2-1 Mainboard Layout
This mainboard is designed with VIA Apollo MVP3 AGP/PCIset chipset which is
developed by VIA Corporation to fully support Pentium Processor PCI/ISA system.
By providing a massive increase in the bandwidth available between the video card
and the processor (66MHz), the unique feature of AGP supported by VIA Apollo
MVP3 chipset improves the speed of rendering and texturing for 3D graphics.The
chipset also provides an integrated IDE controller with two high performance IDE
interfaces for up to four IDE devices (hard devices, CD-ROM device, etc). The
Winbond W83877TF Super I/O controller provides the standard PC I/O function:
one floppy interface, two 16 Byte FIFO serial ports and one EPP/ECP capable parallel
port. This mainboard layout is shown in the next page for user's reference. Care must
be taken when inserting memory modules, CPUs or even plugging PCI card into
associated slots to avoid damaging any circuits or sockets on board. A cooling fan is
strongly recommended when installing Pentium/Pentium MMX/K5/K6/6x86/6x86L/
6x86MX/C6 processor due to possible overheat.
This mainboard supports a minimum of 8MB and a maximum of 256MB of System
Memory while Onboard 512KB cache to increase system performance.
This mainboard supports standard Fast Page, EDO (Extended Data Out or Hyper
Page Mode) or synchronous DRAM. This mainboard provides two 168-pin DIMM
sites for memory expansion. The sockets support 1M x 64(8MB), 2M x 64(16MB), 4M
x 64(32MB), and 8M x 64(64MB) single-sided or double-sided memory modules. The
memory timing requires 70 ns Fast page devices or 60 ns EDO DRAM. (DRAM
Modules may be parity [x 36] or non-parity [x 32].
This mainboard supports two Onboard PCI IDE connectors, and automatically
detects IDE harddisk type by BIOS utility automatic.
This mainboard supports Award Plug & Play BIOS for the ISA and PCI cards. The
BIOS can be located in Flash EPROM which can replace BIOS code easily if
necessary.
This Mainboard supports YAMAHA YMF715-S Audio interface onboard.

This mainboard supports 2 kinds of powerful and flexible SDRAM frequency
selections. These can be synchronous with CPU bus clock or fixed as 66MHz. By
implementing the VCS (Virtual Clock Synchronization) technology, this mainboard
refers to the use of delay-lock-loop (DLL) to enable synchronous and pseudosynchronous operation of the processor and DRAM, AGP and PCI buses. The JP5
allows user to set the SDRAM Frequency between 66/100MHz.

1
SDRAM Clock Selection
1-2 : Fixed as 66MHz
2-3 : SDRAM Clock = CPU Bus Clcok
Jumper's position:
1-2 : Pseudo-synchronous Status(Fixed as 66MHz)
A more stable and compatible operation condition for non-100MHz based SDRAM
when you are using 100MHz based CPU. This setting is suitable for those users who
are like to remain the usage of current SDRAM module.
2-3 : Synchronous Status(SDRAM Clock= CPU Bus Clock)
Increasing the bus speeds from the traditional 66MHz to 100MHz greatly improves
system performance because the speed at which data traveling between the CPU and
memory is increased by 50%. However, there is one thing you should bear in mind.
Please make sure you are using 125MHz(-8) based or above SDRAM module.

EP-51MVP3F-A
2-4 ATX Power ON/OFF Control
This mainboard equips an ATX power connector which is a single 20-PIN input
device for an ATX power supply (see Figure 2-2). An ATX power supply provides a
build-in Remote Power ON/OFF function. To implement the function, a momentary
switch which is normally open should be connected to the position J3(PIN 12, 13) as
the system's power ON/OFF button. Note that an AT power supply does not offer
this function.
Based on the ATX power connector, this mainboard has been designed to support
both ACPI and Soft-OFF functions. According to the definition of ACPI, a Suspend
mode will be enabled while you push the J3(system power ON/OFF) button less
than 4 seconds. Nevertheless, the system will be turned off by pressing for more
than 4 seconds. Regarding the Soft-OFF(coming from this mainboard onboard circuit
controller), it is another way to turn off your system. Your system can be shut down
automatically by an operation system such as Windows 95.

CHAPTER 3
AWARD BIOS SETUP
Award's ROM BIOS provides a built-in setup program which allows user to modify the
basic system configurations and hardware parameters. The modified data will be stored
in a battery-backed CMOS RAM so that data will be retained even when the power is
turned off. In general, the information saved in the CMOS RAM stays unchanged unless
there is a configuration change in the system, such as a hard drive replacement or a new
device installation.
If this does happen, you will need to reconfigure your configuration parameter.

mode. Refer to item B shown below.
3-10
CHAPTER 3
B. Time-out parameters :
HDD Standby
HDD Standby timer can be set from 1 to 15 minute(s).
System Doze
The "System Doze" mode timer starts to count when there is no "PM events"
occurred. The valid time-out setting is from 1 minute up to 1 hour.
System Suspend
This function works only when the Pentium Procssor is installed. The timer starts
to count when "System Standby" mode timer is timed out and no "PM Events"
occurred. Valid range is from 1 minute up to 1 hour.
3-3-2 Description of the Green Functions
This mainboard supports HDD Power Down, Doze and Suspend power saving functions.
In addition, the hardware suspend function is supported when the J3(12,13) (Refer
to Figure2-1) is closed to enter the Suspend function.
The detailed description of these functions is provided in the next page.
PM Control by APM
If Advanced Power Management(APM) is installed on your system, selecting Yes
gives better power savings.
Video Off Method
Determines the manner in which the monitor is blanked.
V/HSYNC+Blank: System turns off vertical and horizontal synchronization ports and
writes blanks to the video buffer.
DPMS Support: Select this option if your monitor supports the Display Power
Management Signaling (DPMS) standard of the Video Electronics
Standards Association (VESA). USE the software supplied for
your video subsystem to select video power management values.
Blank Screen:
System only writes blanks to the video buffer.
Video off Option
Determines when to activate the video off feature for monitor power management.
The settings are Video off after Suspend/standby/Doze/(N/A).
Soft-off by PWRBTN
This field is for the soft-off function setting. When the board utilizes an ATX power
supply, two types of settings are offered: Delay 4 Sec. and instant-off. When the
setting is Delay 4 Sec., users can power off the system bypressing POWER-ON
button(J3) for 4 seconds. However, if users press POWER-ON button for less than 4
seconds, thesystem will enter the Suspend Mode. When the setting is instant-off,
users' first press on POWER-ON button will power off the system, but the second
press will power on the system.
AWARD BIOS

This field is to set the time that you need the system to turn on. The default value
is 08:00:00.
HDDStandbyMode
When system stops reading or wiriting HDD, the timer starts to count. The system
will cut off the HDD power when timer runs out of time. The system will not resume
operation until either a read from or a wirte to HDD command is executed again.
Doze Mode
The system hardware will drop down CPU clock from nomal working speed
when Doze mode time-out occurs.
Suspend Mode
When the system suspend timer times out, the system will enter the suspend mode
and the chipset will stop CPU clock immediately. The power consumption in
Suspend Mode is lower than in standby mode. The screen is also blanked out.
3-12
CHAPTER 3
PMEvents:
AWARD BIOS defines 7 PM Events in the power management mode (Doze &
suspend). The user can initialize any PM Events to be "Enable" or "Disable".
When the system detects all of the enabled events do not have any activity, it will
start the system Doze timer first if the "Power Management" is not "Disabled". Once
the system Doze timer is timed out, it will process doze power saving procedure
by starting the system suspend timer. When the suspend timer times out , all of the CPU
clock will stop by dropping system clock down to zero and remains this way
until any one of the "Enabled" event occurrs.

If an user sets the HDD to NORMAL mode, the maximum accessible HDD size
will be 528 Megabytes even though its physical size may be greater than that!
AWARD BIOS
3-19
LBA (Logical Block Addressing) mode: This is a new HDD accessing method to
overcome the 528 Megabyte bottleneck.
The number of cylinders, heads and sectors shown in the setup may not be the number
physically contained in the HDD.
During the HDD accessing, the IDE controller will transform the logical address
described by sector, head and 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. Cyclinder
(1024)
x no. Head
( 255)
x no. Sector
( 63)
x bytes per secttor
( 512)
8.4 Gigabytes
LARGE mode: This is an extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinders without LBA support (in some
cases, user does not want LBA). The Award BIOS provides another alternative to
support these kinds of LARGE mode:

CHAPTER 3
Note:
To support LBA or LARGE mode of HDDs, there must be some softwares involved. All
softwares are located in the Award HDD Service Routine (1NT 13h). It may fail to access
a HDD with LBA (LARGE) mode selected if you are running under on Operating System
which replaces the whole 1NT 13h. UNIX operating systems do not support either LBA
or LARGE and must utilize the Standard mode. UNIX can support drives larger than
528MB.

Appendix C : AGP Driver for Windows 95 Installation Guide
This section provides the information for installation of Apollo VP3 VxD Driver
which supports Accelerated Graphics Port (AGP) functionalities.
SYSTEM REQUIREMENTS
1.Microsoft Windows 95 OSR2.1 (OSR2.0 with USB upgrade)
2.VIA Apollo VP3 AGP Driver (Vgart.VXD)
3.AGP VGA Card with Driver
4.Direct X5 DDk or SDK
INSTALLATION PROCEDURE
Step 1. Install Windows 95 4.00.950 B or later version
Step 2. Install USBSUPP (USB upgrade)
Step 3. Install Apollo VP3 AGP Driver
-run the program "SETUP.EXE" which can be found in the VIA VxD driver
disk and this process will then automatically install the VIA VxD driver onto
your windows 95 system.
Step 4. Install VGA driver for Windows 95
Step 5. Install Microsoft Direct X5 DDK or SDK
NOTES
1. This driver should be installed on a system with the VIA Apollo VP3 AGP chipset
while other chipsets is not be supported. The VIA VxD Driver is only
supported by Windows 95 OSR 2.0 (4.00.950 B) ro later versions.
2. For Win95 users, you will need to
a. Get "USBSUPP.EXE" from Microsoft (www.microsoft.com), which includes
the USB supplement and a new memory manager (VMM32.VxD) needed for
the AGP DIME (Direct Memory Execute) feature.
b. Get DirectX 5.0 from Microsoft (www.microsoft.com). DirectX 5.0 is the first
DirectX version that supports AGP's DIME.
c. Get "VIAGART.VXD", a virtual device manager which is usually installed
during the installation procedure of the Windows 95 card driver.
3. To make sure if the Apollo VP3 AGP driver is properly installed, one must boot
the Windows 95 system up and run "Regedit" and check whether the file
VIAGART exists in the following path
"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD
4. To check whether the AGP driver is able to activate, one must do the following:
a. Activate the "Control Panel"
4-12
CHAPTER 4
b. Click on "Direct X" then
c. Click on "Direct Draw" and
d. Check if there are some values existing in the "Bit" and "overlays."
if there is, that means the AGP can be activated properly.
REPLACING AN EXISTING VGA CARD WITH THE AGP VGA
CARD
1. Shut down the computer and then turn off the power
2. Replace the VGA card boot up the system once again
3. Now, Update Device Driver Wizard Window will appear. This wizard will
complete the installation of the Standard PCI Graphics Adapter (VGA).
Click Next > to let Windows search for an updated driver.
WARING ! Only click Next >. The system will hang if you click Cancel!
4. Click Finish to install the VGA driver. You will then be asked for your Windows
95 CD in order to complete the VGA driver installation. If you do not have your
CD handy, direct the installation path to your \windows\system directory.
Windows will prompt you to restart your windows. Chose "NO" and install the
appropriate AGP VGA Driver
