About this manual
This P55TU SCSI Motherboard is the newest memberto our SCSI Motherboard
solution products families. It incorporated with Intel4th generation 430HX
Chipset with BGA technology and with Adaptecnew Ultra / Ultra Wide SCSI
embedded which is equilevent to AHA 2940UW. AdaptecRAID port option
ready is a big advantage in this P55TU SCSI motherboard.It can turn this SCSI
motherboard to support hardware SCSI RAID by addingthe RAIDBUS 1000 or
the ARO 1130 adapterfrom Adaptec.
Run with fasterCPU is very important function that thisSCSI Motherboard support.
It support bothP54C up to 200 MHz* and Intel’s next generation P55C processor
with MMX technology.
Feature with Error Check Correction ( ECC ) system memory is another plus on
this SCSI Motherboard to outperform the whole system stability. It equipe 4 of the
72 pin SIMM that supportsEDO DRAM with ECC.

Warning
This motherboard is carefully designed with Intelspec. to fully supportP54C
processor up to 200Mhzand thenew P55C. Since Intel is notshiping theP54C
with 200Mhz and the new P55C CPU at the point that we deliver this
motherboard so we hold theresponsibility on if Intelchange any spec. that cause
the new processor not function properly in this motherboard.

3.3.1 CPU Socket
This CPU socket provides flexibility for Intel Pentium , Pentium
OverDrive, Pentium future processors, AMD (5k86) and Cyrix (6x86)
processor. When installing the CPU into the Zero Insertion Force ( ZIF )
socket should be very carefully. Lift thehandleof this 321 Pin ZIF socket
up carefully and insert the CPU into ZIF socket. And makesure the CPU
Pin 1 is with the square base andit goes to particular hole onthe ZIF
socket. Once you match the hole with Pin 1 then gently insert the CPU and
press socket handle down.

3.3.2 J22 CPU Cooler Fan PowerConnector
Warning !!! Warning !!! Warning !!!
CPU Cooler is required to be placed on top of the CPU
all the times to prevent CPU over-heat.

3.3.3 CPU Clock Select
To set the correct CPU clock select forthe Intel Penitum basedCPU to
this motherboard.You need to set both the CPU External Clock Frequency
and the CPU to bus frequency ratio correctly. But this motherboard special
design with a one jumpermoveto set the CPU clock select and you only
need to place thejumpercap into the CPU clock that you desire. The JP10
is a 2 X 9 pin jumper,with one "colored" jumpercap on it. One and only
one jumpercap ( Expect when you use the Cyrix 120+ CPU ) need to put
on this connectorfor selecting theCPU clock. Simply place thecolored
yellow jumpercap to the speed of theCPU really is (the CPU
internal/externalclock ratio andISA clock will be automatically selected
by setup the JP10)

Bank 0 Bank 1
The P55TU supports different type of system memory. No jumperneeded for this
function or configure. This mainboard separates four pieces of 72 pins
SIMM(Single In Line Memory Module) into two banks.
NOTE:

. P55TU supportsEDO DRAM.
2 . The 60 ns EDO DRAM is required.
3.6 SCSI Interface
3.6.1 J3 Ultra Wide SCSI Connector
J3 is a 68 pins 16 bit internal Ultra Wide SCSI connector.Itattachesthe
SCSI cable(s) from the P55TU SCSI controller to the SCSI peripherals.
The externalSCSI port expansion kit is a optionalfor your connecting
externaldevices. Be-sure the cable's colored side should align to pin #1 of
this connector.

SCSI cablemust run sequentially from one device to the next,with no
branches.

Note: The 50 pin SCSI is an 8 bit SCSI bus, the 68 pin SCSI is a 16 bit SCSI bus
which hasa pin-to- pin connected to the 50 pins SCSI connector.
Note: The SCSI termination must be onforthe both side. The beginer and end
must set the terminator on - otherwise the SCSI bus will not operate properly.
Forlinking both the 50 & 68 pin SCSI together, the High byte terminator must
set to on and Lowbyte set to off.

3.6.3 Set SCSI IDs
You must assign a different SCSI ID to each device on the SCSI bus
connected to the P55TU system board. See yourSCSI device
documentation fordirections on how to determine theID and change it.
◼Ultra/ Ultra Wide SCSI devices that connect to this mainboard'sSCSI
connectorcan be assigned ID from 0 to 15(for 68 pin Wide SCSI
connection). Normally, the host will use ID7. Or reference to Chapter5 for
more information.
◼The SCSI ID0 is the best use for SCSI harddisk to be used asyour
computer'sbootdevice, ID1 is best reserved for a secondarySCSI hard
disk.(This is only when you use the SCSI hard disks and devices.)
