Hardware conflicts occur when two or more peripheral devices attempt to use
the same hardware resources. I/O addresses, interrupts, and DMA channels
are the most common hardware resources used by peripheral devices. For
example, the factory default settings for the MIDI port audio interface are:
Audio Interface
Base I/O
address
MIDI Port
Base I/O
address
Interrupt IRQ 5
8-bit DMA Channel 1
When different peripheral devices use the same hardware resources at the
same time, the devices and/or the system may not function properly. You can
resolve hardware conflicts by ensuring that no devices are configured to use
the same hardware resources. These resources can either be dipswitch or
jumper settings on the peripheral card or software configurable resources.
The Computer Setup selection of your Compaq Utilities allows you to view and
220H
330H
modify the settings for the peripheral devices factory installed in your system.
Refer to the User's Guide for the particular peripheral cards you wish to install
for information on how to view and select their settings.
To resolve hardware conflicts:
1. Change the hardware settings of your audio card or other peripheral card
in your system if the peripheral card is using any settings used by the factoryinstalled devices.
2. If you are unsure of the settings of the peripheral cards, you can isolate
the source of the problem by temporarily removing all cards not
manufactured by Compaq, or resetting the default settings and running
Compaq Utilities. After that, add the cards back one at a time until the card
that is causing the conflict is found.

Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and
structure determine the degree of sensitivity. The following proper packaging
and grounding precautions are necessary to prevent damage:
■ Protect all electrostatic parts and assemblies with conductive or
approved
containers or packaging.
■ Keep electrostatic sensitive parts in their containers until they arrive at
static-free stations.
■ Place items on a grounded surface before removing them from their
container.
■ Always be properly grounded when touching a sensitive component or
assembly.
■ Place reusable electronic-sensitive parts from assemblies in protective
packaging or conductive foam.
Use transporters and conveyors made of antistatic belts and metal roller
bushings. Mechanized equipment used for moving materials must be wired to
be grounded, and proper materials must be selected to avoid static charging.
When grounding is not possible, use an ionizer to dissipate electric charges.
Back to List
Preventing Damage to Drives
To prevent damage to hard drives, use the following precautions:
■ Handle drives gently, using static-guarding techniques.
■ Store drives in the original shipping containers.
■ Avoid dropping drives from any height onto any surface.
■ Handle drives on surfaces that have at least one inch of shockproof
foam.
■ Always place drives PCB assembly side down on the foam.
Back to List
Grounding Methods
The method for grounding must include a wrist strap or a foot strap at a
grounded workstation. When seated, wear a wrist strap connected to a
grounded system. When standing, use footstraps and a grounded floor mat.
To prevent static damage at the workstation, use the following precautions:
■ Cover the workstation with approved static-dissipative material. Provide
a
wrist strap connected to the work surface and properly grounded tools
and
equipment.
■ Use static-dissipative mats, heel straps, or air ionizers to give added
protection.
■ Handle electrostatic-sensitive components, parts, and assemblies by the
case or
PCB laminate. Handle them only at static-free workstations.
■ Avoid contact with pins, leads, or circuitry.
■ Turn off power and input signals before inserting and removing
connectors or test equipment.
■ Use fixtures made of static-safe materials when fixtures must directly
contact dissipative surfaces.
■ Keep work area free of nonconductive materials such as ordinary plastic
assembly aids and Styrofoam.
■ Use field service tools, such as cutters, screwdrivers, and vacuums, that
are conductive.
■ Use a portable field service kit with a static dissipative vinyl pouch that
folds out of a work mat. Also use a wrist strap and a ground cord for the
work surface. Ground the cord to the chassis of the equipment
undergoing test or repair.
Back to List
Grounding Equipment
Use the following equipment to prevent static electricity damage to the unit:
Wrist Straps are flexible straps with a minimum of 1 megohm +/- 10%
resistance
to the ground cords. To provide proper ground, a strap must be worn snug
against the skin. On grounded mats without banana-plug connectors, connect
a wrist strap with alligator clips.
Heelstraps/Toestraps/Bootstraps can be used at standing workstations
and are compatible with most types of boots and shoes. On conductive floors
or dissipative floor mats, use them on both feet with a minimum of 1
megohm resistance between operator and ground. To be effective, the
conductive strips must be worn in contact with the skin.
Back to List
Recommended Materials and Equipment
Other materials and equipment that are recommended for use in preventing
static electricity include:
■ Antistatic tape
■ Antistatic smocks, aprons, or sleeve protectors
■ Conductive bins, and other assembly or soldering aids
■ Conductive foam
■ Conductive tabletop workstations with ground cord of 1 megohm
of resistance
■ Static dissipative table or floor mats with hard tie to ground

Screws
The screws used in these products are not interchangeable. If an
incorrect screw is used during the reassembly process, it could
cause damage to the unit. Compaq strongly recommends that all
screws removed during the disassembly process be kept with the
part that was removed, then returned to their proper locations.
As each subassembly is removed from the
