Chapter 2
System Board
This high-performance system board supports the Intel Pentium II
CPU running at speeds ranging from 233 to 400 MHz. Integrated with
the Intel 440BX system controller, which consists of the PCI/AGP
controller and the PCI/ISA IDE accelerator (PIIX4), this system board
combines the new generation of Pentium II power with unmatched
graphics performance.
The PCI/AGP controller host bus interface supports a Pentium II
processor with 66 or 100 MHz bus frequency. It also provides a 72-bit
DRAM that supports synchronous DRAM (SDRAM) DIMMs. The
PCI/AGP controller features an Accelerated Graphics Port (AGP)
interface. Supporting up to 133 MHz data transfer speed, the AGP
interface boosts graphics performance.
The PIIX4 is a multifunction PCI device controller implementing
system functions including PCI IDE, universal serial bus (USB)
host/hub, and enhanced power management. 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 board to allow installation
of either master or slave devices.
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 sockets only support SDRAMtype DIMM.
It also supports two USB (Universal Serial Bus) connectors, and other
standard features such as two UART NS16C550 serial ports, one
enhanced parallel port with an Enhanced Parallel Port (EPP)/Extended
Capabilities Port (ECP) feature, a diskette drive interface, and two
embedded hard disk interfaces.

Memory Upgrade
The three 168-pin sockets onboard support SDRAM-type DIMMs only.
You may install 16-MB, 32-MB, 64-MB, or 128-MB DIMMs for a
maximum 384-MB system memory.
The SDRAM DIMMs should work under 3.3 volts; 5-volt memory
devices are not supported. Memory modules with a timing setting of
66 MHz are defined under unbuffered DIMM specifications, while 100
MHz modules are defined under Intel PC-100 SDRAM specifications.
Do not use both 66 MHz (unbuffered) and
100 MHz (registered) SDRAM together. It
could cause your system to malfunction.
Each of the sockets represents one independent bank. This allows
you to install DIMMs with different capacities to form a configuration.

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. 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 cover, following the directions in the housing
installation manual. Check that the jumpers on the system board
and any expansion boards are set correctly.
3.
If you cannot access a new disk, it may be because your disk is
not properly formatted. Format the disk first using the FDISK and
FORMAT commands.
4.
Check that all connectors and boards are secure.
If you go through these steps 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 3 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.
Before you run Setup, make sure that you have saved all open files.
The system reboots immediately after you exit Setup.

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, Windows 3.x,
Windows 95, and Windows NT 3.5 and above. Other operating
systems require this parameter to be set to Disabled.
Chapter 3 BIOS Utility

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 blocks (multiple
sectors) at a rate of 256 bytes per cycle. To disregard the feature,
change the setting to Disabled.
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.
Hard Disk 32-bit Access
Enabling this parameter improves system performance by allowing the
use of the 32-bit hard disk access. This enhanced IDE feature works
only under DOS, Windows 3.x, Windows 95 or higher, and Novell
NetWare. If your software or hard disk does not support this function,
set this parameter to Disabled .
DMA Transfer Mode
The Ultra DMA and Multi-DMA modes enhance hard disk performance
by increasing the transfer rate. However, besides 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.
CD-ROM Drive DMA Mode
3-14
AcerAltos 500L User’s Guide
Set this parameter to Enabled to enable the DMA mode for the CDROM drive. This improves the system performance since it allows

Internal Cache (CPU Cache)
This parameter enables or disables the first-level or internal memory,
that is, the memory integrated into the CPU. The default setting is
Enabled.
External Cache
This parameter enables or disables the external cache memory. The
external cache is incorporated in the CPU module.
Cache Scheme
This parameter shows the cache scheme status only as Write-back
mode. Write-back updates the cache but not the memory when
there is a write instruction. It updates the memory only when there is
an inconsistency between the cache and the memory.
Memory at 15MB-16MB Reserved for
To prevent memory address conflicts between the system and
expansion boards, reserve this memory range for the use of either the
system or an expansion board.

Memory Parity Mode
This parameter allows you to enable or disable the ECC (Error
Checking and Correction) feature. The ECC feature enables BIOS to
detect and correct data errors. Disable this parameter if you want to
disregard the function.

(PnP) devices installed on your system. Otherwise, select Manual.
Refer to your manual for technical information about the
PCI card.

AcerAltos 500L User’s Guide
PCI Slots
When you set the PCI IRQ Setting parameter to Auto, these
parameters specify the auto-assigned 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.
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 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.
Chapter 3 BIOS Utility
3-37
Some VGA cards have required settings for
this feature. Check your VGA card manual
before setting this parameter.
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.
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.
Set this parameter to Yes only if your operating
system is Windows 95 or higher.
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.
CPU Frequency
This parameter displays your CPU’s speed and bus frequency.
Selecting this option displays the following screen:
3-38
AcerAltos 500L User’s Guide
CPU Frequency
Bus Frequency ................ 66/100 MHz
CPU Multiple ................. [3]
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 makes applications 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). The
bus clock speed is often slower than the CPU clock speed.
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.
