This chapter provides instructions for changing or upgrading
BX2 system hardware.
Static electricity can damage integrated circuits. Before
handling any computer component outside its protective
packaging, use one of these methods to discharge static
electricity in your body:
• After you turn off the main switch on the back of the computer
and remove the chassis cover, touch a metal computer
component (such as the power supply).
or
• Wear a static wrist strap that is connected to a natural earth
ground.
Do not handle add-on cards by their “gold finger” connectors.
Fingers have oils and other contaminants that can prevent
connectors from making an electrical connection, which may
cause errors or other malfunctions. Handle all system
components by their mounting brackets or other edges.

Power LED and keylock
Plug the power LED cable into the 5-pin keylock connector.
Some systems feature a keylock function with a front panel switch for
enabling or disabling the keyboard. Connect the keylock switch to the
5-pin keylock connector on the mainboard.
Reset
When the Reset cable is connected, pushing the Reset button on the
front panel causes the system to restart the boot-up sequence.
Plug the Reset push-button cable intothe 2-pin Reset connector on the
mainboard.
Turbo LED
Connecting the 2-pin turbo LED cable to the corresponding Turbo
LED connector causes the LED to light when the system is in Turbo
mode. (The manufacturer has permanently set this mainboard to
Turbo mode.)
IDE LED
When the IDE LED cable is connected, the LED lights when an IDE
device (a hard disk drive or a CD-ROM) is active.
Connect the 2-pin IDE device LED cable to the corresponding IDE
LED connector on the mainboard.

unbuffered and registered DIMMs, providing support for up to 1GB
of main memory using 8, 16, 32, 64, 128, and 256MB SDRAM
DIMMs. Use 12ns or faster memory for 66MHz CPUs. Use 8ns
(100MHz, PC100-compliant) memory for 100MHz CPUs.
256 MB memory modules are available only on PC-registered
DIMMs.
Install either unbuffered or registered memory modules — not both.
Note
You must install memory modules in the order shown in the following
table.

Installing IDE devices (HDD, CD-ROM) BX2 Systems User’s Handbook
20 Chapter 1. WorkingwithBX2SystemHardware
Installing DIMMs
1. Locate the DIMM slots on the mainboard. (See page 12.)
2. Use both hands to press the DIMM straight down into the DIMM
socket.
When the DIMM is properly seated, the clips of the socket snap in
place to hold the DIMM on either side.
Removing DIMMs
Gently press down both clips on each side of the DIMM to remove the
DIMM.
Installing IDE devices (HDD, CD-ROM)
The mainboard offers two primary and secondary IDE device
connectors (IDE1, IDE2.) It can support up to four high-speed hard
disk drives or CD-ROM drives.
Connect one end of the 40-pin flat cable to the IDE device (HDD or
CD-ROM). Connect the other end to the primary (IDE1) or secondary
(IDE2) directionally keyed IDE connector on the mainboard. (See
page 12.)
