Introduction EP-3VCA2
EP-3VCA2 F orm-Factor
The EP-3VCA2 is designed with ATX form factor - the new industry standard of
chassis. ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees
within the chassis enclosure and a new mounting configuration for the power
supply. With these changes the processor is relocated away from the expansion
slots, allowing them all to hold full length add-in cards. ATX defines a double
height aperture to the rear of the chassis which can be used to host a wide range of
onboard I/O. Only the size and position of this aperture is defined, allowing PC
manufacturers to add new I/O features (e.g.; TV input, TV output, joystick, modem,
LAN, etc.) to systems. This will help systems integrators differentiate their
products in the marketplace, and better meet your needs.
By integrating more I/O down onto the board and better positioning the hard
drive and floppy connectors material cost of cables and add-in cards is
reduced.
By reducing the number of cables and components in the system, manufactur-
ing time and inventory holding costs are reduced and reliability will increase.
By using an optimized power supply, it's possible to reduce cooling costs and
lower acoustical noise. An ATX power supply, which has a side-mounted fan,
allows direct cooling of the processor and add-in cards making a secondary
fan or active heatsink unnecessary in most system applications.

Power-On/Off (Remote)
The EP-3VCA2 has a single 20-pin connector for ATX power supplies. For ATX
power supplies that support the Remote On/Off feature, this should be connected
to the systems front panel for system Power On/Off button. The systems power
On/Off button should be a momentary button that is normally open.
The EP-3VCA2 has been designed with Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off
button, and the other is the "Soft Off" function (coming from the EP-3VCA2s
onboard circuit controller) that can be controlled by the operating system such as
Windows 95/98. System will be turn off automatically after your click the START
button and resume the Shutdown selection.

FEA TURES
EP-3VCA2 F eatures:
EP-3VCA2 is based on the Socket 370 Processors including PPGA & FC-
PGA operating at 300 ~ 800MHz.
Designed with VIA Apollo Pro 133A PCIset.
Supports up to 768MB of DRAM (minimum of 8 MB) on board (please
see Section 3-2).
EP-3VCA2 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 (5) 32 bit PCI slots, (1) 4X 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 EP-3VCA2 supports (5)
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.epox.com/
please visit our Technical Support section for the latest updates).
EP-3VCA2 utilizes a Lithium battery which provides environmental
protection and longer battery life.

CPU Insertion
CPU Insertion: (use CuMineTM for reference)
Step 1
Open the socket by raising the actuation
lever.
Figure 2
Figure 3
Step 2
Insert the processor.
Ensure proper pin 1 orientation by aligning
the FC-PGA corner marking with the
socket corner closest to the actuation arm
tip. The pin field is keyed to prevent misoriented insertion.
Dont force processor into socket. If it does
not go in easily, check for mis-orientation and
debris.
Make sure the processor is fully inserted
into the socket on all sides.
Page 3-3
Installation EP-3VCA2
Step 3
Close the socket by lowering and
locking the actuation lever.

System Memory Configuration
Memory Layout
The EP-3VCA2 supports (3) PC133 168-pin DIMMs (Dual In-line Memory
Module). The DIMMs is for 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 6 and Table 1 show several possible memory configurations using both
SIMM and DIMM.

* SDRAM only supports 8, 16, 32, 64, 128, 256MB DIMM modules.
* We recommend to use PC100 Memory Module for bus speed between 66MHz
and 100MHz and PC133 Memory for bus speed over 100MHz.
* Using non-compliant memory with higher bus speed (over clocking) may
severely compromise the integrity of the system.

DIMM Module Installation
Figure 7 displays the notch marks and what they should look like on your DIMM
memory module.
DIMMs have 168-pins and two notches that will match with the onboard DIMM
socket. DIMM modules are installed by placing the chip firmly into the socket at a
90 degree angle and pressing straight down (figure 8) until it fits tightly into the
DIMM socket (figure 9).
