Preface
Before using this information and the product it supports, please read the
following general information.
1. This Service Guide provides you with all technical information relating to
the BASIC CONFIGURATION decided for Acer's "global" product offering.
To better fit local market requirements and enhance product
competitiveness, your regional office MAY have decided to extend the
functionality of a machine (e.g. add-on card, modem, or extra memory
capability). These LOCALIZED FEATURES will NOT be covered in this
generic service guide. In such cases, please contact your regional offices or
the responsible personnel/channel to provide you with further technical
details.
2. Please note WHEN ORDERING FRU PARTS, that you should check the
most up-to-date information available on your regional web or channel. If,
for whatever reason, a part number change is made, it will not be noted in
the printed Service Guide. For ACER-AUTHORIZED SERVICE
PROVIDERS, your Acer office may have a DIFFERENT part number code
to those given in the FRU list of this printed Service Guide. You MUST use
the list provided by your regional Acer office to order FRU parts for repair
and service of customer machines.

System Utilities
The manufacturer or the dealer already configures most systems.
There is no need to run Setup when starting the computer unless you
get a Run Setup message.
The Setup program loads configuration values into the battery-backed nonvolatile
memory called CMOS RAM.
This memory area is not part of the system RAM.
NOTE: If you repeatedly receive Run Setup messages, the battery may be bad/flat.
In this case, the system cannot retain configuration values in CMOS.
Before you run Setup, make sure that you have saved all open files. The system
reboots immediately after you exit Setup.

process. When the message of “Press DEL to enter SETUP” appears on the screen,
press the key of [Delete] to enter the setup menu.
NOTE: If the message disappears before you respond and you still wish to enter
Setup, restart the system by turning it OFF and On. You may also restart the
system by simultaneously pressing [Ctrl+ Alt+ Delete].

Instructions
When the system clock generator pulses,
the extreme values of the pulse generate
excess EMI. Enabling pulse spectrum
spread modulation changes the extreme
values from spikes to flat curves, thus
reducing EMI. This benefit may in some
case be outweighed by problems with
timing-critical devices, such as a
clock-sensitive SCSI device.
Enables or Disables HT Spread Spectrum.
HT is Hyper Transport between CPU and
North Bridge.
This feature controls the availability of the
processor’s SSE and SSE2 instruction sets.
When enabled, the processor’s SSE and

Software applications will not be able to use
those instructions to process multiple data
elements simultaneously. However, the
processor’s MMX instruction set will still
be available for use. It is highly
recommended that you leave this BIOS
feature at the default setting.

The four IDE PIO fields let you set a PIO mode (0-4)
for each of the four IDE devices that the onboard IDE
interface supports. Modes 0 through 4 provide
increased performance. In Auto mode, the system
automatically determines the best mode for each
device.
The Chipset contains a PCI IDE interface with support
for two IDE channels. Select Enabled to activate the
first and/or second IDE interface. Select Disabled to
deactivate an interface, if you install a primary and/or
secondary add-in IDE interface.
UDMA (Ultra DMA) is a DMA data transfer protocol
that utilized ATA transfer protocol that utilizes ATA
commands and the ATA bus to allow DMA commands
to transfer data ata maximum burst rate of 33 MB/s.
When you select Auto in the four IDE UDMA fields (for
each of up to four IDE devices that the internal PCI IDE

This option allows you to enable/disable the feature of

When the motherboard’s clock generator pulses, the
extreme values (spikes) of the pulses create EMI
(Electromagnetic Interference). The spread Spectrum
function reduces the EMI generated by modulating
the pulses so that the spikes of the pulses are reduced
to flatter curves. If you do not have any EMI problem,
leave the setting at Disabled for optimal system
stability and performance. But if you are plagued by
EMI, setting to Enabled for EMI reduction.
Remember to disable Spread Spectrum if you are
overlooking because even a slight jitter can introduce
a temporary boost in clock speed which may just
