FEATURES
BXA-M Features:
•BXA-M is based on the Pentium®II or Deschutes Processor operating
at 233 ~ 333MHz (66MHz) or 300 ~ 450MHz (100MHz) on Slot 1. The
board is configured by an Easy-Setting-Single-Jumper (E.S.S.J.) to match
your CPU clock speed.
•Designed with VIA APOLLO PRO 692/596 AGPset.
•Supports up to 768 Mega of DRAM (minimum of 16 MB) on board, You can
use 168-pin DIMM x 3. It will automatically detect Extended Data Output
(EDO) DRAM at 66MHz only or Synchronous DRAM memory (SDRAM)
at 66MHz or 100MHz (please see Section 3-2).
•BXA-M will support Error Checking and Correcting (ECC) when using
paritys 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 BXA-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 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

•BXA-M utilizes a Lithium battery which provides environmental protec-
tion and longer battery life.
•Supports the Universal Serial Bus (USB) connector. The onboard PIIX4E 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. (optional)
•Supports Hot key, Any key or password Keyboard power ON function
(KBPO).
•Supports USDM software to offer motherboard various status on Windows®
95/98, or Windows®NT 4.0/5.0.
•Supports the CPU, PWR and Chassis fan Auto stop in sleep mode.
•Supports the System Power LED (PANEL) blinks in the sleep mode.
•Built-in WOL (Wake On LAN)Connector.
• Built-in SB-LINK Header for Creative Blaster®AWE64D PCI Bus Sound
Card.

Configure Jumpers
2theMax designs all motherboards with the fewest jumpers to make your install fast
and easy.
The following will describe all of the jumpers that you are required to set before
moving on to step 2.
Note: The jumpers as depicted as shown (Figure 1) in their correct physi-
cal orientation.

Note: Based on the implementation of Intel 440BX PCIset, BXA-M is able
to provides two host bus frequencies -- either 66 or 100MHz for Slot1 processor
andmemoryoperating. Automatically, thedefaultisat66MHzoncePentium®II
processor to be mounted onto this motherboard. In case of Deschutes processor, it is
self-adjustedto100MHzwithoutanymanualmodificationrequired. However,no
matterwhatkindofSlot1processoryou installed,itshouldcomewithrightmemory
modulesfornormalandstable operation. For example,ifyouinstall a Deschutes
processor, you should use the SDRAM module with 100MHz based(or above) to
match the CPU speed. Furthermore, one thing you may need to bear in mind,
before the CPU installation, it is anyway our advice to use JP3 and set up right
speed of Slot1 processor at any time. You may feel like to know about AGP
interface,whichalwaysrunsunder66MHzno matter what frequencyofprocessor

System Memory Configuration
Memory Layout
The BXA-M supports (3) 168-pin DIMMs (Dual In-line Memory Module).
The DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized
DRAM). The DIMMs may be installed using just one chip.
•We recommend using SDRAM DIMM can not mixing
with EDO DIMM modules.
• The EDO DIMM only support pentium®II Processor at 66MHz, not
support Deschutes Processor at 100MHz.
• We recommend when installed the 100MHz Deschutes Processor
using DIMM SDRAM must be 125MHz (-8ns) bus speed. If used
100MHz (-10ns) SDRAM may be critical timing for the
motherboard.
• About the “PC/100 SDRAM spec.” information you may visit Inte’s
home page at:
http//developer.intel.com/design/pcisets/memory/index.htm
• DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or
125MHz (-8ns) bus speed.

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.
