About Genesis MP

The Media-Publishing Workstation for the Next Century

The machine you have before you is the new standard in the com-

puter industry—the DayStar Genesis MP. Now Macintosh users

can have the speed they associate with expensive, high-end work-

stations—but at a reasonable price.

Genesis MP is the fastest Mac OS based system available—the

first Mac OS based computer with speed built-in. Using its exper-

tise in multiprocessing, DayStar created Genesis MP with internal

multiprocessing hardware and software. Adopted by Apple,

DayStar’s nPOWER multiprocessing extensions to the Mac OS

are now the official standard for multiprocessing on the Mac.

As computer software becomes more sophisticated, designers,

illustrators, video editors, animators and multimedia producers will

require a machine that’s fast enough to keep pace with their flow

of ideas. Genesis MP is a Media-Publisher’s dream come true.

First— Genesis MP begins with a fast, upgradable PCI-bus moth-

erboard, featuring 2 SCSI busses, Ethernet, 16-bit stereo sound

and room for ample memory expansion.

Then— DayStar adds its nPOWER scalable multiprocessing tech-

nology, a fast tray-loading CD-ROM drive and a solidly-built tower

case with 10 drive bays, 350 watt power supply and three large

cooling fans for improved system reliability.

At the heart of Genesis MP is nPOWER—DayStar’s upgradable

processor card, which features up to four PowerPC 604 processors.

Since the processors are on a card, Genesis may be upgraded as

faster and more advanced processor technology becomes available.

To allow programs to take advantage of nPOWER’s speed,

DayStar has developed an open multiprocessing API (Application

Programming Interface). The API makes it very easy for program-

mers to add multiprocessing support to applications. The API stan-

dard is available to all interested developers.

Apple has acquired the rights to DayStar’s nPOWER architecture.

With Apple’s commitment, nPOWER (now known as the Apple

Multiprocessing Application Programming Interface) is assured of

software support in future versions of the Macintosh operating sys-

tem. Software developers that provide support for nPOWER include

Adobe, Metrowerks, Strata, Elastic Reality and many others.

Electrostatic Discharge (ESD) Rules

This section covers the proper procedures for grounding and utiliza-

tion of recommended equipment and materials for preventive damage

from Electrostatic Discharge (ESD).

Static electricity can be discharged from one’s self or by a conductor

thereby destroying static-sensitive devices or micro-circuitry. Often,

static discharge may not be detected by sight, touch, or sound,

although damage occurs. Electronic devices exposed to ESD may not

be affected at all and will continue to function properly. Or, this

device(s) may function properly for awhile, then gradually degrade

internally, thus reducing the life of the device(s).

When handling a device consider the following ways static electricity

can be emitted, thereby producing various levels of electrostatic volt-

age levels:

• Working in extreme low humidity

• Walking across carpet with device

• Walking across a vinyl floor

• Body motion within an unprotected ESD work area

• Removing device(s) from plastic packaging

• Removing device(s) from vinyl packaging

• Removing device(s) from Styrofoam packaging

• Removing device(s) from bubble-wrap packaging

• Packing or Unpacking device(s) wrapped in foam

CAUTION

The Genesis MP uses electronic components that are sensitive to

static electricity. Use care when handling and installing these com-

ponents to prevent damage which can be caused by static cur-

rents. Always work in an area of low static electricity on a ground-

ed surface to prevent static discharge.

ESD SAFE WORK AREA

IMPORTANT

Many electronic devices are ESD sensitive. Be sure to take the follow-

ing precautions when handling an electronic device:

• When seated, always wear an Anti-static Wrist Strap

• When standing, wear footstraps on a grounded floor mat

• Never attempt installation on a carpeted floor

• Never wear leather shoes (rubber soles are recommended)

• Never attempt installation in an overly dry environment

• Never wear silk or polyester clothing during an installation

• Always remove all jewelry (i.e., rings, bracelets, watches, etc.)

• Always transport electronic devices in static-safe containers:

(i.e., tubes, bags, boxes)

• Always protect parts and assemblies with conductive ESD

approved containers and/or packaging

• Always remove electronic devices in a grounded work area

• Always use field service tools (i.e., screwdrivers, snips, vac-

uums) that are conductive.

Genesis MP is Shipped Complete with an Anti-Static Wrist Strap

The Anti-static Wrist Strap shipped with the Genesis MP is a one-use

disposable safety strap intended for the customer’s use. If you do not

have a re-usable Anti-static Wrist Strap, be sure to purchase one for

each employee that will be handling, installing, servicing, and/or main-

taining equipment.

Grounding Using The Anti-static Wrist Strap

These straps hold a minimum of 1 megaohm resistance. To ensure

proper grounding, this strap must be worn in direct contact with the

skin.

Grounding Using A Grounding Mat

This mat should be used when standing in an electro-static area and

when handling electronic devices. Alligator clips may be substituted

for banana-plug connectors connected to a wrist strap.

Grounding Using Heelstraps/Toestraps/Bootstraps

These straps can be used when standing. These straps may be sub-

stituted for most shoes or boots. The conductive strips must be worn

in direct contact with the skin to be effective.

PREVENTING DAMAGE TO DISK DRIVES

To prevent ESD and physical shock damage to floppy diskette

drive and/or hard disk drive(s), ensure the following safety precau-

tions:

• Always utilize anti-static techniques when handling drives

• Always re-package drives in their original shipping packaging

• Never drop a drive onto any surface (hard/or soft)

• Shield work surface with a minimum of 1-inch shock-proof foam

• Always place drives “assembly-side-down” on shock-proof foam

CD-ROM Drive

CAUTION

Making adjustments or performing procedures other than those

specified in your equipment’s manual may result in hazardous

exposure.

CAUTION

Do not attempt to disassemble the cabinet containing the laser.

The laser beam used in this product is harmful to the eyes. The

use of optical instruments, such as magnifying lenses, with this

product increases the potential hazard to your eyes. For your safe-

ty, have this equipment serviced only by a DayStar-authorized ser-

vice provider.

If you have an internal DayStar CD-ROM drive in your Genesis

MP, your computer is a Class 1 laser product. The Class 1 label,

located in a user-accessible area, indicates that the drive meets

minimum safety requirements. A service warning label is located in

a service-accessible area.

Lithium Battery

Genesis MP uses a lithium battery to store users’ preferences and

time and date information while the unit is not turned on.

CAUTION

Danger of explosion if battery is incorrectly replaced. Replace only

with the same or equivalent type recommended by the manufac-

turer. Dispose of used batteries according to the manufacturer’s

instructions.

Lithium batteries cannot be recharged, therefore require disposal

when exhausted. In addition to its explosive potential, lithium is

water-reactive. Genesis MP’s lithium battery must be disposed of

as hazardous waste, therefore, DayStar Digital, Inc. recommends

the following battery disposal procedure:

After removing the exhausted lithium battery from the mother-

board, place the battery into a zip-lock wrapper and packaging

provided with the replacement battery. Mark the zip-lock wrapper

DEAD and return it to DayStar Digital, Inc, where it will be dis-

posed of according to EPA guidelines.

Disposal of a used battery should be handled in accordance with

county, state, province, or local battery disposal regulations.

WARNING

NEVER ATTEMPT TO OPEN OR SERVICE A USED BATTERY.

OPENING A BATTERY CAN DAMAGE THE BATTERY AND

EXPOSES POTENTIALLY HARMFUL AND HAZARDOUS COM-

PONENTS INTO THE ENVIRONMENT.

THERE ARE NO SERVICEABLE PARTS LOCATED INSIDE THE

BATTERY.
