1. Introduction
1.4 Notes On Installation
his motherboard has been designed with the Intel 82430 X, PCI
chipset, which was developed by Intel Corporation to fully support
the Pentium Processor PCI/ISA system. he Intel 82430 X PCI
chipset provides increased integration and improved performance.
he chipset provides an integrated IDE controller with two high
performance IDE interfaces, for up to four IDE devices (hard devices,
CD-ROM device, etc). he I E 8679/8687 Super I/O controller
provides standard I/O functions: floppy interface, two serial ports with
16-Byte FIFO buffers, and an EPP/ECP-capable parallel port.
Care must be taken when inserting memory modules, inserting the
CPU, or even plugging PCI cards into associated slots to avoid
damaging any circuits or sockets on the motherboard. A cooling fan
is strongly recommended when installing P54C, P54C B, P55C, K5,
K6, 6x86, or M2 CPU, to avoid overheating.
he motherboard requires a minimum of 4MB of system memory,
and can support a maximum of 256MB.
he onboard L2 Cache comprises 256KB or 512KB of synchronous
SRAM to increase system performance.
he motherboard supports standard Fast Page (FP), EDO (Extended
Data Out), or SDRAM (Synchronous DRAM) memory, and provides
four 72-pin SIMMs and two 168-pin DIMMs. he sockets support
1Mx32(32MB) single-sided or double-sided memory modules.
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 non-parity (x32).
he board also has two onboard PCI IDE connectors, and detects the
IDE hard disk type through an automatic BIOS utility. he system
also supports Award Plug & Play BIOS for the ISA and PCI cards.

2.3 System Memory (SIMM and DIMM)
his motherboard supports four 72-pin SIMMs (Single Inline
Memory Modules) of 4MB, 8MB, 16MB, 32MB, and/or 64MB to
form a memory size between 8MB to 256MB. he DRAM can be
either 60ns or 70ns Fast Page Mode (FPM, Asymmetric or
Symmetric), Extended Data Output (EDO). SIMMs must be installed
in pairs so that each bank contains two of the same size memory
modules.
Install memory in any or all of the banks an any combination as
shown in the table below:
Item Bank Memory Module
1 DIMM 1 8-128MB
2 DIMM 1, 2 8-128MB
3 DIMM 2

NOTE: You cannot mix two types (FPM, EDO, or SDRAM) or sizes
of memory in a single bank. After installing any memory modules,
setup is required using "Auto Configuration" in the Chipset Features
section of BIOS setup.

2. Installation
2.3.1 IMM/DIMM Memory Installation Procedures:
1. he SIMM memory modules will only fit in one orientation
because of a plastic Safety Tab on one end of the SIMM socket
which exactly fits the notched end of the SIMM module.
2. Press the SIMM into its socket at a 45-degree angle to the
motherboard, making sure that all the contacts are aligned with the
socket.
3. With you finger tips, gently push the memory module into a
vertical position so that it clicks into place.
4. he plastic guides should go through the two mounting holes on
the sides and the metal clips should snap on the other side.
5. o remove a memory module, squeeze both metal clips outwards
and rock the module back to a 45-degree angle, then lift it out of
the socket.
6. his motherboard is optimized for SDRAM performance: It
supports the new generation Synchronous Dynamic Random
Access Memory (SDRAM), and allows combined usage of SIMM
and DIMM memory modules.
2.4 Central Processing Unit (CPU)
he motherboard provides a 321-pin ZIF Socket 7. he CPU should
have a fan attached to it to prevent overheating. If the CPU did not
come with a fan 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 can overheat and cause damage to
both the CPU and the motherboard.
2.4.1 Installing the CPU
o 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-
EP-P 11 User's Manual

2. Installation
degree angle. Insert the CPU with the correct orientation. he ZIF
socket has a square pattern of pinholes, but there is one hole missing
from the pattern in one corner. On the CPU, there is a white dot
printed near one corner, on the top face. Be sure that the white dot on
the CPU lines up with the odd corner of the socket. If you try to
insert the CPU in the wrong orientation, you could damage it!
You should have a CPU fan that will cover the face 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 xternal Clock (BUS) Frequency
Selection and CPU to BUS Frequency Ratio according to the type of
CPU you install.
( ee chapter 3 CPU Settings for more information.)
2.4.2 Expansion Cards
Both ISA and PCI expansion cards may need an assigned IRQ.
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. he original ISA expansion card
design, now referred to as Legacy ISA, 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 to
see a map of your used and free IRQs. For Windows 95 users, open
the "Control Panel" icon in "My Computer", and double-click on the
"System" icon, then click on the "Device Manager" tab. Double
clicking on a specific device gives 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.
o 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
EP-P 11 User's Manual
10

2. Installation
system. For PnP cards, IRQs are assigned automatically from those
currently 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. he PCI
and PnP Configuration section of the BIOS setup utility can be used
to indicate which IRQs are being used by Legacy cards. For older
Legacy cards that do 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 any PCI slot which has a card that
requires an IRQ. o install a PCI card, you need to set something
called the IN (interrupt) assignment. Since all the PCI slots on this
motherboard use an IN A#, be sure that the jumpers on your PCI
cards are set to IN A.
2.4.2.1 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" under PnP and PCI Setup in the
BIOS Setup, otherwise conflicts may occur.
