Introduction
EP-3VCA2
EP -3 VCA2 Fo r m -Fa c t o r
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.

Pow e r-On /Off (Re m o t e )
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-3VCA2’s
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.

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.

On the basis of bounded functions in I/O chipset, the two serial ports are able to
support the External Modem Ring-in Power ON function. Once users connect the
external modem to COM1 or COM2, the EP-3VCA2 mainboard allows users to turn
on their system through the remote and host's dial-up control.
Exclusive Keyboard Power ON Function
To innovate a unique feature to benefit users, we devoted the easiest and most
convenient way to turn on your system based on the the ATX power supply.
How to work with it
Step 1: Please check JP4 at the position 2-3 after you finished the system
installation.

Step 2: You can enjoy the Keyboard Power ON function (KBPO) by pressing any
key and BUTTON only to turn on your system. Your system will be turned
on automatically, after releasing the keys. To power off you system, you
can use the Soft-OFF function under Windows 95/98.
Notes: Intel ATX version 2.0 specification has recommended you use the power
supply with 0.72A(720mA) in 5.0VSB. With our EP-3VCA2 mainboard,
the 5.0VSB standby power only has to be > = 0.2A (200mA) then you can
enjoy this unique benefit. However, the ATX power supply which is < 0.

3 -6 S TR (S u s p e n d To RAM) Fu n c t io n
The EP-3VCA2 supports the STR power management state by maintaining the
appropriate states on the SDRAM interface signals. The power source must be
kept alive to the SDRAM during STR (ACPI S3). Advanced Configuration
Power Interface (ACPI) provides more Energy Saving Features for operating
systems that support OS such as Instant ON and QuickStartTM function.
1. To enable the ACPI function and use the STR functionally to save your system
energy, you are recommended to confirm the following requirements:
a. In BIOS, please select “ ACPI function: Enable” and “ACPI Suspend Type:
S3(STR)” in the Power Management Setup menu.
b. Then, please type the following before installing the Windows® 98:
{Driver}:> Setup /p j
If the Windows® 98 installed in your system without the parameters above,
please do refer your manual or contact Microsoft for more detail and then
upgrade the system to support ACPI function.
c. Restart your system.
d. Getting in to the “Advanced” of the Power Management icon of Control
Panel, and selecting the “Stand By” in the Power Buttons.
2. Getting start with STR function, please click the START button and choose
Shut Down icon. Then, select the Stand By option in the Shut Down Windows
box to let system go to STR mode.
Here are the differences between STR power saving mode and Green (or
Suspend) mode:
a. It is the most advanced Power Management mode
b. It cuts all the power supplied to peripherals except to Memory - max. power

Award’s ROM BIOS provides a built-in Setup program which allows user to
modify the basic system configuration and hardware parameters. The modified
data will be stored in a battery-backed CMOS, so that data will be retained even
when the power is turned off. In general, the information saved in the CMOS
RAM will stay unchanged unless there is a configuration change in the system,
such as hard drive replacement or a device is added.
It is possible for the CMOS battery to fail, this will cause data loss in the CMOS
only. If this does happen you will need to reconfigure your BIOS settings.
To enter the Setup Program :
Power on the computer and press the <Del> key immediately, this will bring you
into the BIOS CMOS SETUP UTILITY.

) to the item and pressing the ‘Enter’ key. An on-line help message is displayed at
the bottom of the screen as the cursor is moved to various items which provides a
better understanding of each function. When a selection is made, the menu of the
selected item will appear so that the user can modify associated configuration
parameters.

word typed now will clear any previously entered password from CMOS memory.
You will be asked to confirm the password. Type the password again and press
<Enter>. You may also press <Esc> to abort the selection and not enter a password.
To disable a password, just press <Enter> when you are prompted to enter the
password. A message will confirm the password will be disabled. Once the pass-
word is disabled, the system will boot and you can enter Setup freely.
PASSWORD DISABLED.
When a password has been enabled, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any part of
your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to request
a password every time your system is rebooted. This would prevent unauthorized
use of your computer.
You determine when the password is required within the BIOS Features Setup Menu
and its Security option (see Section 3). If the Security option is set to “System”, the
