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 pseudosynchronous 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

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.

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.

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 3-1

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.

Again, users can move the cursor by pressing direction keys to the field needed to be modified and press <PgDn> or <PgUp> to alter item selection. You can only change the content of Doze Mode, Standby Mode, and Suspend Mode when the Power

Management is set to 'User Define'.

3-3-1 The Description of the Power Management

A. Power Management mode selection :

Disabled : The system operates in NORMAL conditions (Non-GREEN)

and the Power Management function is disabled.

Max. saving: This mode will maximize the power saving capability.

Min. saving: This mode will minimize the power saving capability.

User define: Allow user to define time-out parameters to control power saving 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 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.

1-31 : Represets the date of the month that you need the system to turn on.

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.

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.

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 do not need the "IDE HDD AUTO

DETECTION" utility. The BIOS will Auto-detect the hard disk size and model on display during POST.

Figure 3-9 IDE HDD AUTO DETECTION

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.

no. Cyclinder (1024)

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!

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:


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:


x no. Head ( 32)

x no. Sector ( 63)

x bytes per sector ( 512)

1 Gigabytes

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.

3-10 HDD LOW LEVEL FORMAT

Interleave

Select the interleave number of the hard disk drive that 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.

This allows the utility to scan first then format by each track.

Start

Press<Y>to start low level format.

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

3-12 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.

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"


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
