Introduction

The PP6-NF motherboard is a high performance system hardware

based on Intel Pentium Pro processor and is equipped with four PCI slots, four standard ISA slots, Super Multi-I/O controller and dual ports PCIIDE connectors for the future expansion. The hardware dimension is Full ATX form factor with four layer design technology.

1-1 Pentium Pro Processer Overview

The Intel Pentium Pro Processor is the 6th generation in the Intel 386

Intel 486TM, and Pentium family of processors. The Pentium Pro

Processor has several key features such as 12-stage superpipeline architecture, Built-in 256KB/512KB cache, Out of order execution, dynamic branch prediction & speculative execution and a pipestage time 33 percent less than the Pentium Processor, which helps achieve a higer clock rate on any given Process. It will be superpipelined for high clock speed from 150MHz up to 233MHz. The Pentium Pro Processor was used to the

Dynamic Execution that is the combination of improved branch prediction, speculative execution and data flow analysis that enables the Pentium Pro processor to deliver its superior performance from CPU architecture.

The Pentium Pro Processor is a 64 bit processor with RISC technology. It requires 32-bit applications (like Microsoft Windows NT and OS/2) to optimize its capabilities and performances. The Pentium Pro processor

delivers best value for businesses moving to 32-bit computing when useing the 32-bit Operating System and Applications.

Hardware design

2-1 Motherboard Layout The PP6-NF is designed with Intel 82440FX PCIset chipset which is developed

by INTEL Corporation to fully support Pentium Pro Processor PCI/ISA system. The Intel 82440FX PCIset chipset provides increased integration and improved performance designs. The chipset provides an integrated IDE controller with two high performance IDE interfaces for up to four IDE devices (hard devices, CDROM device, etc). The SMC 37C669 Super I/O controller provides the standard PC I/O function: floppy interface, two 16 Byte FIFO serial ports and EPP/ECP capable parallel port. The PP6-NF layout is shown in nexts page ( Figure 1-1 ) for user's reference. Care must be taken when inserting memory modules, inserting Pentium Pro processor CPU or even plugging PCI card into associated slots to avoid damaging any circuits or sockets on board. A right fan and heatsink fan is strongly recommended when installing Pentium Pro processor due to possible overheat.

The PP6-NF supports minimum of 8MB of System Memory and maximum of

768MB while L2 Cache and cache controller included in Pentium Pro Processor CPU.

The PP6-NF supports standard Fast Page, EDO (Extended Data Out or Hyper

Page Mode) or Burst EDO DRAM. The PP6-NF provides six 72-pins SIMM sites for memory expansion. The socket support 1M x 32(4MB), 2M x 32(8MB), 4M x 32(16MB), 8M x 32(32MB) 16MB x 32(64MB), and 32MB x 32(128MB) single-sided or double-sided memory modules. The memory timing requires 70 nS Fast page devices or 60 nS EDO DRAM. Memory parity generation and checking or ECC(Error Checking and Correction) are supported(DRAM Modules may be parity (x 72)or non-parity(x 64)or ECC(x 72). The BIOS will automaticlly detect which DRAM has installed in SIMM sites.

The PP6-NF supports Onboard two PCI IDE connectors, and detects IDE

harddisk type by BIOS utility automatically.

The PP6-NF supports Award Plug & Play BIOS for the ISA and PCI cards. The

BIOS can be located in Flash EPROM. The advantage of having Flash EPROM is much easier to replace BIOS code if necessary.

The PP6-NF's motherboard layout and system block diagram are shown in

2-4 Integrated PCI Bridge

Hardware Design 2-9

The PP6-NF utilizes Intel's 440FX PCIset chipset to support Pentium Pro

Processor PCI/ISA system. The Intel 82440FX PCIset chipset consists of the 82441FX PCI and Memory Controller (PMC), 82442FX Data Bus Accelerator (DBX) devices, and one 82371SB PCI ISA/IDE Accelerator (PIIX3) 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, Hidden Arbitration Scheme Minimizes Arbitration Overhead, and PCI Rev.2.1 compliant. The PMC provides bus control signals and address paths for transfers between the host bus, PCI bus, and main memory. The DBX is used to create the 64-bit CPU to main memory data path and DBX also interfaces to the 16-bit Private data bus for PCI transactions and providing optimal CPU-to-DRAM performance.(reference Figure 1-2 simple architecture)

There are four interrupts in each PCI slot : INTA#, INTB#, INTC#, and INTD#. Since the PP6-NF 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 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.

If however, a "Legacy card" (such as plug paddle card and cable into the ISA slot.) is plugged in the system, modification in the ROM SETUP UTILITY becomes necessary. First, enter PCI CONFIGURATION SETUP utility from ROM SETUP UTILITY main menu to set the " PCI IDE IRQ MAP TO : ISA". Secondly, you must enter CHIPSET FEATURES SETUP UTILITY from ROM SETUP UTILITY main menu and set the "Onboard Primary PCI IDE: Disabled and Onboard Secondary PCI IDE: Disabled." When you plugg the PCI/ISA IDE card into the system, You should Disabled Onboard Primary and Secondary PCI IDE from CHIPSET FEATURES SETUP UTILITY too.

Some "Legacy card" ( no paddle card and cable.) you can set the system interrupt request (IRQ) on the "Legacy card" (refer to user's manual of the card) to a proper system IRQ level (in general, card's Primary assigned to INTA and Secondary assigned to INTB). If the card is plugged into slot 1(marked PCI#1), you can not 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 enter PCI CONFIGURATION SETUP utility from ROM SETUP UTILITY main menu and set the "PCI IDE IRQ MAP TO : PCI-Slot 1" (depend on the slot # where the Legacy card is plugged). .

ATX FORM-FACTOR

OVERVIEW

The PP6-NF has been designed with ATX form-factor. The board size is 12" x 9.6"

(305mm x 244mm). The ATX from-factor improves over Baby AT and LPX in a number of ways. By using the ATX chasis then the power supply orientation and specification and rotating the Baby AT baseboard through 90 degrees, the pentium Pro processor can be relocated away from the expansion slots, and the longer side of Add-on card can be used to host more on board I/O. From Figure 3-1: Summary of ATX chassis features layout the user can gain a great deal improved functionality.

The PP6-NF Supports two power input connectors. Two 6-PIN connetors (for AT

power supply) and a single 20-PIN connectors (for ATX power supply). (see Figure 1-1) For ATX power supplies that support the Remote ON/OFF feature, the should be connectoed to the system front panel for system power ON/OFF switch. The system power ON/OFF button should be a momentary Switch that is normally open. If you use traditional power Supplies (AT Power Supply) with mechanical ON/OFF switches or buttons, this Remote ON/OFF function is not available.

The PP6-NF has been designed with "soft off" functions. You can turn OFF the system from one of two sources: One is the front panel power ON/OFF switch, and the other is "Soft off" function (coming from the PP6-NF on-board's circuit controller) that can be controlled by operating system. Such as Windows 95: When the

user clicks on the Shutdown icon, power can be turned off directly.(If Disabled the power Management in the BIOS POWER MANAGMENT SETUP. The "soft off" function will be disabled.)

AWARD BIOS SETUP

Award's ROM BIOS provides a built-in Setup program which allows user 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 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.

Page 27

AWARD BIOS 4-9

B.Timeout 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 timeout setting is from 1 minute up to 1 hour.

System Standby

The "Standby" mode timer starts to count when "System Doze" mode timer timed out and no "PM events" occurred. Valid range is from 1 minute up to 1 hour.

System Suspend

This function works only when the Pentium Pro 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.

4-4-2 Description of the Green Functions

The PP6-NF supports HDD Power Down, Doze and standby power saving functions when Intel Pentium Processor is installed. In addition, the suspend function is supported when the J5 (sleep ref. Figure1-1) be close to enter the green function. The detail description of these functions are provided in next page.

HDD Standby Mode

When system stop 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 timeout occurrs.

Standby Mode

When the system standby mode timer runs out, it will enter the standby mode and retain CPU at slow working speed. The screen will be blanked out.

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 consunption in Suspend Mode is lower than in standby mode. The screen is also blanked out.

Page 28

4-10 CHAPTER 4

PM Events:

AWARD BIOS defines 15 PM Events in the power management mode (Doze, standby & 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" isn't "Disabled". Once the system Doze timer is timed out, it will process doze power saving procedure by starting the system standby timer. When the standby timer ran out and all of the "Enabled" events remains silent, the system will enter the standby mode. By now, the system will not only process the standby power saving procedures but also start the system suspend timer. When the suspend timer times out , all of the CPU clock will be stopped 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 & LARGE NORMAL mode Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing. The maximum nunber of cylinders, head & sectors for NORMAL mode are. 1024, 16 & 63. no. Cyclinder (1024) x no. Head ( 16) x no. Sector ( 63) x no. per sector ( 512) 528 Megabytes If user set his HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that!

Page 35

AWARD BIOS 4-17

LBA (Logical Block Addressing) mode

A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD.

During HDD accessing, the IDE controller will transform the logical address described by sector, head & 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

Extended HDD access mode supported by Award Software.

Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, user do 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 nultiplied by 2. Areverse transformation process will be made inside INT 12h in order to access the right HDD address the right HDD address!

Maximum HDD size:

no. Cyclinder (1024) x no. Head ( 32) x no. Sector ( 63) x bytes per sector ( 512) 1 Gigabytes

Page 36

4-18 CHAPTER 4

Note: To support LBA or LARGE mode of HDDs, there must be some

softwares involved. All these softwares are located in the Award HDD Service Routine (1NT 13h). It may be failed to access a HDD with LBA (LARGE) mode selected if you are running under a 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.
