Features
FEATURES
LXA-M Features: · LXA-M is based on the Pentium® II Processor operating at 233 ~ 333
MHz on Slot 1. [. . . ] 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. · 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. · Built-in SB-Link Connector.

Easy Installation Procedure
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. Figure 2 and Table 1 show several possible memory configurations using both SIMM and DIMM.

* SDRAM only supports 8, 16, 32, 64, 128MB DIMM modules. [. . . ] 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.
