2-1 Motherboard Layout
The motherboard is designed with Intel 82430VX, PCI
chipset which is developed by Intel Corporation to fully
support Pentium Processor PCI/ISA system. The chipset
provides an integrated IDE controller with two high
performance IDE interfaces for up to four IDE devices
(hard disk driver, LS-120 floppy driver, CD-ROM device,
etc). The ITE 8680/8687 Giga I/O controller provides the
standard PC I/O function: floppy interface, two 16Byte
FIFO serial ports and EPP/ECP capable parallel port. Care
must be taken when inserting memory modules, inserting
CPU 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
P54C/P54CTB/P55C/K5/6x86 due to possible overheat.
The motherboard supports minimum of 8MB of system
memory and a maximum of 128MB.
L2 Cache can be 256KB/512KB Pipelined Burst SRAM
onboard to increase system performance.
The motherboard supports standard Fast Page(FP),
EDO(Extended Data Out). The motherboard provides four
72-pins SIMM. The socket supports 4MB, 8MB, 16MB,
32MB, mixed each bank of memory upto 128MB. The
memory timing requires 70ns Fast Page devices or 60ns
EDO RAM. Memory parity generation and checking is not
supported. (DRAM Modules may be parity (x36) or nonparity (x32).
The board also supports Onboard two PCI IDE connectors,
and detects IDE hard disk type by BIOS utility automatic.
The system also supports Award Plug & Play BIOS for the
ISA and PCI cards.

2. INSTALLATION
2-5 Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7. The
CPU that came with the motherboard should have a fan
attached to it to prevent overheating. If this is not the case
then purchase a fan before you turn on your system. Apply
thermal jelly to the CPU top and then install the fan onto
the CPU.
NOTE: Without a fan, the CPU may overheat and cause
damage to both the CPU and the motherboard
To install a CPU, locate the ZIF socket and open it by first
pulling the lever sideways away from the socket’s “Lock”
then upwards to a 90-degree right angle to insert the CPU
with the correct orientation. You should have a CPU fan that
will cover the surface of the CPU. With the added weight of
the CPU fan, no force is required to insert the CPU. Once
completely inserted, hold down the fan and close the socket’s
lever.
NOTE: You must set the CPU External Clock Frequency
Selection” and “CPU Internal Frequency Ratio”
depending on the CPU that you install.

2-6 Expansion Cards
Expansion Card Installation Procedures:
1. Read the documentation for your expansion card.
2. Set any necessary jumpers on your expansion card.
3. Remove your computer system’s cover.
4. Remove the bracket on the slot you intend to use. Keep
the bracket for possible future use.
5. Carefully align the card’s connectors and press firmly.
6. Secure the card on the slot with the screw you removed
in step 4.
7. Replace the computer’s system cover.
8. Setup the BIOS if necessary
9. Install the necessary software drivers for your expansion
card.
Assigning IRQs for Expansion Cards
Some expansion cards need to use IRQ to operate. Generally
an IRQ must be exclusively assigned to one use. In a
standard design there are 16 IRQs available but most of them
are already in use by parts of the system which leaves 6 free
for expansion cards.
12 EP-PV12 User’s Manual
Page 18
2. INSTALLATION
2-6 Expansion Cards (continue…)
Both ISA and PCI expansion cards may need to IRQs. System
IRQs are available to cards installed in the ISA expansion bus
first, and any remaining IRQs are then used by PCI cards.
Currently, there are two types of ISA cards. The original ISA
expansion card design, now referred to as “Legacy” ISA cards,
requires that you configure the card’s jumpers manually and then
install it in any available slot on the ISA bus. You may use
Microsoft’s Diagnostic (MSD.EXE) utility included in Windows
directory to see a map of your used and free IRQs. For Windows
95 users, the “Control Panel” icon in “My Computer”, contains a
“System” icon which gives you a “Device Manager” tab. Double
clicking on a specific device give you “Resource” tab which
shows the Interrupt number and address. Make sure that no two
devices use the same IRQs or your computer will experience
problems when those two devices are in use at the same time.
To simplify this process this motherboard has complied with the
Plug and Play (PnP specification which was developed to allow
automatic system configuration whenever a PnP-compliant card
is added to the system. For PnP cards, IRQs are assigned
automatically from those available.
If the system has both Legacy and PnP ISA card installed, IRQs
are assigned to PnP cards from those not used by Legacy cards.
The PCI and PnP configuration of the BIOS setup utility can be
used to indicate which IRQs are being used by Legacy cards.
For older Legacy cards that does not work with the BIOS, you
can contact your vendor for an ISA Configuration Utility.
An IRQ number is automatically assigned to PCI expansion
cards after those used by Legacy and PnP ISA cards. In the PCI
bus design, the BIOS automatically assigns an IRQ to a PCI slot
that has a card in it that requires an IRQ. To install a PCI card,
you need to set something called the INT (interrupt) assignment.
Since all the PCI slots on this motherboard use an INTA#, be
sure that the jumpers on your PCI cards are set to INTA.

2-6 Expansion Cards (continue…)
Assigning DMA Channels for ISA Cards
Some ISA cards, both Legacy and PnP may also need to use a
DMA (Direct Memory Access) channel. DMA assignments for
this motherboard are handled the same way as the IRQ
assignment process described above. You can select a DMA
channel in the PCI and PnP configuration section of the BIOS
Setup utility.
NOTE: Choose “Yes” for those IRQ’s and DMA’s you wish
to reserve for Legacy (Non-PnP) ISA expansion cards in
“IRQ xx Used by ISA” and “DMA x Used By ISA” of the
PnP and PCI Setup in the BIOS Software section, otherwise
conflicts may occur.

3. BIOS SOFTWARE
3-1 Introduction
AWARD BIOS ROM provides a built-in setup program that
allows users to modify the basic system configuration and
hardware parameters. The modified data will be stored in a
battery-backed CMOS RAM so data will be retained even when
EP-PV12 User’s Manual 23
Page 29
the power is turned off. In general, the information saved in the
CMOS RAM stay unchanged unless there is configuration
change in the system, such as hard drive replacement or new
equipment change.
It is possible that CMOS had a battery failure which cause data
lose in CMOS RAM. If so, re-enter system configuration
parameters become necessary.
The Award BIOS is immediately activated when you first power
on the computer. The BIOS reads the system information
contained in the CMOS and begins the process of checking out
the system and configuring it. When it finishes, the BIOS will
seek an operating system on one of the disks and then launch and
turn control to the operating system.
While the BIOS is in control, the Setup program can be activated
in one of the two ways:
1. By pressing <Del> immediately after switching system on, or
2. by pressing the <Del> key when the following message
appears briefly at the bottom of the screen during the POST
(Power On Self Test). Press <Del> to enter SETUP.
If the message disappears before you respond and you still wish
to enter Setup, restart the system to try again by turning it OFF
then ON or pressing the “RESET” button on the system case.
You may also restart by simultaneously pressing <Ctrl>, <Alt>,
and <Del> keys. If you do not press the keys at the correct time
and the system does not boot, an error message will be displayed
and you will again asked to …

Hard Disk Mode: Install hard disk (such as MFM, ESDI or
IDE) to your system, you need to have their specifications
recorded here. The SCSI drives operate using device drivers
and are not supported directly by BIOS.
For IDE hard drives, the BIOS provides three modes to support
both normal IDE hard disks and also drives larger than 528MB.
3. BIOS SOFTWARE
3-3 Standard CMOS SETUP (Continue..)
Normal Mode - for IDE drives smaller than 528MB.
LBA Mode - provide LBA (Large Block Addressing) function
for mass capacity hard disk that is larger than 528MB and up to
26 EP-PV12 User’s Manual
Page 32
8.4GB (Giga-Bytes).
Large Mode - doesn’t use LBA function for above mass
capacity hard disk. Large mode is new specifications which
may not be fully supported by all operational systems (MSDOS is OK right now, but is uncommon).
*Write Pre-Compensation - The size of a sector gets
progressively smaller as the track diameter diminishes. Yet
each sector must still hold 512 bytes. Write pre-compensation
circuitry on the hard disk compensates for the physical
difference in sector size by boosting the write current sectors
on inner track.
* Landing Zone - The cylinder location where the heads will
normally park when the system is shut down.
* Capacity = (Number of heads) x (Number of cylinders) x
(Number of sectors per track) x (512 Bytes per sector)

d. Boot Sequence
This option sets the sequence of boot drives (either floppy drive A:
or hard disk drive C that BIOS attempts to boot from after
POST completes.
CD-ROM driver is becoming a standard device on computer
systems. It has a large storage capacity advantage to store different
operating system on it and will need boot-up of the system via CDROM. Now, we provides CD-ROM boot-up function that allows
the user to select booting from drive A, C, or CD-ROM. No matter
if the CD-ROM is IDE or SCSI, the system will look for the first
available bootable device for the operating system.
Swap Floppy Drive: Enabled - The system will swap the floppy
drive assignment so that drive A will function as drive B, drive B
will function as drive A.
Boot Up Floppy Seek: During POST, BIOS will determine if the
floppy disk drive installed is 40 or 80 tracks. (360K type drive is
40 tracks and the 720K, 1.2M and 1.44M are 80 tracks).

g. PCI/VGA Palette Snoop
A system may have two display devices present in the system:
a VGA-compatible interface and another graphics controller.
In this case, both devices implement the color palette registers
at the same I/O addresses. The configuration software must
program on of the devices to actively act as the target, while
the other device is programmed to quietly “snarf” the write
data form the bus as it flies by on its way to the other device.
Some non-standard VGA cards or MPEG video cards may
not show colors properly. You can leave this setting to

LBA (Logical Block Addressing) Mode - A new HDD
Accessing method to overcome the 528 MB bottleneck. The

logical address 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. of Cylinder (1024)
x No. of Head (255)
x No. of Sector (63)
x No. per Sector (512)

AWARD BIOS provides another alternative to support these
kinds of LARGE mode:
CYLS. HEADS SECTOR MODE
