3.2 Placement
The P6NS PPro SCSI Motherboard 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 performanceIDEinterfacesfor up to four
IDE devices (harddevices, CD-ROM device, etc). The Adaptec(AHA-2940UW)
Ultra/ Ultra Wide SCSI built in this SCSI motherboardprovidesnot only the
powerful connectivity but also softwaredriver supported by original Adaptec.
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 capableparallel
port. The P6NS layout is shown in next pagefor user's reference. Care must be
taken when inserting memorymodules, inserting Pentium Pro processor CPU or
even plugging PCI card into associated slots to avoid damagingany circuits or
sockets on board.A right fan and heatsink fan isrequired when installing Pentium
Pro processor due to possible overheat.
The P6NS supportsminimum of 8MB of System Memory and maximum of
512MB while L2 Cacheand cache controller included in Pentium Pro Processor .
The P6NS supportsstandard Fast Page, EDO (Extended Data Out or Hyper Page
Mode) or Burst EDO DRAM. The P6NS provides four 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 memorymodules. 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

9
parity (x 72)or non-parity(x 64)or ECC(x 72). The BIOS will automatically detect
which DRAM hasinstalled in SIMM sites.
The P6NS supportsOnboard two PCI IDE connectors,and detectsIDE
harddisk type by BIOS utility automatically.
The P6NS 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.

NOTE :
1. P6NS supports very flexiblememory configurationswith its 4 SIMM
sockets. The memory size of any configuration can be combined flexibly.
BIOS will detect your memory configurations and sizes automatically.
2. P6NS support Fast Page DRAM, EDO or BEDO DRAM SIMMs, but
cannot be mixed within the same memory bank.
3. SIMMs may be parity (x 72) or non parity (x 64) or ECC(x 72).
4. The 60nS EDO/BEDO DRAM is necessary.
5. The "BANK" means 64 Bit, means either M1+M2 or M3+M4
3.5 Integrated PCI Bridge
The P6NS utilizes Intel's 440FX PCI set chipset to support Pentium Pro

15
Processor PCI/ISA system. The Intel 82440FX PCI set chipset consists of the
82441FX PCI and Memory Controller (PMC), 82442FXData Bus Accelerator
(DBX) devices, and one82371SBPCI 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 performancePCI arbitor
to supportfour PCI Masters, RotatingPriority Mechanism,Hidden Arbitration
Scheme Minimizes Arbitration Overhead,and PCI Rev.2.1 compliant.The PMC
provides bus control signals and addresspathsfortransfersbetween 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 interfacesto the 16-bit Private data busfor PCI
transactionsand providing optimalCPU-to-DRAM performance.
There are four interrupts in each PCI slot : INTA#, INTB#, INTC#, and INTD#.
Since the P6NS adaptsthe PCI auto-configuration with the system BIOS Setup
utility. When the system is turned on afteraddinga PCI add-in card, the BIOS
automatically configureinterrupts, DMA channels,I/O space,and other
parameters.You do not have to configure jumpers or worry potentialresource
conflicts. BecausePCI cards use the sameinterrupt resource as ISA cards,you
mustspecify the interrupt used by ISA add-in cardsin the BIOS Setup utility.
If however, a "Legacy card" (such as plug paddlecardandcableinto the ISA
slot.) is plugged in the system, modification in the <ROM SETUP UTILITY>
becomesnecessary. 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 plug 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 manualof 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 takesINTB
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).
