used. BIOS support for this adapter is incorporated on the board in a
Flash memory device. The LSIU160 has a serial EEPROM device for
storing the user’s SCSI bus configuration.
The LSI53C1010 also contains a SCSI SCRIPTS™ processor that
permits both DMA and SCSI commands to be fetched from host memory
or internal SCRIPTS RAM. Algorithms written in SCSI SCRIPTS control
the actions of the SCSI and DMA cores. The SCRIPTS processor
executes complex SCSI bus sequences independently of the host CPU.
For more information on the SCSI SCRIPTS Instruction Set used to write
these algorithms, refer to the LSI53C1010-33 PCI to Dual Channel Ultra3
SCSI Multifunction Controller Technical Manual.

1.3 Interface Descriptions
This section provides a more detailed explanation about the PCI
Interface, the SCSI Interface, Ultra160 SCSI Technology, and LVDlink
Technology.
1.3.1 The PCI Interface
PCI, a high-speed standard local bus, interfaces I/O components to the
processor and memory subsystems in equipment ranging from PCs to
servers. The PCI functionality for the LSIU160 is contained within the
LSI53C1010. The LSI53C1010 connects directly to the PCI bus and
generates signal timing and bus protocol in compliance with the PCI
Specification Revision 2.2.
The PCI interface operates as a 64-bit DMA bus master capable of
64-bit addressing. The connection is made through edge connector J1,
conform to the PCI Local Bus Specification Revision 2.2 standard. The
LSIU160 conforms to the PCI universal signaling environment for a 5 V
or 3.3 V PCI bus.
44.25 pc
1.3.2 The SCSI Interface
The SCSI functionality for the LSIU160 is contained within the
LSI53C1010. This chip is a PCI to Ultra160 SCSI Controller with LVDlink
Universal Transceivers. It connects directly to the SCSI bus and
generates signal timing and bus protocol in compliance with SCSI
standards.
The SCSI interface on the LSIU160 operates as an 8-bit or 16-bit
interface. It supports 8-bit or 16-bit, synchronous and asynchronous, LVD
or SE, Fast, Ultra, Ultra2, and Ultra160 SCSI protocols in various
combinations. The interface is made through connectors J3 and J4 (see
connector. External connector J3 is a shielded 68-pin HD right angle
connector exposed in the back panel bracket. LVD/SE dual mode, active
termination is provided on the LSIU160. Termination is automatically
disabled when both SCSI connectors are used. The LSIU160 supplies
SCSI bus TERMPWR through a blocking diode and a self-resetting 1.5 A
short circuit protection device. A 40 MHz oscillator is installed on the

LSIU160. This oscillator provides the clock frequency necessary to
support Ultra160 SCSI transfers of up to 160 Mbytes/s.
1.3.3 SCSI Bus Activity LED Connector
A SCSI Bus Activity LED connector indicates the status of the SCSI bus
when a LED is attached. This LED lights when the SCSI bus is
transferring information.
1.4 Benefits of Ultra160 SCSI
Ultra160 SCSI delivers data up to two times faster than Ultra2 SCSI.
Ultra160 SCSI is an extension of the SPI-3 draft standard that allows
faster synchronous SCSI data transfer rates than Ultra2 SCSI. When
enabled, Ultra160 SCSI performs 80 megatransfers per second resulting
in approximately double the synchronous data transfer rates of Ultra2
SCSI. The LSI53C1010 performs 16-bit, Ultra160 SCSI synchronous
data transfers as fast as 160 Mbytes/s. This advantage is most
noticeable in heavily loaded systems or large block size applications
such as video on-demand and image processing.
44.25 pc
The Ultra160 data transfer speed is accomplished using DT clocking. DT
clocking refers to transferring data on both polarity edges of the request
or acknowledge signals. Data is clocked on both rising and falling edges
of the request and acknowledge signals. Double-edge clocking doubles
data transfer speeds without increasing the clock rate.
1.4.1 Cyclic Redundancy Check (CRC)
Ultra160 SCSI includes CRC which offers higher levels of data reliability
by ensuring complete integrity of transferred data. CRC is a 32-bit
scheme, referred to as CRC-32. CRC is guaranteed to detect all single
bit errors, any two bits in error, or any combination of errors within a
single 32-bit range.
1.4.2 Asynchronous Information Protection (AIP)
AIP is also supported by the LSI53C1010, protecting all non-data
phases, including command, status, and messages. CRC, along with AIP,
provides end-to-end protection of the SCSI I/O.

1.5 Benefits of LVDlink Technology
To support greater device connectivity and a longer SCSI cable, the
LSIU160 features LVDlink technology, the LSI Logic implementation of
Universal LVD SCSI. LVDlink transceivers provide the inherent reliability
of differential SCSI, and a long-term migration path to faster SCSI
transfer rates.
The LVDlink transceivers reduce the power needed to drive the SCSI
bus, so that the I/O drivers can be integrated directly into the chip.
LVDlink technology lowers the amplitude of noise reflections and allows
higher transmission frequencies.
The LVDlink transceivers operate in LVD and SE modes. They also allow
the chip to detect a High Voltage Differential (HVD) signal when the chip
is mistakenly connected to external HVD transceivers. When connected,
the LSI53C1010 automatically detects the signal type, based on the
voltage detected. It automatically switches to the SE or LVD mode, as
appropriate.
Important: All bus devices must be LVD or SE. If a HVD device is
detected, the board puts the SCSI bus in the high
impedance state and shuts down.
44.25 pc
®
1.6 Benefits of TolerANT Technology
The LSI53C1010 features TolerANT technology, which includes active
negation on the SCSI drivers and input signal filtering on the SCSI
receivers. Active negation causes the SCSI Request, Acknowledge,
Data, and Parity signals to be actively driven HIGH rather than passively
pulled up by terminators.
TolerANT receiver technology improves data integrity in unreliable
cabling environments where other devices would be subject to data
corruption. TolerANT receivers filter the SCSI bus signals to eliminate
unwanted transitions, without the long signal delay associated with
RC-type input filters. This improved driver and receiver technology helps
eliminate double clocking of data which is the single biggest reliability
issue with SCSI operations. TolerANT input signal filtering is a built-in
feature of the LSI53C1010 and all LSI Logic Fast SCSI, Ultra SCSI,
Ultra2 SCSI, and Ultra160 SCSI devices.

The benefits of TolerANT technology include increased noise immunity
when the signal transitions to HIGH, better performance due to balanced
duty cycles, and improved fast SCSI transfer rates. In addition, TolerANT
SCSI devices do not cause glitches on the SCSI bus at power-up or
power-down. This protects other devices on the bus from data corruption.
When it is used with the LVDlink transceivers, TolerANT technology
provides excellent signal quality and data reliability in real world cabling
environments. TolerANT technology is compatible with both the
Alternative One and Alternative Two termination schemes proposed by
the American National Standards Institute.
1.7 Benefits of SureLINK™ (Ultra160 SCSI Domain Validation)
SureLINK represents the very latest SCSI interconnect management
solution. It ensures robust and low risk Ultra160 SCSI implementations
by extending the Domain Validation guidelines documented in the ANSI
T10 SPI-3 specifications. Domain Validation verifies that the system is
capable of transferring data at Ultra160 speeds, allowing it to
renegotiate to lower speed and bus width if necessary. SureLINK is the
software control for the manageability enhancements in the LSI53C1010.
Fully integrated in the SDMS software solution, SureLINK provides
Domain Validation at boot time as well as throughout system operation.
SureLINK extends to the Desktop Management Interface (DMI) based
System Management components of SDMS, providing the network
administrator remote management capability.
44.25 pc
SureLINK Domain Validation provides three levels of integrity checking:
Basic (level 1), Enhanced (level 2), and Margined (level 3). The basic
check consists of an inquiry command to detect gross problems. The
enhanced check sends a known data pattern using the Read and Write
Buffer commands to detect additional problems. Margined check verifies
that the physical parameters have some degree of margin. By varying
LVD drive strength and REQ/ACK timing characteristics, level 3 verifies
that no errors occur on the transfers. These altered signals are only used
during the diagnostic check and not during normal system operation.
Should errors occur with any of these checks, the system can drop back
to a lower transmission speed, on a per-target basis, to ensure robust
system operation.

2.2.6 SCSI Bus Termination
The devices making up the SCSI bus are connected serially (chained
together) with SCSI cables. The first and last physical SCSI devices
connected on the ends of the SCSI bus must have their terminators
active. All other SCSI devices on the bus must have their terminators
removed or disabled. Remember that the LSIU160 is also on the SCSI
bus—its termination is automatically enabled when it is connected to the
end of the bus.
Important: To utilize Ultra2 and faster SCSI performance, you must
only have LVD devices on the bus. Do not mix any SE
devices with LVD devices or the entire bus will drop to SE,
limiting bus performance to Ultra SCSI levels.
The peripheral device terminators are usually set with jumpers, resistor
modules, or with a switch on the peripheral. Refer to the peripheral
manufacturer’s instructions and to the user’s manual for your computer
for information on how to identify the terminator type/setting for each
device and how to set/change it.
Caution: The autoenable/disable sensing feature on the LSIU160
may enable termination erroneously if it is directly cabled to
another SCSI device or host adapter using the same
sensing method. The LSIU160 senses the presence of
SCSI devices by detecting the ground signal on conductor
50 of the SCSI cable.
44.25 pc
The LSIU160 automatically controls SCSI bus termination for three
different bus configurations, depending on how it is connected (see

2.2.7 Setting SCSI IDs
You must set each SCSI device and the host adapter to a separate SCSI
ID 0 through 15. SCSI ID 7 is the preset host adapter setting, giving it
the highest priority on the SCSI bus. If you plan to boot your computer
from a SCSI hard disk drive on the SCSI bus, that drive should have the
lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for
system performance optimization, an ID other than 0 (zero) can be used.
adapter ID using the LSI Logic SCSI BIOS Configuration Utility.
The peripheral device SCSI IDs are usually set with jumpers or with a
switch on the peripheral. Refer to the peripheral manufacturer’s
instructions and to the user’s manual for your computer to determine the
ID of each device and how to change it.
Note: You must not have any duplication of SCSI IDs on a SCSI
bus.
Step 1. Determine the SCSI ID of each device on the SCSI bus. Note
any duplications.
Step 2. Make any necessary changes to the SCSI IDs to eliminate
duplicates and record the IDs for future reference.

3.1 Overview of the SCSI BIOS Configuration Utility
The LSIU160 is loaded with LSI Logic SCSI BIOS and Configuration
Utility Version 4.16 (or greater). This section describes the process you
need to follow to change configuration settings on your board.
The SDMS SCSI BIOS provides support for the BIOS Boot Specification
(BBS), which allows you to choose which device to boot from by
selecting the priority.
34.732 pc
To use this feature, the system BIOS must also be compatible with the
BBS. If your system supports the BBS, then you will use the system
BIOS setup menu to select the boot and drive order. In the system BIOS
setup, the Boot Connection Devices menu appears with a list of available
boot options. Use that menu to select the device and rearrange the order.
Then exit to continue the boot process.
In most cases you should not need to change the default configuration
of the host adapter. You may decide to alter these default values if there
is a conflict between device settings or if you need to optimize system
performance.
There are four sets of configurations you can change. You make changes
on subordinate menus called from the Main Menu, which is opened when

All these properties are controlled by menus you access through the
configuration utility Main Menu. The Main Menu also gives an overview
of some properties of installed LSI Logic host adapter boards.
3.1.1 Starting the Configuration Utility
You can see the version number of your LSI Logic SCSI BIOS in a
banner displayed on your computer monitor during boot. If the utility is
available, the following message also appears on your monitor:
Press Ctrl-C to start LSI Logic Configuration Utility...
This message remains on your screen for about five seconds, giving you
time to start the utility. If you press “Ctrl-C,” the message changes to:
44.25 pc
Please wait, invoking LSI Logic Configuration Utility...
After a brief pause, your computer monitor displays the Main Menu of the
LSI Logic SCSI BIOS Configuration Utility.
These messages may appear during the boot process:
•
•
•
“Adapter removed from boot order, parameters will be
updated accordingly” appears when an adapter is removed from
the system or relocated behind a PCI bridge.
“Configuration data invalid, saving default
configuration!” appears if none of the information in the NVRAM
is valid.
“Found SCSI Controller not in following Boot Order List,
to Add: Press Ctrl-C to start LSI Logic Configuration
Utility...” appears when less than four adapters are in the boot
order and more adapters exist than are shown.

NonVolatile Random Access Memory (NVRAM) is available on the
LSIU160. Changes can be made and stored using this menu driven
utility.
Important: This utility is a powerful tool. If, while using it, you somehow
disable all of your controllers you can recover. Pressing
Ctrl-E after memory initialization during a reboot allows you
to re-enable and reconfigure.
Note: Not all devices detected by the Configuration Utility can be
controlled by the BIOS. Devices such as tape drives and
scanners require that a device driver specific to that
peripheral be loaded. This device driver is provided by the
device manufacturer.
3.1.2 Exiting the SCSI BIOS Configuration Utility
Since most changes only take effect after the system reboots, you must
exit properly from the Configuration Utility. The proper exit technique is
exiting the subordinate menus.

Description
CHS Mapping
Configuration
Defines how the Cylinder Head Sector (CHS) values
[SCSI Plug and Play are mapped onto a disk without pre-existing partition
Mapping / Alternate information.
CHS Mapping]
SCSI Plug and Play Mapping automatically
determines the most efficient and compatible
mapping.
Alternate CHS Mapping utilizes an alternate, possibly
less efficient mapping that may be required if a
device is moved between adapters from different
vendors.
Caution: Neither of these options has any effect after
a disk has been partitioned using the FDISK
command. The FDISKutility is a tool that the user can
use to delete partition entries, one or all of them. If
all partition entries are deleted, it is necessary to
reboot to clear memory or the old partitioning data
will be reused, thus nullifying the previous operation.
Use care to ensure that the correct disk is the target
of an FDISKcommand.
Spinup Delay
(Seconds)
Configuration
[1 to 15]
Indicates the delay in seconds between spinups of
devices attached to an adapter. Staggered spinups
balance the total electrical current load on the system
during boot. The default value is 2 seconds.
44.25 pc
Secondary Cluster
Server
Configuration
[Yes / No]
Indicates whether an adapter has one or more
devices attached that are shared with one or more
other adapters and therefore, the LSI Logic SCSI
BIOS should avoid SCSI bus resets as much as
possible.
This option allows the user to enable an adapter to
join a cluster of adapters without doing any SCSI bus
resets. This is a requirement for Microsoft Cluster
Server. The default value is No with an alternate
option of Yes.
Termination Control
<Restore Defaults>
Configuration
[Auto / Off]
If available, the field indicates whether an adapter has
automatic termination control.
Auto means that the adapter automatically
determines whether it should enable or disable its
termination. Auto is the default state unless
termination is done manually, in which case, the
configuration is Off.
Executable
Press Enter to obtain default settings.

Configuration
[Yes / No]
Indicates whether to scan for this SCSI identifier at boot
time. Utilizing this setting allows you to ignore a device.
This decreases boot time by disabling inquiry of unused
SCSI identifiers.
Set this option to No if there is a device that you do not
want to be available to the system. Also, on a bus with
only a few devices attached, the user can speed up boot
time by changing this setting to No for all unused SCSI
IDs.
Scan LUNs > 0
Configuration
[Yes / No]
Indicates whether to scan for LUNs greater than zero for
a device. LUN 0 is always queried. This option should
be used if a multi-LUN device responds to unoccupied
LUNs or if it is desired to reduce the visibility of a
multi-LUN device to LUN 0 only.
Set this option to No if you have problems with a device
that responds to all LUNs whether they are occupied or
not. Also, if a SCSI device with multiple LUNs exists on
your system but you do not want all of those LUNs to be
available to the system, then set this option to No. This
will limit the scan to LUN 0.

Indicates the maximum allowable time for completion of
a SCSI operation in seconds.
Since time-outs provide a safeguard that allows the
system to recover should an operation fail, it is
recommended that a value greater than zero be used. A
value of zero allows unlimited time for an operation to
complete and could result in the system hanging (waiting
forever) should an operation fail.

A.2 Operational Environment
The LSIU160 is designed for use in PCI computer systems with an
ISA/EISA bracket type. SDMS operates the board, but the design of the
board does not prevent the use of other software. An on-board flash
memory device is provided to allow BIOS code and open boot code
support through PCI and a serial EEPROM.
A.2.1 The PCI Interface
The PCI interface operates as a 64-bit DMA bus master. The connection
is made through edge connector J1, which provides connections on both
the front and back of the board. The signal definitions and pin numbers
conform to the PCI Local Bus Specification Revision 2.2 standard.
of the LSI53C1010 device is powered from the onboard +3.3 V regulator.
Note: The +3.3 V pins are tied together and decoupled with high
frequency bypass capacitors to ground. No current from
these 3.3 V pins is used on the board. The board derives
power from the +5 V pins, directly and through a 3.3 V
voltage regulator. The PCI +3 V/+5 V pins are used to
differentiate between a 5 V or a 3.3 V PCI environment.

Any device that conforms to the SCSI standard and is attached to the
SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI
peripherals.
A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI
bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15
for Wide SCSI). The host adapter usually gets the highest ID, (7 or 15)
giving it priority to control the bus.
SCSI SCRIPTS
A SCSI programming language that works with the SCRIPTS processor
that is embedded on the LSI53C8XX or LSI53C10XX device. These
SCRIPTS reside in host computer system memory.

SCRIPTS
Processor
The SCRIPTS processor allows users to fine tune SCSI operations with
regard to unique vendor commands or new SCSI specifications. The
SCRIPTS processor fetches SCRIPTS instructions from system memory
to control operation of the LSI53C8XX or LSI53C10XX device.
SDMS
Storage Device Management System. An LSI Logic software product that
manages SCSI system I/O.
Single-Ended
SCSI
A hardware specification for connecting SCSI devices. It references each
SCSI signal to a common ground. This is the most common method (as
opposed to differential SCSI which uses a separate ground for each
signal).
STA
SCSI Trade Association. A group of companies that cooperate to
promote SCSI parallel interface technology as a viable mainstream I/O
interconnect for commercial computing.
SureLINK
The domain validation method developed and used by LSI Logic.
SureLINK provides three levels of integrity checking: Basic (level 1),
Enhanced (level 2), and Margined (level 3).
Synchronous
Data Transfer
One of the ways data is transferred over the SCSI bus. Transfers are
clocked with fixed frequency pulses. This is faster than asynchronous
data transfer. Synchronous data transfers are negotiated between the
SCSI host adapter and each SCSI device.

System BIOS
TolerANT
Controls the low-level POST (Power-On Self-Test), and basic operation
of the CPU and computer system.
A technology developed and used by LSI Logic to improve data integrity,
data transfer rates, and noise immunity, through the use of active
negation and input signal filtering.
Ultra SCSI
A standard for SCSI data transfers. It allows a transfer rate of up to
20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit
SCSI bus. SCSI Trade Association (STA) supports using the term “Ultra
SCSI” over the older term “Fast-20”.
Ultra2 SCSI
A standard for SCSI data transfers. It allows a transfer rate of up to
40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a
16-bit SCSI bus. SCSI Trade Association (STA) supports using the term
“Ultra2 SCSI” over the term “Fast-40”.

VDE
Voluntary Control Council for Interference.
Verband Deucher Elektroniker (Association of German Electrical
Engineers).
Virtual Memory
Wide SCSI
Space on a hard disk that can be used as if it were RAM.
A SCSI-2 feature allowing 16-bit or 32-bit transfers on the SCSI bus. This
dramatically increases the transfer rate over the standard 8-bit SCSI bus.
Wide Ultra SCSI The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 40 Mbytes/s.
Wide Ultra2
SCSI
The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 80 Mbytes/s.
Word
A two byte (or 16-bit) unit of information.
