Introduction EP-3VWM
EP-3VWM Form-Factor
The EP-3VWM is designed with MicroATX form factor - the new industry
standard of chassis. MicroATX 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. MicroATX
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-3VWM 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-3VWM 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-3VWMs
onboard circuit controller) that can be controlled by the operating system such as
Windows® 95/98 or Windows®2000 to shutown the system.

System Memory Configuration
Memory Layout
The EP-3VWM supports (2) PC100 168-pin DIMMs (Dual In-line Memory
Module). The DIMMs is for SDRAM (Synchronized DRAM) only.
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 configuration.

Section 4
AWARD BIOS SETUP
Main Menu
Awards 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.
Figure 1: CMOS Setup Utility

The menu displays all the major selection items. Select the item you need to
reconfigure. The selection is made by moving the cursor (press any direction key
) 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.

You can set either supervisor or user password, or both of then. The differences
between are:
supervisor password : can enter and change the options of the setup menus.
user password : just can only enter but do not have the right to change the
options of the setup menus. When you select this function, the following message
will appear at the center of the screen to assist you in creating a password.
ENTER PASSWORD:
Type the password, up to eight characters in length, and press <Enter>. The password 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 password 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
password will be required both at boot and at entry to Setup. If set to Setup,
prompting only occurs when trying to enter Setup.

your computer, the BIOS configures your system according to the Setup selections stored in CMOS. After saving the values the system is restarted again.
Exit Without Saving
Pressing <Enter> on this item asks for confirmation:
Quit without saving (Y/N)? Y
This allows you to exit Setup without storing in CMOS any change. The previous
