FEATURES

LXR Features:

•LXR is based on the Pentium®II Processor operating at 233 ~ 333 MHz

on Slot 1. The board is configured by an DIP Switch to match your CPU

clock speed.

•Designed with Intel’s 82443 LX (or 82443 EX) AGPset.

•Supports up to 256MB of DRAM (minimum of 8 MB) on board

•LXR will support Error Checking and Correcting (ECC) when using

parity DRAM memory modules. This will detect multiple bit errors and correct

1-bit memory errors.

•Supports (2) 16 bit ISA slots, (3) 32 bit PCI slots, (1) AGP slot and provides

(2) independent high performance PCI IDE interfaces capable of supporting

PIO Mode 3/4 and Ultra DMA 33 devices. The LXR supports (3) PCI

Bus Master slots and a jumperless PCI INT# control scheme which reduces

configuration confusion when plugging in PCI card(s).

•Supports ATAPI (e.g. CD-ROM) devices on both Primary and Secondary IDE

interfaces.

•Designed with Winbond W83977TF Multi I/O: (1) floppy port, (1) parallel port

(EPP, ECP), and (2) serial ports (16550 Fast UART).

Note: Japanese “Floppy 3 mode” is also supported

•Features Award Plug & Play BIOS. With Flash Memory you can always

upgrade to the current BIOS as they are released. (http://www.2themax.com/

please visit our Technical Support section for the latest updates)

•LXR utilizes a Lithium battery which provides environmental protection

and longer battery life.

FeaturesLXR

•Supports the Universal Serial Bus (USB) Header. The onboard PIIX4/PIIX4E

chip provides the means for connecting PC peripherals such as; keyboards,

joysticks, telephones, and modems.

•Built-in ATX 20-pin and AT 12-Pin power supply connector.

•Software power-down when using Windows®95.

•Supports ring-in feature (remote power-on through external modem,

allows system to be turned on remotely.

•Resume by Alarm - Allows your system to turn on at a preselected time.

•Power Loss Recovery - In the event of a power outage your system will

automatically turn itself back on without user intervention.

•Supports CPU Hardware sleep and SMM (System Management Mode).

•Supports Desktop Management Interface (DMI) facilitating the management

of desktop computers, hardware and software components and peripherals,

whether they are stand-alone systems or linked into networks. (option)

•Built-in WOL (Wake-up On LAN) Connector.

• Built-inSB-LinkConnector.

Easy Installation Procedure

The following must be completed before powering on your new system:

Configure DIP Switch and Jumper to match your hardware

Install memory chips

Device Connectors

Configure DIP Switch

2theMax designs all motherboards with a DIP Switch to make your install fast and easy.

The following will describe all of the DIP Switch that you are required to set before

moving on to step 2.

Note: The DIP Switch as depicted as shown (Figure 1) in their correct

physical orientation.

System Memory Configuration

Memory Layout

The LXR supports (2) 168-pin DIMMs (Dual In-line Memory Module). The

DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized

DRAM).

• DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or

120MHz (8ns) bus speed.

• If you use both 50ns and 60ns memory you must configure

your BIOS to read 60ns.

• When using Synchronous DRAM we recommend using the

4 clock variety over the 2 clock.

• Fast Page Mode DRAM (FPM) is not supported by the LX

(or EX) AGPset. Only EDO and SDRAM are supported.

Figure 2 and Table 1 show several possible memory configurations using both SIMM

and DIMM.

Power On/Off - This is connected to the power button on the case.

Using the Soft-Off by Pwr-BTTN feature, you can choose either

Instant Off (turns system off immediately), or 4 sec delay (you need to

hold the button down for 4 seconds before the system turns off). When

the system is in 4 sec delay mode, 2theMax has added a special feature to

make the system go into suspend mode when the button is pressed

momentarily.
