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 384MB 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 three 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 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
pseudo-synchronous operation of the processor and DRAM, AGP and PCI buses.
The JP5 allows user to set the SDRAM Frequency between 66/100MHz.

JP5 SDRAM Clock Selection
1-2 : Fixed as 66MHz

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.

>
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.

2-5 External Modem Ring-in Power ON and Keyboard Power
ON Functions
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, this mainboard 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 ourselves to create the
easiest and most convenient way to turn on your system based on the the ATX
power supply. This function is available only under system being connected to
ATX power supply.
How to work with it
Step 1: Please place JP4 at the position 2-3 after you finished the system
installation.
Step 2 : Push the momentary switch to turn on your system and then push again to
hold for more than 4 seconds to turn it off as soon as you turn it on.
Step 3: You can enjoy the Keyboard Power ON function by pressing any 1 or 2
keys on you keyboard at the same time for 1-2 seconds. 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:
1. The number of keys needed to turn on a system depends on the model of
keyboard you are appplying due to different loadings on different keyboards.
Here, we would like to suggest you push 2 keys at the same time..
2.Intel ATX version 2.0 specification has recommended you use the power
supply with 0.72A(720mA). With our EP-58MVP3C-M
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 by placed JP4 at the position 1-2 to disable this
feature.

2-6 Integrated PCI Bridge
This mainboard utilizes VIA Apollo MVP3 AGP/PCIset chipset to support Intel
Pentium Processor PCI/ISA system. The VIA Apollo MVP3 PCIset chipset
consists of the 82C598AT system controller (TSC), and one 82C586B PCI ISA/
IDE Accelerator bridge chip. It provides an interface which translates CPU cycle
into PCI bus cycle, and PCI burst read/write capability. In addition, it provides high
performance PCI arbitor to support four PCI Masters, Rotating Priority
Mechanism, and Hidden Arbitration Scheme Minimizes Arbitration Overhead.
There are four interrupts in each PCI slot : INTA#, INTB#, INTC#, and INTD#.
Since this mainboard adapts the PCI auto-configuration with the system BIOS
Setup utility. When the system is turned on after adding a PCI add-in card, the
BIOS automatically configure interrupts, DMA channels, I/O space, and other
paramaters. You do not have to configure jumpers or worry about potential resource
conflicts. Because PCI cards use the same interrupt resource as ISA cards, you must
specify the interrupt used by ISA add-in cards in the BIOS Setup utility.
However, if a "Legacy card" (such as plugging a paddle card and cable into an ISA
slot) is plugged in the system, modification in the ROM SETUP UTILITY
becomes necessary. First of all, you must enter PCI CONFIGURATION SETUP
utility from the ROM SETUP UTILITY main menu to set "ISA" for the "PCI
IDE IRQ MAP TO
Secondly, you must enter the CHIPSET FEATURES SETUP UTILITY from the
ROM SETUP UTILITY main menu and set "Disabled" for the "Onboard
Primary PCI IDE and the Onboard Secondary PCI IDE. When you plug PCI/
ISA IDE cards into the system, You should select "Disabled" for the Onboard
Primary and Secondary PCI IDE from the CHIPSET FEATURES SETUP
UTILITY too.
You can set the system interrupt request (IRQ) on some "Legacy cards" which have
on paddle card and cable. (refer to user's manual of the card) to a proper system
IRQ level (In general, card's Primary is assigned to INTA and Secondary is
assigned to INTB). If the card is plugged into slot 1(marked PCI#1), you cannot
use second slot (marked PCI#2) because the Secondary INT signal takes INTB from
the slot (refer to Page 3-12 for circuit diagram). The user then enters the PCI
CONFIGURATION SETUP utility from the ROM SETUP UTILITY main
menu and set "PCI-Slot 1" for the "PCI IDE IRQ MAP TO (This depends on the
slot # where the Legacy card is plugged).

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.

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.
Page 24
AWARD BIOS 3-11
RTC Alarm Resume
This option allows you to have the system turn on at a preset time each day or on a
certain day. This option is only available when used an ATX power supply.
Enabled : The system will turn on at the preset time.
Disabled : Normal Setting
Date(of month)
This field is to set the date that the system will turn on. The default value is 0.
0 : Turn on the system on everyday at the preset time.

Time (hh:mm:ss)
This field is to set the time that you need the system to turn on. The default value
is 08:00:00.
HDD Standby Mode
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.
Page 25
3-12 CHAPTER 3
PM Events:
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.

NOTE: HDD Modes
The Award BIOS supports 3 HDD modes : NORMAL, LBA and LARGE
NORMAL mode.
Generic access mode that is neither the BIOS nor the IDE controller will
make transformations during accessing.
The maximum nunbers of cylinders, head & sectors for NORMAL mode are
1024, 16 and 63.

x no. Head ( 16)
x no. Sector ( 63)
x no. per sector ( 512)
528 Megabytes
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!
Page 32
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:
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. Cyclinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)

Page 33
3-20 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"
Page 44
TECHNICAL INFORMATION 4-11
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
