FEATURES
MVP4A Features:
• Intel Pentium
®
Processor, Pentium Processor with MMX technology, AMD
K5/K6, Cyrix 6x86L/6x86MX & idt C6 operating at 133 ~ 450 MHz with
321 ZIF socket 7 provides scalability to accept faster Processors in the
future.
• Designed with VIA MVP4 AGPset.
• Supports up to 384 MB 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.
• Supports (2) 16 bit ISA slots, (4) 32 bit PCI slots, and provides (2) independent
high performance PCI IDE interfaces capable of supporting PIO Mode 3/4
and Ultra DMA 33/66 devices. The MVP4A 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 lntegrated 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 T echnical Support section for the latest updates).
• MVP4A utilizes a Lithium battery which provides environmental protection
and longer battery life.
• Software power-down when using Windows
®
95/98.
• Supports ring-in feature (remote power-on through external modem,
allows system to be turned on remotely).

• Supports Keyboard power ON function (KBPO).
• Supports USDM software to offer motherboard various status.
• Supports the CPU and Chassis fan Auto stop in sleep mode.
• Built-in WOL (W ake On Lan) Connector.
• Built-in Sound Blaster compatible/DirectSound AC97 Audio.
• Built-in AGP 2D/3D Graphics Accelerator.

Configure Jumpers
We design this motherboard 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 physical
orientation.

System Memory Configuration
Memory Layout
The MVP4A 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.
• W e r ecommend using SDRAM DIMM can not mixing
with EDO DIMM modules.
• DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or
125MHz (-8ns) bus speed.
• No Registered DIMM support.
Figure 2 and T able 1 show several possible memory configurations using
* SDRAM only supports 8, 16, 32, 64, 128MB DIMM modules.
* We recommend to use PC100 Memory Module for bus speed between 100MHz
and 66MHZ.

Device Connectors (continued)
(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, there is a special feature
to make the system to go into suspend mode when the button is
pressed momentarily.)
