot Diagnostics (Beep Codes)
When your PC starts up, its BIOS performs a Power-on Self Test (POST) to test your hardware
configuration for any problems. If a problem is detected during the POST, an error is displayed on your
PC’s monitor.
If, however, your PC is unable to display an error message (for example, when your graphics controller
has failed), it will emit a buzzing sound. This is the e-DiagTools preboot diagnostic. In the event of a
problem with your PC immediately after the buzzing sound, a series of beeps is emitted.
If you hear a series of beeps, you should count them as this will help you detect the cause of the problem.
Number of Beeps
Meaning
• If you hear the buzzing audio signal: system OK
0
• No buzzing audio signal: no power, PC is unplugged, power supply is down or system board has failed.

Processor absent, not correctly connected or processor socket not closed
Power supply is in protected mode1
No memory, bad memory modules, incompatible memory module
Graphics solution problem
PnP/PCI initialization problem
Corrupted BIOS. You need to activate crisis recovery procedure.
Defective system board
1.Typically this is as a result of a system board problem, and not a power supply unit fault.
Note that for Memory (code 3), Video Card (code 4), and PnP/PCI (code 5) errors, e-DiagTools preboot
diagnostic will only detect them after a 15-second timeout.
If you miss the beep code, turn off the PC. Then press the on/off power button for five seconds or more
and listen for the signal again.
The e-DiagTools preboot diagnostics, as well as emitting a beep sequence, also encodes troubleshooting
information (such as the PC model, serial number and failing components) into a coded audio signal.
During a support call, this coded signal can then be decoded by the HP Service Provider to provide
immediate and effective assistance.
