EP-V370Y Form-Factor

The EP-V370Y is designed with MicroATX form factor - the new industry standard
of chassis. The 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.

• Smaller size promotes a smaller system size.

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

be used in an ATX 2.01-compliant.

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

system costs.

Power-On/Off (Remote)

The EP-V370Y has a single 20-pin connector for MicroATX power supplies. For
MicroATX/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-V370Y 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 the
button, and the other is the "Soft Off" function (coming from the EP-V370Y’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.

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-V370Y 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 JP13 at the position 1-2 after you finished the system

installation.

Step 2:Push the momentary switch (J3 PW-ON) to turn on your system and then
push again to hold for more than 4 seconds to turn it off affter counting
memory as soon as you turn it on.

Step 3:You can enjoy the Keyboard Power ON function (KBPO) by pressing any 1

key, Hot key (Ctrl-F1, F2.....F12), Password (A maximum of 5 characters

can be entered.) and BUTTON only to turn on your system. Please refer to
the BIOS Integrated peripherals setup for detail (Page 4-19). The BIOS
Default is keyboard Hot key <Ctrl> - <F1> to turn on the system. Your

system will be turned on automatically, after releasing the keys. To power off

Notes:

1.Intel ATX version 2.0 specification has recommended you use the
power supply with 0.72A(720mA) in 5.0VSB. With our EP-V370Y
mainboard, the 5.0VSB standby power only has to be > = 0.1A

(100mA) then you can enjoy this unique benefit. However, the ATX

power supply which is < 0.1 (100mA) is still applicable to your system

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.

528 Megabytes

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 3 2 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

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.

Interleave: Select the interleave number of the hard disk drive you wish to perform
a low level format on. You may select from 1 to 8. Check the documentation that
came with the drive for the correct interleave number, or select 0 for automatic
detection.

CPU Clock Frequency Selection In BIOS Setting.

There is a special function for CPU over-clocking requirement which can be chosen and set
by BIOS or set by JP5(The undocumented jumper setting from 75MHz to 83MHz or 103MHz
to 133MHz), please refer to the following steps for adjustment.
1 .Enter the BIOS CMOS setup program. (If your system was operated at 66MHz)

2. Choose “Chipset Features Setup” in main menu.

3. Move Cursor to “CPU HOST Clock:Default” item.

4. Use “Page down” (or+) / “Page up (or -) to choose CPU clock frequency as one of 66.8,
75MHz and 83.3MHz.
(Note: There are 66.8, 75 and 83.3MHz for 66MHz CPU CLOCK frequency show, there are

103, 112, 124 and 133MHz for 100MHz CPU Clock frequency show).

5 .Press “Save & Exit setup” to complete BIOS setting.

If the screen becomes blank or the system locks up after above Setting, which means the CPU
you are using is unable to over clock.
Please refer to the followings to recover the CPU clock frequency.

Step 1: Power the system off. (J3 PW-ON)

Step 2: Power the system on again. And then, you will find the message of “CPU over-

clocking fail previously. Please setup” CPU host clock again” is shown during the
BIOS post section. You may press “F1” key to make the CPU frequency as the same as
JP5 setting (either 66MHz or 100MHz), or press “enter” key to set the host frequency
to meet your CPU in the BIOS setting.

W arning:

We do not guarantee all CPUs can be over-clocked (When the undocumented set by BIOS[75
and 83.3MHz] or by JP5[103 to 133MHz]), it depends on CPU design and the peripherals you
are using; it’s vitally important to use faster peripherals (faster SDRAM, AGP, I/O card...) to
come with the higher CPU clock frequency.
Please set apporpriate CPU CLOCK frequency to make the system stable.
