Stingray is a high performance Pentium processor
solution for the industry's most demanding workstation
applications.

Based on the Intel 440FX PCIset, the Stingray supports
the latest advanced processor architecture, the Pentium
II (processor-on-a-cartridge), which provides the speed
and performance necessary to address the most intensive
computational applications. Integrated MMX tech­nology, maximum memory of 1 GByte and up to 512K of
Level 2 cache on the CPU make this board powerful and
feature rich.

The Stingray provides features such as Extended Data
Out (EDO) memory, Error Checking and Correction
(ECC), pipelined-burst level 2 cache, the Award Plug
and Play BIOS and Universal Serial Bus (USB) support.
The USB interface has a maximum bandwidth of 12Mbps
and can connect as many as 127 devices to a host system.
USB supports both standard devices that operate at the
full 12Mbps rate and low-end devices that use only a

1.5Mbps subchannel.

In addition, the Stingray is designed to fit into the most
modern ATX form factor, which allows critical compo­nents such as floppy drive connectors, chassis fan, CPU
and memory to be strategically located so that full length

We know that many experienced people prefer to read as
little of the documentation as possible. If this sounds like
you, here’s the short form to get up and running quickly.

Installing the Stingray

1. Make backup copies of your installation and configu­ration diskettes.

2. Ground yourself to prevent damaging static dis­charge by using an anti-static wrist or ankle strap, or
touch a safely grounded metal object.

3. Remove the Stingray from its packaging.

4. Configure and verify the system board’s jumper set­tings (refer to Jumper Settings in Chapter 2).

5. Install the CPU and the system memory. Be sure to
attach the Retention Mechanism as described in Chap­ter 2.

Configuring the Stingray

Although the Stingray system board is packaged in mate­rials that are designed to protect it from physical damage
and static electricity, it is important to use care while
unpacking the board and setting it up.

Static Electricity

The Stingray is shipped from the factory in an anti-static
bag. To reduce the possibility of damage from static
discharge, it is important to neutralize any static charges
your body may have accumulated before handling the
board.

The best way to do this is to ground yourself using a
special anti-static wrist or ankle strap. If you do not have
an anti-static strap available, touch both of your hands
to a safely grounded object, such as the power supply or
chassis of a computer that is connected to the power
socket. After you have grounded yourself, ground the
Stingray board via one of the solder pads that surround
its mounting holes. When you remove the Stingray from
its packaging, place it on top of the anti-static bag, and
carefully inspect the board for damage which might have
occurred during shipment.

Environment Considerations

Make sure the finished computer system is in an area with
good ventilation. The system should not be in direct
sunlight, near heaters, or exposed to moisture, dust, or
dirt.

Installing the Stingray

Introduction

This chapter explains how to install the Stingray system
board, memory, CPU and peripherals.

WARNING: Before installing or removing any peripherals
or components, make sure you have a clear work space and
that you adhere to all anti-static precautions described in
Chapter 1. Micronics recommends that only trained techni­cians install and configure the system board.

Damage which occurs to the board while adding or removing
peripherals or components may void the warranty. If prob­lems arise while installing peripherals, contact the computer
dealer where you purchased the peripheral or Micronics’
Technical Support Department.

System Memory Support

The flexibility of the Stingray is augmented by its sup­port for EDO, BEDO and FPM DRAM memory and
ECC. The Stingray supports ECC (with 72-bit DIMMs
or 36-bit SIMMs) via the chipset.

EDO memory is designed to keep data available to the
processor for an extended period of time. The EDO
memory support extends the performance of conven­tional DRAM memory. The result is an improvement in
memory-access performance on the Stingray system
board.

Stingray System Board Manual

Chapter 3: Installing the Stingray

Installing the Stingray

Installation of the Stingray system board depends on the
type of case you use. The Stingray is designed for the mini
ATX form factor and must be installed in an ATX chassis.

NOTE: If you are unfamiliar with installing a system board,
Micronics highly recommends that you read the computer user’s
manual or contact your dealer’s technical support department.

Tools Required

Micronics recommends using the following tools to install
the Stingray:

❏ Small Phillips screwdriver
❏ Tweezers or a pair of needle-nose pliers
❏ Tray (to hold loose screws)

Equipment Required

Micronics recommends using the following equipment
with the Stingray for a typical configuration:

❏ ATX chassis with standard hardware.
❏ A high-quality ATX power supply capable of provid-

ing continuous power within a 3 volt range. A power
filter may be used with a noisy AC power source.

❏ PS/2 mouse and compatible keyboard.
❏ Eight ohm speaker.
❏ Standard ribbon cables for internal connections.
❏ Standard power cord (grounded).

Stingray System Board Manual

Chapter 3: Installing the Stingray

System Memory

System memory is necessary to operate the Stingray
system board. The Stingray supports DIMM modules
and/or SIMM modules for a maximum of 1 GByte of
memory. There are two 168-pin 3.3V unbuffered DIMM
sockets. Each DIMM socket provides a 72-bit wide data
path. There are four 72-pin SIMM sockets. Each SIMM
socket provides a 36-bit wide data path.

Support is provided for EDO, BEDO and FPM DRAM
memory. This section list the rules for adding memory to
the Stingray, give some examples of common memory
configurations and show how to physically install the
memory.

Adding Memory

The following is a list of rules to follow when installing
DIMMs and SIMMs. If you follow these rules, your upgrade
should be trouble-free:

❏ Use 70ns or faster DIMMs and SIMMs.

NOTE: For long term reliability, Micronics recommends
using DIMMs with gold-plated contacts and SIMMs with
tin-plated contacts.

❏ SIMM memory modules support FPM and EDO DRAM

memory types. DIMM memory modules support FPM
and EDO (unbuffered) memory types.

❏ Singled-sided and double-sided memory modules are

supported.

❏ The same type and size of memory for every bank

recommended. Different memory types and sizes in
separate banks will cause the performance of the
memory to run at the speed of the slowest RAM
installed.

Configuration

After the Stingray system board and all hardware is in­stalled, the system is ready for configuration. Before turn­ing on the computer, make sure all cables are correctly
connected and all jumpers are correctly set.

We recommend that you keep the computer cover off the
first time you boot the system. This makes it faster and
easier to correct any difficulties that might arise.

Initial Boot Up

Power up the Stingray. If the system does not properly boot,
check all your cables and peripherals for bad connections.
You may also get beep codes or error messages. If this
occurs, consult Appendix B for a guide to possible solu­tions.

After the system properly boots, it is ready to be config­ured. The following information explains the proper
procedures for BIOS configuration.

Setup

The Setup program is used to configure the computer’s
BIOS (Basic Input/Output System). The computer’s
BIOS is responsible for configuring the system board and
providing hardware information to the operating system.
In order for the computer to run properly, run the Setup
procedure after first installing the system board and
whenever you make a hardware change to the system.

Stingray System Board Manual

Chapter 4: The BIOS Setup Utility

Quick Power-On Self-Test

When enabled, this selection will reduce the amount of
time required to run the Power-On Self-Test (POST). A
quick POST skips certain steps. We recommend that you
disable quick POST. The default setting is Disabled.

Boot Sequence

Boot Sequence selects the order in which the system
searches for a boot disk. The default setting is A, C, SCSI.

Swap Floppy Drive

This selection can be set to remap the floppy drives.
When set to Disabled (default), drive A: becomes drive
B: and drive B: becomes drive A:.

Boot Up Floppy Seek

When set to Disabled (default), the BIOS tests (seeks)
floppy drives to determine whether they have 40 or 80
tracks. Drives with 720KB, 1.2MB and 1.44MB capacity
all have 80 tracks. The default setting is Disabled.

Boot Up Numlock Status

Toggle between On and Off to control the state of the
Numlock key when the system boots. When toggled On,
the numeric keypad generates numbers instead of control­ling cursor operations. The default setting is Off.

Gate A20 Option

Gate A20 refers to the way the system addresses memory
above 1MB (extended memory). When set to Fast
(default), the system chipset controls Gate A20. When set
to Normal, a pin in the keyboard controller controls Gate

Stingray System Board Manual

41

Chapter 4: The BIOS Setup Utility

A20. Setting Gate A20 to Fast improves system speed,
particularly with OS/2 and Windows.

Security Option

This selection determines whether the password will be
asked for at every system boot or only when entering into
the Setup (default) program.

PCI/VGA Palette Snoop

Alters the VGA palette setting while graphic signals pass
through the feature connector of the VGA card and are
processed by the MPEG card. Enable this option only if you
have MPEG connections through the VGA feature con­nector; this means you can adjust PCI/VGA palettes. The
default setting is Disabled.

OS Select for DRAM>64MB

This selection allows you to select the amount of memory
installed for your operating system. Select NON-OS2 (de­fault) if your operating system has less than 64MB of
memory or if running a non-OS/2 operating system. If your
operating system has more than 64MB of memory installed,
select the OS2 setting.

Video BIOS Shadow

Enabling this selection allows you to shadow the BIOS on
the video card for faster video performance. Some video
cards do not support video BIOS shadowing. Disable this
option if problems occur.

Auto Configuration

Auto Configuration selects predetermined optimal values
of the chipset parameters. When Disabled, chipset param­eters revert to setup information stored in CMOS. Many
fields in this screen are not available when Auto Configu­ration is Enabled.

DRAM Speed Selection

The value in this field must correspond to the speed of the
DRAM installed in your system. Before changing this selec-

Stingray System Board Manual

43

Chapter 4: The BIOS Setup Utility

tion, verify the speed of the DRAM currently installed. This
value is access speed, so a lower value means a faster
system.

DRAM RAS# Precharge Time

The precharge time is the number of cycles it takes for the
RAS to accumulate its charge before DRAM refresh. If
insufficient time is allowed, refresh may be incomplete and
the DRAM may fail to retain data.

MA Additional Wait State

Selecting Enabled inserts an additional wait state before
the beginning of a memory read. The setting of this param­eter depends on the system board design. Do not change
from the manufacturer’s default setting unless you are
getting memory addressing errors.

Fast RAS# to CAS# Delay

This selection allows you to insert a timing delay between
the CAS and RAS strobe signals, used when DRAM is
written to, read from, or refreshed. Disabled gives faster
performance; and Enabled gives more stable performance.

DRAM Read Burst (B/E/F)

Set the timing for burst-mode reads from DRAM. The
lower the timing numbers, the faster the system addresses
memory

DRAM Write Burst (B/E/F)

Set the timing for burst-mode writes from DRAM. The
lower the timing numbers, the faster the system addresses
memory.

44

Stingray System Board Manual

Chapter 4: The BIOS Setup Utility

ISA Bus Clock

You can set the speed of the AT bus here. The settings are
tied to the speed of the PCI bus. If the PCI bus operates at
33 MHz, a setting of PCICLK/4 (default) would yield an
ISA bus speed of approximately 8 MHz, the standard speed
of the ISA bus. While most devices operate at higher ISA
bus speeds, try a slower bus speed if your ISA device does
not function properly at a high bus speed.

DRAM Refresh Queue

When Enabled, you can queue up to four DRAM refresh
requests, so DRAM can refresh at optimal times.
Disabled makes all refreshes priority requests.

DRAM RAS Only Refresh

An alternate to CAS-before-RAS refresh. Leave
Disabled (default) unless your DRAM requires this older
method of refresh generation.

DRAM ECC/Parity Select

Select Parity, ECC or Disabled, depending on the type of
DRAM installed in your system.

Fast DRAM Refresh

The cache DRAM controller offers two refresh modes,
Normal and Hidden. In both modes, CAS takes place
before RAS but the Normal mode requires a CPU cycle for
each. Alternately, a cycle is eliminated by “hiding” the
CAS refresh in Hidden mode. Not only is the Hidden
mode faster and more efficient, but it also allows the CPU
to maintain the status of the cache even if the system goes
into a power management “suspend” mode.

Stingray System Board Manual

Chapter 4: The BIOS Setup Utility

Read-Around-Write

DRAM optimization feature. If a memory read is addressed
to a location whose latest write is being held in a buffer
before being written to memory, the read is satisfied through
the buffer contents and is not sent to the DRAM.

PCI Burst Write Combine

When this selection is Enabled, the chipset assembles long
PCI bursts from the data held in these buffers.

PCI-To-DRAM Pipeline

DRAM optimization feature. When Enabled, full PCI-to­DRAM write pipelining is enabled. Buffers in the chipset
store data written from the PCI bus to memory. When
Disabled, PCI writes to DRAM are limited to a single
transfer per write cycle.

CPU-To-PCI Write Post

When this field is Enabled, writes from the CPU to the PCI
bus are buffered to compensate for the speed differences
between the CPU and the PCI bus. When Disabled, the
writes are not buffered and the CPU must wait until the
write is complete before starting another write cycle.

CPU-To-PCI IDE Posting

Select Enabled to post write cycles from the CPU to the PCI
IDE interface. IDE accesses are posted in the CPU to PCI
buffers, for cycle optimization.

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM
at F0000h-FFFFFh, resulting in better system performance.
However, if any program writes to this memory area, a
system error may result.

46

Stingray System Board Manual

Chapter 4: The BIOS Setup Utility

Video RAM Cacheable

Selecting Enabled allows caching of the video BIOS ROM
at C0000h to C7FFFh, resulting in better video perfor­mance. However, if any program writes to this memory
area, a system error may result.

8-Bit/16-Bit I/O Recovery Time

The I/O recovery mechanism adds bus clock cycles be­tween PCI-originated I/O cycles to the ISA bus. This delay
takes place because the PCI bus is much faster than the
ISA bus. These two fields let you add recovery time (in bus
clock cycles) for 16-bit and 8-bit I/O.

Memory Hole at 15M-16M

You can reserve this area of system memory for the ISA
adapter ROM. When this area is reserved, it cannot be
cached.

DRAM Fast Leadoff

Select Enabled to shorten the leadoff cycles and optimize
performance.

Passive Release

This selection will enable or disable the CPU to PCI bus
accesses during passive release. When disabled, the arbi­ter only accepts another PCI master access to local DRAM.

Delayed Transaction

When enabled, this selection turns on compliance with
the PCI specification version 2.1 in regards to embedded
32-bit posted write buffer to support delay transaction
cycles. The default setting is Disabled.

Chapter 4: The BIOS Setup Utility

Standby Mode

After the selected period of system inactivity (1 minute to
1 hour), the fixed disk drive and the video shut off while all
other devices still operate at full speed.

Suspend Mode

After the selected period of system inactivity (1 minute to
1 hour), all devices except the CPU shut off.

HDD Power Down

After the selected period of drive inactivity (1 to 15
minutes), the hard disk drive powers down while all other
devices remain active.

Wake-Up Events

You can turn On or Off monitoring of four commonly used
interrupt requests so they do not awaken the system from,
or reset activity timers for, Doze and Standby modes.

For example, if you have a modem on IRQ3, you can turn
On IRQ3 as a wake-up event, so an interrupt from the
modem can wake up the system. Or you may wish to turn
Off IRQ12 (the PS/2) mouse as a wake-up event, so
accidentally brushing the mouse does not awaken the
system. The default wake-up event is keyboard activity.

Power Down and Resume Events

You can disable monitoring of common interrupt requests
so they do not awaken the system from, or reset activity
timers for Suspend mode.

POST Messages

During the Power-On Self Test (POST), the BIOS either
sounds a beep code or displays a message when it detects
a correctable error. Currently the only beep code indi­cates that a video error has occurred and the BIOS
cannot initialize the video screen to display any addi­tional information. The beep code consists of a single
long beep followed by two short beeps.

Updating the System BIOS

The Micronics system boards are designed so that the
BIOS can be reprogrammed using a BIOS file. You can
easily FLASH a BIOS by following the steps below:

1) After downloading the appropriate BIOS file from
our BBS or Website, extract it to a bootable MS­DOS 6.X or Windows 95 diskette.

2) If you are using MS-DOS 6.X, reboot your system
with the bootable diskette in the A: drive. To make
sure a clean DOS environment is loaded, press the
F5 key while "Starting MS-DOS" is displayed. After
the system has rebooted, the cursor will appear at
the A:\> prompt.

3) If you are using Windows 95, press F8 when you see
"Starting MS Windows 95." Select the option "Safe
Mode Command Prompt."

4) Now you can run the FLASH utility from the A:\>
prompt. For example, to update the Stingray to
BIOS version XX, you would type:

If you
encounter
any
problems
during this
process, or
if you have
questions
about the
procedure,
please call
Technical
Support.

A:\>AWDFLASH STNGRYXX.BIN [ENTER]

5) After the FLASH screen appears, select [Y]es to save
the current BIOS or [N]o if you do not want to save
the current BIOS. NOTE: It is recommended that
you save the current BIOS.

6) When prompted, select [Y]es to reprogram the
BIOS.

7) After the update process has completed, you will be
prompted to power off or reset your system. Once
the system reboots, verify that the new BIOS version
appears on the screen. NOTE: After reprogram­ming the BIOS, you may need to enter Setup and
reset your settings.

Stingray System Board Manual

71

Appendix C: Updating the System BIOS

NOTE: If the BIOS is somehow erased or does not seem to
accept the upgrade, you can purchase a new BIOS from
