This mainboard requires correct configuration information; otherwise,
a malfunction may result.
Static elticity can cause serious damage to integra-
ted circuit mainboards. To avoid building up a static
electric charging on your body, be sure you discharge
any static electricity by grounding yourself before
handling the mainboards. If mainboards are handed
from one person to another, they should touch hands
first, then pass the mainboards.
Information presented in this publication has been carefully checked
for reliability; however, no responsibility is assumed for inaccuracies.
The information contained in this document is subject to change with-

1 Introduction
CB6lX-LX mainboard intergrates the latest advances in processor,
memory, and I/O technologies into mini ATX form factor that
combines performance, flexibility, and easy of use into’high integrated
capable of a variety of price/performance Ievels.
CB6lX-LX mainboard supports Intel Pentium II processor based on the
Intel 440LX PCI set(82443LX and 82371AB), ITE IT8679F Super I/O
Chip. Three standard 168.pin DIMM with memoly size up to 384M8
support Fast Page mode, ED0 and Synchronous DRAM memory.
The Intel 82371AB FYI/IDE XceIerator(PIIX 4) provides and integrated
Bus Master IDE controller with high performance IDE interfaces for up
to four deviCes.
CB61X-LX supports two low cost universal Serial Bus(USB) ports to fit
today and tomorrow’s requirement.

2 Installation
This chapter provides information on how to install and configure
CB61X-LX Mainboard.
The standard packing of CB61X-LX should include:
q CB61X-LX mainboard
m 1 IDE cable
q 1 Floppy cable
a CB61X-LX User’ sManual
a Device driver diskette
CB61X-LX accepts a maximum of 384MB memory size with Fast Page
Mode or Extended Data Output (EDO) memory 01 synchronous
DRAM(SDRAM). The on-board DRAM is installed with 168-pin
DIMM. (Dual-In-line-Memory Module)
CB61X-LX also provides a DIMM plug-and-play support via Serial
PD(Presence Detect) mechanism supported via the NIX4 SMB
interface. CB61X-LX provides optional data integrity features including
EC or ECC in the memory array.
The DIMM Socket is in compliance with JEDEC specifications for 3.3V
unbuffered EDO/SDRAM Module. A DIMM connector is provided to
support up to 385MB EDO/Synchronous DRAM.

How to do the Combination ?
Users can install the DIMM module on any bank according to the
memory configuration table. The possible combinations will make the
total memory size from minimum SMB to maximum 384MB.
