MHz external front side bus frequency. It also provides support for ECC synchronous
DRAM (SDRAM) 168 pin DIMMs.

The PIIX4 is a multifunction PCI device controller implementing system functions
including PCI IDE and universal serial bus (USB) host/hub. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.

The system board utilizes both the ISA and the PCI local bus architecture. Two ISA, five
PCI bus slots (including one PCI/ISA shared slot), and one AGP slot reside on the system
board.

Three memory banks composed of 168-pin dual inline memory module (DIMM) sockets
support a maximum system memory of 384 MB using 128-MB DIMMs.

The system board also supports the USB (Universal Serial Bus) interface, and other
standard features such as two UART NS16C550 serial ports, one enhanced parallel port

will not work properly if you use standard
DIMMs with the higher speed CPUs. All of the
installed DIMMs must have the same
capabilities.

After upgrading the CPU you must run Setup (see
section 2.1) and change the ‘CPU multiple’
parameter to the correct multiplier for your new
CPU (see section 2.10.3).

1.9 Error Messages

Do not continue using the computer if you receive an error message of any type. Note the
message and take corrective action. This section explains the different types of error
messages and corresponding corrective measures.

There are two general types of error messages:

• Software

• System

1.9.1 Software Error Messages

Software error messages are returned by your operating system or application. These
messages typically occur after you boot the operating system or when you run your
applications. If you receive this type of message, consult your application or operating
system manual for help.

1.9.2 System Error Messages

A system error message indicates a problem with the computer itself. A message of this
type normally appears during the power-on self-test, before the operating system prompt
appears.

1.9.3 Correcting Error Conditions

As a general rule, if an error message says "Press F1 to continue," it is caused by a
configuration problem, which can be easily corrected. An equipment malfunction is more
likely to cause a fatal error, i.e., an error that causes complete system failure.

Here are some corrective measures for error conditions:

1. Run Setup (See section 2.1). You must know the correct configuration values for

your system before you enter Setup, which is why you should write them down when
the system is correctly configured. An incorrect configuration is a major cause of
power-on error messages, especially for a new system.

2. Remove the system unit cover (See Chapter 3, System Housing). Check that the

jumpers on the system board and any expansion boards are set correctly (see section

1.3 for system board jumper information).

3. Check that all connectors and boards are securely plugged in.

If you go through the corrective steps above and still receive an error message, the cause
may be an equipment malfunction.

If you are sure that your configuration values are correct and your battery is in good
condition, the problem may lie in a damaged or defective chip.

In either case, contact an authorized service center for assistance.

Chapter 2 BIOS Utility

Most systems are already configured by the manufacturer or the dealer. 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.

If you repeatedly receive Run Setup messages,
the battery may be bad. In this case, the system
cannot retain configuration values in CMOS.
Ask a qualified technician for assistance.

Enhanced IDE Features

Hard Disk Size > 504 MB

When set to Auto, the BIOS utility automatically detects if the installed hard disk supports
the function. If supported, it allows you to use a hard disk with a capacity of more than
504 MB. This is made possible through the Logical Block Address (LBA) mode
translation. However, this enhanced IDE feature works only under DOS and
Windows 3.x, 9x environments. The default setting is Auto.

Hard Disk Block Mode

This function enhances disk performance depending on the hard disk in use. If you set
this parameter to Auto, the BIOS utility automatically detects if the installed hard disk
drive supports the Block Mode function. If supported, it allows data transfer in block
(multiple sectors) at a rate of 256 bytes per cycle. To disregard the feature, change the
setting to Disabled. The default setting is Auto.

AcerPower Minitower (M11E/IDCATX-2) User's Guide

Advanced PIO Mode

When set to Auto, the BIOS utility automatically detects if the installed hard disk supports
the function. If supported, it allows for faster data recovery and read/write timing that
reduces hard disk activity time. This results in better hard disk performance. To
disregard the feature, change the setting to Disabled. The default setting is Auto.

Hard Disk 32-Bit Access

Enabling this parameter improves system performance by allowing the use of 32-bit hard
disk access. This enhanced IDE feature works only under DOS, Windows 3.x, Windows
98, and Novell NetWare. If your software or hard disk does not support this function, set
this parameter to Disabled . The default setting is Enabled.

DMA Transfer Mode

The Ultra DMA and Multi-DMA modes enhance hard disk performance by increasing the
transfer rate. However, in addition to enabling these features in the BIOS Setup, both the
Ultra DMA and Multi-DMA modes require the DMA driver to be loaded. By setting this
parameter to Auto, BIOS automatically sets the appropriate DMA mode for your hard
disk. The default setting is Auto.

CD-ROM Drive DMA Mode

Set this parameter to Enabled to enable the DMA mode for the CD-ROM drive. This
improves system performance since it allows direct memory access to the CD-ROM. To
deactivate the function, set the parameter to Disabled . The default setting is Disabled.

Index

lxxv

PCI Slots

When you set the PCI IRQ Setting parameter to Auto, these parameters specify the auto­assigned interrupt for each of the PCI devices. If you set the PCI IRQ Setting parameter to
Manual, you need to specify the interrupt that you want to assign for each PCI device
installed in your system.

AGP

This item shows the assigned interrupt for the onboard accelerated graphics port (AGP)
controller.

PCI IRQ Sharing

Setting this parameter to Yes allows you to assign the same IRQ to two different devices.
To disable the feature, select No. The default setting is Yes.

If there are no IRQs available to assign for the
remaining device function, we recommend that
you enable this parameter.

VGA Palette Snoop

This parameter permits you to use the palette snooping feature if you installed more than
one VGA card in the system. The default setting is Disabled.

The VGA palette snoop function allows the control palette register (CPR) to manage and
update the VGA RAM DAC (Digital Analog Converter, a color data storage) of each
VGA card installed in the system. The snooping process lets the CPR send a signal to all
the VGA cards so that they can update their individual RAM DACs. The signal goes
through the cards continuously until all RAM DAC data has been updated. This allows
the display of multiple images on the screen.

Some VGA cards have required settings for this
feature. Check your VGA card manual before
setting this parameter.

AcerPower Minitower (M11E/IDCATX-2) User's Guide

Graphics Aperture Size

This parameter determines the effective size of the graphics aperture. Graphics aperture
is the address range that the AGP video and the CPU use to manage graphical objects.
The lowest setting is 8 MB and the highest is 256 MB. The default setting is 64 MB.

Plug and Play OS

When this parameter is set to Yes, BIOS initializes only PnP boot devices such as SCSI
cards. When set to No, BIOS initializes all PnP boot and non-boot devices such as sound
cards. The default setting is Yes.

Reset Resource Assignments

Set this parameter to Yes to avoid IRQ conflict when installing non-PnP or PnP ISA
cards. This clears all resource assignments and allows BIOS to reassign resources to all
installed PnP devices the next time the system boots. After clearing the resource data, the
parameter resets to No. The default setting is No.

2.10.3 CPU Frequency

This parameter displays your CPU’s speed and bus frequency. It also allows you to
specify the CPU frequency multiplier. Selecting this option displays the following screen:

CPU Frequency

Bus Frequency ............... [xx] MHz

CPU Multiple ................ [x]

Processor Speed ............. xxx MHz

Bus Frequency

The bus frequency refers to the speed by which data is transferred between internal
computer components and the CPU or the main memory of the CPU. A fast bus allows
data to be transferred faster, which allows applications to run faster.

CPU Multiple

This parameter sets the Core/bus ratio of your system. The clock speed of the bus does
not necessarily equal the CPU’s (core). This multiplier equals the CPU core frequency
divided by the bus frequency.

Processor Speed

The processor speed is the speed at which a microprocessor executes instructions. Clock
speeds are expressed in megahertz (MHz), with 1 MHz being equal to 1 million cycles per
second. The faster the clock, the more instructions the CPU can execute per second.
