FEATURES
3VBA Features:
•3VBA is based on the Mendocino Processor operating at 300 ~
466MHz on PGA370. The board is configured by an ESSJ (Easy-Setting-
Single-Jumper) to match your CPU clock speed.
•Designed with VIA Apollo Pro+ PCIset.
•Supports up to 768MB of DRAM (minimum of 8 MB) on board (please
see Section 3-2).
•3VBA will support Error Checking and Correcting (ECC) when using
parity SDRAM memory modules. This will detect multiple bit errors and
correct 1-bit memory errors.
•Supports (1) 16 bit ISA slots, (4) 32 bit PCI slots, (1) AGP slot, (1) AMR
slot and provides (2) independent high performance PCI IDE interfaces
capable of supporting PIO Mode 3/4 and Ultra DMA 33/66 devices.
The 3VBA 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 on chip 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)
•3VBA utilizes a Lithium battery which provides environmental protec
tion and longer battery life.
Features3VBA

•Supports the (4) Universal Serial Bus (USB) Ports. The onboard
VT82C686A 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®95/98.
•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 outtage your system will
automatically turn itself back on without user intervention.
•Supports CPU Hardware sleep and SMM (System Management Mode).
•Supports Keyboard power ON function (KBPO).
•Built-in WOL (Wake-up On LAN) Connector.
• Built-in AC97 PCI Audio.

Configure DIP Switch
We design this motherboard 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 3VBA 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
125MHz (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, 128, 256MB DIMM modules.

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, we has added a special
feature to make the system go into suspend mode when the button
is pressed momentarily.
