product and to protect it from overheating, these openings must
not be blocked or covered. The openings should never be
blocked by placing the product on a bed, sofa, rug, or other
similar surface. This product should never be placed near or over
a radiator or heat register, or in a built-in installation unless proper
ventilation is provided.
6. This product should be operated from the type of power indicated
on the marking label. If you are not sure of the type of power
available, consult your dealer or local power company.
7. This product is equipped with a 3-wire grounding-type plug, a plug
having a third (grounding) pin. This plug will only fit into a
grounding-type power outlet. This is a safety feature. If you are
unable to insert the plug into the outlet, contact your electrician to
replace your obsolete outlet. Do not defeat the purpose of the
grounding-type plug.
8. Do not allow anything to rest on the power cord. Do not locate
this product where persons will walk on the cord.
iii
9. If an extension cord is used with this product, make sure that the
total ampere rating of the equipment plugged into the extension
cord does not exceed the extension cord ampere rating. Also,
make sure that the total rating of all products plugged into the wall
outlet does not exceed 15 amperes.
10. Never push objects of any kind into this product through cabinet
slots as they may touch dangerous voltage points or short out
parts that could result in a fire or electric shock. Never spill liquid
of any kind on the product.
11. Do not attempt to service this product yourself, as opening or
removing covers may expose you to dangerous voltage points or
other risks. Refer all servicing to qualified service personnel.
12. Unplug this product from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
a. When the power cord or plug is damaged or frayed
b. If liquid has been spilled into the product
c. If the product has been exposed to rain or water
d. If the product does not operate normally when the operating
instructions are followed. Adjust only those controls that are
covered by the operating instructions since improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the product to normal condition.
e. If the product has been dropped or the cabinet has been
damaged
f. If the product exhibits a distinct change in performance,
indicating a need for service
iv
13. Replace the battery with the same type as the product's battery
we recommend. Use of another battery may present a risk of fire
or explosion. Refer battery replacement to a qualified
serviceman.
14. Warning! The battery could explode if not handled properly. Do
not recharge, disassemble or dispose of it in fire. Keep it away
from children and dispose of any used battery promptly.

System Board
1.1 Features
The M9LD is a dual-processor system board built on an ATX
baseboard that supports the Intel Pentium II CPU processor running
at 266/66 MHz, 300/66 MHz, 333/66 MHz, 350/100 MHz, 400/100
MHz, and future Intel Pentium II processors. It contains an exclusive
connector for the CPU board that carries two slots for the Pentium II
CPU modules.
The host bus interface supports a Pentium II processor with 66 or 100
MHz bus frequency. It also supports synchronous DRAM (SDRAM)
DIMMs.
The M9LD supports PCI IDE, universal serial bus (USB) host/hub,
and enhanced power management. It also supports Ultra DMA/33
synchronous DMA-compatible devices.
A 50-pin Fast SCSI (Small Computer System Interface) and a 68-pin
Wide SCSI comes with the M9LD to connect SCSI devices. Wide
SCSI supports 16-bit transfers while fast SCSI uses a 8-bit bus that
doubles the clock rate to support data rates of 20 Mb/s.
The M9LD system board also supports the USB (Universal Serial
Bus) connector, and other standard features such as two UART
NS16C550 serial ports, one parallel port with Enhanced Parallel Port
(EPP)/Extended Capabilities Port (ECP) features, a diskette drive
interface, and two embedded hard disk interfaces. The board also
includes a built-in 10/100 Mb/s Intel 82557 LAN chip.
System Board 1-1
The system board supports two optional features, ASM Pro and the
remote diagnostic management (RDM), that allow better server
management. ASM Pro detects problems in CPU thermal condition,
CPU working voltage detection (±12V/±5V/3.3V/1.5V), and PCI bus
utilization calculation. It also detects if the CPU fan or the chassis fan
malfunctions. RDM allows execution of the RDM diagnostic program
from a remote RDM station to fix detected problems or to reboot the
system.
This system is fully compatible with MS-DOS V6.X, DOS/V, IBM
OS/2 Warp, Novell Netware, Novel SFT III, SCO UNIX, and Windows
NT.

1.5 ESD Precautions
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
qualified technician.
System Board 1-9
1.6 Video Memory Upgrade
Larger video memory allows you to display higher resolutions and
more colors. The system board comes with a 1-MB video memory
onboard upgradable to 2 MB.
Follow these steps to upgrade the video memory:
1. Locate the video DRAM upgrade sockets labeled U36 and U37
on the system board. See Figure 1-1.
2. Gently insert a video chip into each of the upgrade sockets.
Make sure that the pin 1 indicator on the chip
matches the notched corner of the socket.

1.7 Installing Expansion Cards
1.7.1 Installing a PCI Card
To install PCI cards:
1. Locate the PCI slot(s) on the mainboard.
2. Remove the bracket on the housing opposite to the empty PCI
slot.
3. Insert a PCI card into the slot. Make sure that the card is
properly seated.
4. Secure the card to the housing with a screw.
When you turn on the system, BIOS automatically detects and
assigns resources to the PCI devices.
Figure 1-4 Installing a PCI Card
System Board 1-13
1.7.2 Installing an ISA Card
Both PnP and non-PnP ISA cards require specific IRQs. When
installing ISA cards, make sure that the IRQs required by these cards
are not previously assigned to PCI devices to avoid resource
conflicts.
Follow these steps when installing ISA cards:
1. Remove all PnP cards installed in the system, if any.
