System Board

The V62X is a high-performance system board that utilizes the new
Intel Pentium II processor. This processor has a built-in MMX
(Multi-Media Extensions) technology that makes the system capable of
handling and enhancing the performance of 32-bit applications and
multimedia functions.

The system board supports PnP (Plug-and-Play) and power
management functions. In addition, it also offers the hardware monitor
function. This DMI (Desktop Management Interface) feature enables
you to monitor the system resources of your PC or of systems in a
network.

For expansion, the system board integrates in its design three ISA and
four PCI slots. It also has a SCSI (Small Computer System Interface) /
LAN (Local Area Network) interface to support SCSI devices and
network functions. The six SIMM (Single In-line Memory Module)
sockets on board allow you to upgrade the system memory to a
maximum of 384 MB.

Notice that the board does not come with an external second-level
cache. This is because the second-level cache is already integrated in
the Pentium II CPU card. The CPU card may come with 256-KB or
512-KB second-level cache size.

The board comes with standard I/O interfaces such as two UART
16C550 serial ports, a parallel port with SPP (Standard Parallel
Port)/ECP (Extended Capabilities Port)/EPP (Enhanced Parallel Port)
feature, PS/2 keyboard and mouse ports. The board also includes a
USB (Universal Serial Bus) interface to enable the system to support
additional peripherals.

1-12 User’s Guide

1.7 Memory Configurations

The system board comes with six 72-pin SIMM sockets that allows you
to expand memory to a maximum of 384 MB. The SIMM sockets
support 5V FPM/EDO DRAMs with 4-, 8-, 16-, 32-, and 64-MB
capacities and 60ns (or less) access time. The FPM DRAM is the
standard DRAM type. The EDO DRAM is actually very similar to FPM.
The only difference is that EDO DRAM holds the memory data valid
until the next memory access cycle, that is similar to pipeline effect
and therefore reduces one clock state, while traditional FPM tri-states
the memory output data to start the pre-charge activity.

Table 1-3 lists the possible memory configurations.

1.7.1 Rules for Adding Memory

· Use only one type of SIMM in a given bank.

· You may combine different types of SIMMs for a memory

configuration as long as the SIMMs in each bank are of the
same type.

· Always install SIMMs in pairs. For example, for a total memory of
8 MB, install two 4-MB SIMMs into the sockets marked
SIMM1 and SIMM2 or SIMM3 and SIMM4. You can not use
an 8-MB SIMM alone for an 8-MB memory.

· Always install SIMMs from the outermost socket first. For
example, socket SIMM1 before socket SIMM2, or
socket SIMM3 before socket SIMM4.

· Always remove SIMMs from the innermost socket first. For
example, socket SIMM4 before socket SIMM3, or
socket SIMM2 before socket SIMM1.

1.13.3 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. 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. 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 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 both cases, contact an authorized service center for assistance.

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 running Setup, have the following information ready:

· Diskette drive type The standard type is either a 5.25-inch

1.2-MB or a 3.5-inch 1.44/2.88-MB diskette drive.

· IDE hard disk drive type The drive information is on the label

pasted on your IDE drive or in the documentation supplied by
the vendor.

2.2.5 Enhanced IDE Features

Hard Disk Block Mode

This function enhances disk performance depending on the hard disk
in use. If you set this parameter to Enabled, it allows data transfer in
block (multiple sectors) by increasing the data transfer rate to 256
bytes per cycle. If your system does not boot after enabling this
parameter, this means that your HDD cannot support the function.
Therefore, you must change the setting to Disabled.

Advanced PIO Mode

Enabling this parameter allows for faster data recovery and read/write
timing that reduces hard disk activity time. This results to better hard
disk performance.

To utilize this feature, your hard disk must support the advanced PIO
mode. If not, set this parameter to Disabled. Refer to your hard disk
documentation for information about the advanced PIO mode.

Hard Disk Size > 504 MB

This enhanced IDE feature works only under DOS and Windows 3.x
environment. If enabled, 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. Other operating
systems require this parameter to be set 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 and Novell NetWare. If your
software or hard disk does not support this function, set this parameter
to Disabled .

2-8 User’s Guide

2.2.6 Num Lock After Boot

This parameter allows you to activate the Num Lock function upon
booting. The default setting is Enabled.

2.2.7 Memory Test

the remaining device function, we
recommend that you enable this parameter.

2.4.3 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
have been updated. This allows display of multiple images on the
screen.

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

2-14 User’s Guide

setting this parameter.

2.4.4 Plug & 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.

2.4.5 Reset Resources Assignment

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.

Refer to section 1.9 for instructions on installing and configuring ISA
cards.

IDE Hard Disk Standby Timer

This parameter allows the hard disk to enter standby mode after
inactivity of 1 to 15 minutes, depending on your setting. When you
access the hard disk again, allow 3 to 5 seconds (depending on the
hard disk) for the disk to return to normal speed. Set this parameter to

Off if your hard disk does not support this function.

System Standby Timer

This parameter sets the system to a "fast-on power-saving mode. It
automatically enters into the standby mode after a specified period of
inactivity. Any keyboard or mouse action, or any enabled monitored
activities occurring through the IRQ channels resume system
operation. See section 2.5.2.

System Suspend Timer

This parameter sets the system to the lowest power-saving mode. It
automatically enters into the suspend mode after a specified period of
inactivity.

In suspend mode, the CPU clock stops. Any keyboard or mouse
action, or any enabled monitored activities occurring through the IRQ
channels resume system operation. See section 2.5.2.

2.5.2 Monitored Activities

The IRQ items under this parameter allow you to monitor system
activities occurring through the IRQ channels to determine whether or
not to enter power-saving mode.

For example, if you assign IRQ 3 to a fax/modem and you set this item
to Enabled, any fax/modem activity wakes up the system from
standby mode.
