System Board

The V72MA is a high-performance system board that supports the
Pentium processor with MMX (MultiMedia eXtensions) technology.
The MMX feature enables the system to handle multimedia functions
and enhance the performance of 32-bit applications.

The system memory is upgradeable to 256 MB via the onboard two
168-pin DIMM (Double In-line Memory Module) sockets. These
sockets accommodate 8-, 16-, 32-, 64- and 128-MB DIMMs. The
system board may also come with either 0 or 512-KB second-level
cache.

To fully support multimedia functions, the board incorporates a high­performance 3-D video controller with AGP (Accelerated Graphics
Port) feature, 4-MB SGRAM (Synchronous Graphics Random Access
Memory), and a 3-D audio controller.

Onboard I/O (input/output) interfaces are comprised of two UART
(Universal Asynchronous Receiver-Transmitter) 16C550 serial
interfaces (one port and one connector), a parallel port with SPP
(Standard Parallel Port)/ECP (Extended Capabilities Port)/EPP
(Enhanced Parallel Port) support, and PS/2 keyboard and mouse
ports. Two USB (Universal Serial Bus) ports, one VGA (Video
Graphics Accelerator) port, one Feature connector, one Microphone­in port, one Line-in port, one Line-out port, and one Game/MIDI
(Musical Instrument Digital Interface) port are also added to the board
design to enable the system to support additional peripherals.

For expansion, the board comes with one ISA (Industry Standard
Architecture) slot and three PCI (Peripheral Component Interface)
slots.

1.16.3 Correcting Error Conditions

As a general rule, the "Press F1 to continue" error message 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 these values down when the system is correctly configured.
An incorrect Setup configuration is a major cause of power-on
error messages, especially for a new system.

2. Remove the system cover according to the directions in the
system housing installation guide. Check that the system board
and any expansion boards are set correctly.

3. Check that all connectors and boards are secure. Consult the
system housing installation guide for assistance.

If you have purchased a new hard disk drive
and cannot access it, it may be because
your disk is not physically formatted.
Physically format the disk using the FDISK
and FORMAT commands.

If you follow 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. Contact an authorized service center for assistance.

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.

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.

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

BIOS Utility 2-37

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.

Refer to section 1.10.2 for instructions on installing and configuring
ISA cards.
