Introduction

Welcome to the PCA-6551VE Socket 370 single board computer. It is a half-size FC­PGA Pentium®-based single board computer with VGA and Ethernet.

The PCA-6551VE boosts embedded applications to new heights, especially where
size is a paramount concern. At the same time, it also effectively eliminates the
constraints in performance which exist in most traditional embedded architectures.

The PCA-6551VE has the evergreen Intel 440 BX PCI set built-in. The 440 BX can
support 66 MHz as well as 100 MHz front side bus. All the original Socket 370 based
designs for the Celeron™ CPU running 66 MHz FSB now require major revamping to
reliably run with the advanced Pentium III based Coppermine, even though the
Coppermine uses the same socket. The Pentium® III with FC-PGA package is Intel’s
first high performance CPU which reverts to the socket approach. This makes high
performance in half-size computing possible, and the PCA-6551VE is already the
performance leader.

There are two 168-pin DIMMs reserved on the PCA-6551VE. The total memory
support is 512 MB, which is the largest in its kind. The VGA has an onboard AGP
interface, and the C&T 69000 controller is used. Since the onchip video memory can
be 2 or 4 MB, the graphics/video performance is high enough for most industrial
applications. The Realtek 10/100Base -T Ethernet controller is also onboard. It
operates via a PCI interface, which guarantees high-speed communication. These
onboard devices with high-speed interfaces (either via AGP or PCI) are important
because they must match the power of the Pentium® III.

The PCA-6551VE also has Advantech’s standard SBC features built-in. These
include ISAMAX to support numerous ISA cards typically required for CTI
applications. This makes the PCA-6551VE one of the best and most powerful engines
for a variety of CTI environments. The high-precision RTC with battery is reserved to
guarantee precise timing and scheduling. A socket for DOC® is also reserved for a
solid state disk up to 144 MB. However, due to height constraints, it only supports
up to a 24 MB DOC. Other features such as 2S1P, IDEx1 up to mode 4 performance,
and an FDD connector are also included. We are proud of our PCA-6551VE, which
underscores our contribution to the IPC market. The PCA-6551VE will play a crucial
role in being an IPC master which can react quickly as rapid advances in technologies
occur. The Coppermine based CPU is so sophisticated that it is continuing to
challenge the skills of SBC designers. In future, Advantech will release more and
more products based on this technology.

System Memory and CPU Installation

This chapter explains how you can expand the capability of your CPU board by
changing system memory, cache memory, and/or the CPU.

3.1 System Memory

Your system DRAM is provided by 168-pin DIMMs (Dual Inline Memory
Modules) on the CPU board. The CPU board contains two memory banks
corresponding to connectors DIMM1 and DIMM2.

The table below shows possible DIMM configurations for the memory banks,
and the following figures help you correctly install the DIMM modules. See
Figure 3-2 for the location of the memory banks.

DIMM1 DIMM2 Total Memory

16 MB -- 16 MB
16 MB 16 MB 32 MB
32 MB -- 32 MB
32 MB 32 MB 64 MB

256 MB 256 MB 512 MB

System Memory and CPU Installation 3-1

PCA-6551VE User's Guide

The DIMMs use SDRAM memory. Note that if the 100 MHz CPU external clock
is turned on, the memory should be SDRAM only and PC/100 compliant.

System Memory and CPU Installation 3-2

PCA-6551VE User's Guide

3.2 Cache Memory

The PCA-6551VE does not support external cache memory.
The CPU has an on-die second level (L2) cache.

3.3 Changing the CPU

The PCA-6551VE uses a 321-pin PGA socket rather than a ZIF socket. Thus
some force is required to push the CPU into the socket or pull the CPU out from
the socket. Normally, some tools are required to pull the CPU out from the socket.
To push in a new CPU, place the CPU on the middle of the socket. Make sure
that the beveled corner of the CPU lines up with the beveled corner of the socket.
Then make sure that the pins of the CPU fit evenly over the socket openings.
Push the CPU in until all the pins fit snugly into the socket. Be sure to re ­configure the DIP switch settings for the correct clock and core/bus ratios. The
PCA-6551VE supports many kinds of CPUs. Refer to the DIP switch setting table
for the correct configuration.

Warning: The FC-PGA Pentium® III CPU is fragile. Install and remove it gently.

Using excessive force may result in breakage.

3.4 Installing a CPU Fan

1. Loosen the four screws on the fan to make the frame loose. Then peel off the thin
plastic coating on the rubber pad.

Figure 3-2: Peeling off the thin plastic coating of the CPU fan

System Memory and CPU Installation 3-4

PCA-6551VE User's Guide

2. Lift the frame to the same height as the rubber pad, and make sure that the bevel of
the CPU is positioned at the lower right-hand corner. Push the
Coppermine/Celeron™ forward into the frame. Note that rubber pad should not
obstruct the die on the Coppermine/Celeron.

Figure 3-3: Pushing the Coppermine/Celeron™ into the frame

System Memory and CPU Installation 3-5

PCA-6551VE User's Guide

3. Once the Coppermine/Celeron™ CPU is correctly attached to the fan, place the
assembly on the board, and plug in the fan power cord.

Figure 3-4: Placing the CPU/fan assembly on the board

System Memory and CPU Installation 3-6

PCA-6551VE User's Guide

4. To affix the assembly to the board, screw the four screws back firmly. Do not use
excessive force, which may distort or break the frame. Note that a Celeron™ CPU is
thicker than a Coppermine, so a Celeron will require less screwing back.

Memory

This item refers to display-only memory, which is determined by POST (Power On Self
Test) of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of base (or conventional)
memory installed in the system. The value of the base memory is typically 512
K for systems with 512 K memory installed on the motherboard, or 640 K for
systems with 640 K or more memory installed on the motherboard.

Extended Memory

The BIOS determines how much extended memory is present during the
POST. This is the amount of memory located above 1 MB in the CPU's memory
address map.

Other Memory

This refers to the memory located in the 640 K to 1024 K address space. This
is, memory which can be used for different applications. DOS uses this area to
load device drivers, in order to keep as much base memory free for application
programs. The most common use for this area is Shadow RAM.

Total Memory

System total memory is the sum of basic memory, extended memory, and other

memory.

4.11 Supervisor/User Password Setting

You can set either supervisor or user password, or both. The differences are:

•

supervisor password: Can enter, and change the options of the setup menus

•

user password: Can only enter, but do not have the right to change the options of
the setup menus

When you select this function, the following message will appear at the center of the screen
to assist you in creating a password.

ENTER PASSWORD:

Type in your password, up to eight characters in length, and press <Enter>. The password
typed in will automatically clear any previously entered password from CMOS memory. You
will be asked to confirm the password. Type the password again and press <Enter>. You
may also press <Esc> to abort the selection and not enter a password.

To disable a password, just press <Enter> when you are prompted to enter the password. A
message will confirm that the password has been disabled. Once the password is disabled,
the system will boot and you can enter Setup freely.

PASSWORD DISABLED.

When a password has been enabled, you will be prompted to enter it every time you try to
enter Setup. This prevents an unauthorized person from changing any part of your system
configuration.

Addition ally, when a password is enabled, you can also require the BIOS to request a
password every time your system is rebooted. This would prevent unauthorized use of your
computer.

You determine when the password is required within the BIOS Features Setup Men u and its
Security option (see Section 4). If the Security option is set to “System”, the password will
be required both at boot-up and at entry to Setup. If the Security option is set to “Setup”,
prompting only occurs when trying to enter Setup.

including NORMAL, LBA & LARGE.

If HDD does not support LBA modes, no ‘LBA’option will be shown.
Users can select a mode which is appropriate for them.

(2) HDD Modes

Award BIOS supports 3 HDD modes: NORMAL, LBA, LARGE

NORMAL mode

This is a generic access mode in which neither the BIOS nor the IDE controller will
make any transformations during accessing.

The maximum number of cylinders, head and sectors for NORMAL mode are
1024, 16 and 63 respectively

no. Cyclinders (1024)
x no. Heads ( 16)
x no. Sectors ( 63)
x no. per sector ( 512)
528 Megabytes

If the user sets his HDD to NORMAL mode, the maximum accessible HDD size will be
528 Megabytes, even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode

This is a new HDD accessing method to overcome the 528 Megabyte bottleneck. The
number of cylinders, heads and sectors shown in setup may not be the number
physically contained in the HDD.

During HDD accessing, the IDE controller will transform the logical address described
by the sector, head and cylinder numbers into its own physical address inside the
HDD.

The maximum HDD size supported by LBA mode is 8.4 Gigabytes. This is obtained
according to the following formula:

no. Cyclinders ( 1024)
x no. Heads ( 255)
x no. Sectors ( 63)
x bytes per sector ( 512)

8.4 Gigabytes

Award BIOS Setup 4-33

PCA-6551VE User’s Guide

LARGE mode

This is an extended HDD access mode supported by Award Software.

Some IDE HDDs contain more than 1024 cylinders without LBA support (in
some cases, users do not want LBA). Award BIOS provides another
alternative to support these kinds of HDDs!

Example of LARGE mode:

CYLS. HEADS SECTOR MODE

1120 16 59 NORMAL
560 32 59 LARGE

BIOS “tricks” DOS (or other OSs) into thinking that the number of cylinders is less than
1024, by dividing that number by 2. At the same time, the number of heads is multiplied
by 2. A reverse transformation process will be made inside INT13h in order to access
the right HDD address!

Maximum HDD size:

no. Cyclinders ( 1024)
x no. Heads ( 32)
x no. Sectors ( 63)
x bytes per sector ( 512)
1 Gigabyte

(3) Remarks

To support LBA or LARGE modes of HDDs, there must be some softwareinvolved. All
such software is located in the Award HDD Service Routine (INT 13h). The computer
may fail to access an HDD with LBA (LARGE) mode selected if you are running under
a Operating System which has replaced the whole of INT 13h.

something, it will either sound a beep code or display a message.

If a message is displayed, it will be accompanied by:

PRESS F1 TO CONTINUE, CTRL -ALT-ESC OR DEL TO ENTER SETUP

POST Beep

Currently there is only one beep code in BIOS. This code indicates that a video
error has occurred and that the BIO S cannot initialize the video screen to display
any additional information. This beep code consists of a single long beep followed
by two short beeps.

Error Messages

One or more of the following messages may be displayed if the BIOS detects an
error during POST. This list includes messages for both the ISA and the EISA
BIOS.

CMOS BATTERY HAS FAILED

The CMOS battery is no longer functional. It should be replaced.
