FeaturesLXA-M

FEATURES

•LXA-M is based on the Pentium

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

II Processor operating at 233 ~ 333

•Designed with Intel’s 82443 LX AGPset.

•Supports up to 384MB of DRAM (minimum of 8 MB) on board

•LXA-M 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 (3) 16 bit ISA slots, (4) 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 LXA-M supports (4) 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

•Includes a PS/2 mouse connector.

•Allows use of a PS/2 or AT keyboard.

•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)

•LXA-M utilizes a Lithium battery which provides environmental protec-

tion and longer battery life.

FeaturesLXA-M

•Supports the Universal Serial Bus (USB) connector. The onboard PIIX4 chip

provides the means for connecting PC peripherals such as; keyboards, joysticks, telephones, and modems.

•Built-in ATX 20-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-in SB-Link Connector.

InstallationLXA-M

Easy Installation Procedure

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

Configure DIP Switch 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 LXA-M supports (3) 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 AGPset. Only EDO and SDRAM are supported.

Figure 2 and T able 1 show several possible memory configurations using both SIMM and DIMM.

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.
