EP-3VBM+ Form-Factor

The EP-3VBM+ is designed with Micro-ATX form factor - the new industry
standard of chassis. The Micro-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.
Micro-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, modem, LAN, etc.) to systems. This will help systems integra­tors differentiate their products in the marketplace, and better meet your needs.

• Smaller size promotes a smaller system size.

• I/O shield does not need to be retooled in an ATX 2.01 or later.

The

mainboard should be used in an ATX 2.01 (or later) compliant case.

• A smaller power supply cam be used. High integration on mainboard reduces
the system costs.

ATX
POWER SUPPLY

Power-On/Off (Remote)

The EP-3VBM+ 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-3VBM+ 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-3VBM+’s
onboard circuit controller) that can be controlled by the operating system. Win­dows 95/98 will control this when the user clicks that they are ready to Shutdown
the system.

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 mis-oriented
insertion.
Don’t 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.

Step 3

Close the socket by lowering and locking the
actuation lever.

System Memory Configuration

Memory Layout

The EP-3VBM+ supports (2) 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 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.

External Modem Ring-in Power
ON and Keyboard Power ON
Functions (KBPO)

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-3VBM+ 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 2 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.

Notes: Intel ATX version 2.0 specification has recommended you use the

power supply with 0.72A(720mA) in 5.0VSB. With our EP-3VBM+
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 < 0.2 (200mA) is still applicable to your system by
placed JP4 at the position 1-2 to disable this feature.

AWARD BIOS SETUP

BIOS Instructions

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.

4-10 IDE HDD Auto Detection

The “IDE HDD auto detection” utility is a very useful tool, especially when you
do not know which kind of hard disk type you are using. You can use this utility
to detect the correct disk type installed in the system automatically. But now you
can set HARD DISK TYPE to Auto in the STANDARD CMOS SETUP. You
don’t need the “IDE HDD AUTO DETECTION” utility. The BIOS will Auto­detect the hard disk size and model on display during POST.

Figure 10: IDE HDD Auto Detection

NOTE: HDD Modes

The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NOR­MAL mode

Generic access mode in which neither the BIOS nor the IDE controller will make
any transformations during accessing.

The maximum number of cylinders, head & sectors for NORMAL mode are.

1024, 16 & 63
no. Cylinder (1024)
x no. Head ( 16)
x no. Sector ( 63)

If user set his HDD to NORMAL mode, the maximum accessible HDD size will
be 528 Megabytes even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode: A new HDD accessing method to
overcome the 528 Megabyte bottleneck. The number of cylinders, heads &
sectors shown in setup may not be the number physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical address
described by sector, head & cylinder into its own physical address inside the
HDD. The maximum HDD size supported by LBA mode is 8.4 GigaBytes which
is obtained by the following formula:

no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x bytes per sector ( 512)

8.4 GigaBytes

LARGE mode: Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some

cases, user do not want LBA). The Award BIOS provides another alternative to
support these kinds of LARGE mode.

CYLS HEADS SECTOR MODE

1120 16 59 NORMAL
560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiplied by 2. A
reverse transformation process will be made inside

INT 12h in order to access the right HDD address!
Maximum HDD size:

no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)

1 GigaByte

Note: To support LBA or LARGE mode of HDDs, there must be some

software involved. All the software is located in the Award HDD

Service Routine (INT 13h). It may fail to access a HDD with LBA
(LARGE) mode selected if you are running under an Operating
System which replaces the whole INT 13h.

UNIX operating systems do not support either LBA or LARGE and must utilize
the Standard mode. UNIX can support drives larger than 528MB.

4-11 Save & Exit Setup

The “SAVE & EXIT SETUP” option will bring you back to the boot up proce­dure with all the changes you just recorded in the CMOS RAM.

4-12 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up
procedure without saving any data into CMOS RAM.

All old data in the CMOS will not be destroyed.
