various information about your system configuration
and stores these information in the DMI pool, which is
a part of the system board's Plug and Play BIOS. DMI,
along with the appropriately networked software, is
designed to make inventory, maintenance and
troubleshooting of computer systems easier. Refer to
chapter 4 for instructions on using the DMI utility.

chapter 2 and “Keyboard/Mouse Power On” in the
Integrated Peripherals section in chapter 3 for more
information.
Important:
• The power button will not function once a
keyboard password has been set in the “KB
Power On Password” field of the Integrated
Peripherals submenu. You must type the
correct password to power-on the system. If
you forgot the password, power-off the system
and remove the battery. Wait for a few seconds
and install it back before powering-on the
system.

to use a USB keyboard or USB mouse to wake up a
system that is in the S3 (STR - Suspend To RAM) state.
Refer to “Jumper Settings for Wake-On-USB Keyboard/
Mouse” in chapter 2 and “USB KB/Mouse Wake-Up From
S3” in the Power Management Setup section in chapter 3
for more information.
Important:
• If you are using the Wake-On-USB Keyboard/
Mouse function for 2 USB ports, the 5VSB
power source of your power supply must
support ≥1.5A.

Hardware Installation
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD workstation
only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a
metal part of the system chassis. If a wrist strap is unavailable,
establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.
2.2 System Memory
Features
• Four RIMM sockets
- Two Direct-RDRAM channels with two RIMMs per channel
• Supports maximum of 32 Direct RDRAM devices per channel
• Supports 128MB to 2GB system memory using 64Mbit,
128Mbit or 256Mbit technology - PC-600 or PC-800 RDRAM
• Supports single-sided or double-sided RIMM
• RIMM with SPD (Serial Presence Detect) data structure will
provide optimal memory operation
• Supports ECC function.
Note:
The illustrations on the following pages are based on the NT70SA/SL system board, which is the board that supports onboard
LAN.
16
Hardware Installation
2.2.1 Important Installation Instructions
Certain rules must be followed when installing RIMM to obtain
optimum system performance.
Rule 1: Before installing or uninstalling a RIMM, power off the system
and unplug the power cord. Make sure the Power/Standby
LED is off.
Rule 2: The four RIMM sockets are divided into 2 banks - bank 0
(RIMM sockets 1 and 2) and bank 1 (RIMM sockets 3 and
4). Bank 0 must be populated first ensuring that RIMM
sockets 1 and 2 are installed with RIMMs. The memory
configuration (speed, number of devices, size and density) of
RIMMs in bank 0 and bank 1 must be identical.
Rule 3: Each bank supports a maximum of 32 devices, therefore, the
2 banks support a maximum of 64 devices.
2
Rule 4: The system board supports ECC or non-ECC RIMM. Use
the same type of RIMM in all sockets.
Rule 5: Due to RDRAM’s signal routing, all RIMM sockets must be
populated with modules. If RIMM sockets 3 and 4 (bank 1)
are not populated with RIMMs, YOU MUST install them with
CRIMMs (Continuity RIMM). This is to avoid breaking the
signal lines which are a serial connection in a RAMBUS
interface and will allow the Direct Rambus Channel to
function properly. If, at any time, you wish to upgrade the
system memory, remove the CRIMMs and replace them with
RIMMs.

Hardware Installation
The CRIMM module included in the system board package looks
similar to the one shown below..
2.2.2 Installing a RIMM
A RIMM simply snaps into a RIMM socket on the system board. Pin
1 of the RIMM must correspond with pin 1 of the socket.
1. Pull the “tabs” which are at the ends of the socket to the side.
2. Position the RIMM above the socket with the “notches” in the
module aligned with the “keys” on the socket.
3. Seat the module vertically into the socket. Make sure it is
completely seated. The tabs will hold the RIMM in place.
