System Board
The V55LA-2 is a high-performance system board with a 64-bit
architecture. It supports the Intel P54C and P55C CPUs running at
75/90/100/120/133/150/166/200 MHz. It also supports Cyrix M1/M2
and AMD K5/K6 CPUs. The system board utilizes the Peripheral
Component Interconnect (PCI) local bus architecture that maximizes
the system performance by enabling high-speed peripherals to matc h
the speed of the microprocessor with its 120 MB or 132 MB per
second transfer rate in burst mode.
The board incorporates a Sound Blaster Pro-compatible audio
subsystem that consists of CD-audio, WaveTable, and fax/modem
line-in interfaces.
A standard 1-MB video DRAM comes onboard and is upgradable up to
2 MB. T wo DRAM banks compos ed of four 72-pin s ockets com e with
the board to support single- and double-density SIMMs for a m aximum
system memory of 128 MB. The SIMM sockets accommodate both
the standard page mode and extended data output (EDO) type
SIMMs. The board supports 256-KB or 512- KB pipeline burst sec ondlevel cache.
The system board includes a 188-pin connector f or the slot board that
contains the PCI and ISA bus slots. The two onboard PCI- enhanced
IDE interfaces with a zero-wait state and 16.6 MB per second trans fer
rate support up to four IDE devices. Onboar d I/O interfaces c omprise
of two UART 16550 serial ports, a parallel port with ECP/EPP feature,
and PS/2 keyboard and mouse ports.

Always observe the following electrostatic discharge (ESD)
precautions before installing a system component:
1. Do not remove a component from its antistatic packaging until
you are ready to install it.
2. Wear a wrist grounding strap before handling electronic
components. Wrist grounding straps are available at most
electronic component stores.
Do not attempt the procedures described in
the following sections unless you are a

1.4.1 Installing a SIMM
Follow these steps to install a SIMM:
1. Carefully slip a SIMM at a 45° angle into a socket making sure
that the curved edge indicating the pin 1 of the SIMM matches
pin 1 of the socket.
A SIMM fits only in one direction. If you slip
in a SIMM but would not completely fit, you
may have inserted it the wrong way. Reverse
the orientation of the SIMM.
2. Gently push the SIMM to a vertical position until the pegs of the
socket slip into the holes on the SIMM, and the holding clips lock
the SIMM into position. The SIMM should be at a 90° angle when
installed.

1.10.2 QuickStart Mode Operation
At any time while the system is running, enter the Quick Start mode by
simply pressing the power switch for less the four seconds. This
action causes the system to rest (Q uickStar t state 1) by turning off the
keyboard, mouse, and monitor. After the specified time in the
QuickStart State Timer parameter in BIOS, the system sleeps
(QuickStart state 2) and turns off the hard disk.
Once the system enters Quick Star t mode, the hard disk/mess age LED
and keyboard LED go off, while the power and monitor LEDs start
blinking.
When a mess age comes, the hard disk/message LED star ts blinking
orange, then green when the hard disk reads the message. After
getting the message, the hard disk and the LED go off again.
Press the power switch again for less than f our seconds to return to
the normal mode.
To enter or exit the QuickStart mode, make
sure to press the power switch within four
seconds. Pressing it for more than four
seconds turns off the system.

manual for help.
1.12.2 System Error Messages
A system error message indicates a pr oblem with the computer itself .

1.12.3 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 m ay be because your disk is
not properly formatted. Format the disk fir st 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.
