Note: In the 40/80AT mode, PDIAG- is not used; otherwise, it is
always used.
DS Drive Select Jumper
-----------------------
x CLOSED Single drive or MASTER (Drive 0)
OPEN SLAVE (Drive 1)
You can daisy-chain two drives on the AT-bus interface by using
their Drive Select (DS) jumpers to configure one drive as the Master
and the other as the Slave.
Note: The order in which drives are connected in a daisy chain has no
significance.
SP Slave Present Jumper
-------------------------
In combination with the current DS jumper settings, the Slave Present
(SP) jumper implements one of two possible configuratons:
When the drive is configured as a Master - that is, with the DS
jumper installed - the SP jumper should be installed on the Master
drive only if the Slave drive does not use the Drive Active/Slave
(DASP-) signal to indicate its presence.
When the drive is cnfigured as a Slave - that is, without the DS
jumper installed - the SP jumper enables the self-seek test. When
power is applied to the drive with the self-seek test enabled, the
drive executes seeks in a butterfly pattern.
During the self-seek test, the LED remains on whle the test proceeds
without error. If the test encounters a seek error, the test
terminates and the LED flashes continuously until the SP jumper is
removed.
DM Drive Mode Jumper
---------------------
When the Drive Mode jumper is installed, the drive is in the ProDrive
40/80AT-compatible mode and can communicate with a ProDrive 40/80AT
hard disk drive. In this mode, the drive does not use the PDIAG-
signal to control Master/Slave communications. The configuration of
the DS and SP jumpers determines whether the drive is the Master
or the Slave.

---------------------------------------------------------------------
Adapter Board Jumper Options
============================
Four jumper pins on the adapter board - labeled J2 through J5 - have
the function described below.
J2 Enables the drive's interrupt logic to control IRQ14
(Interrupt Request 14). This option provides compatibility
with systems in which the BIOS does not read the STATUS Register
when the drive issues an interrupt. In such cases, the drive
might fail to transmit the interrupt to the system.
- A jumper from the center pin J2 to E3 enables transmission of
an interrupt every time the drives goes busy.
- A jumper from the center pin J2 to E4 gates the interrupt from
the drive and transmits it directly to the AT bus. This is the
default setting.
J3 These pins should always remain open, with no jumper installed.
J4 This jumper should generally remain open. A jumper should be
installed here only when installing the adapter board
in a system that uses the Chips & Technologies chip set. This
chip set runs the I/O bus faster than the standard 12 Mhz, one
wait state.
J5 Enables secondary interface selection on a second adapter board
installed in a system. When a jumper is installed here,
drives connected to the adapter board respond to commands
transmitted via the secondary address, 170H-177H. Standard BIOS
versions do not support secondary addresses. Therefore, you must
write a custom driver to implement a secondary interface.
Note: A second adapter board is supported only when both adapter
boards are Quantum boards.

Notes on Installation
=====================
Mounting
--------
The mounting holes on the ProDrive LPS 80AT hard disk drive
allow the drive to be mounted in any orientation. For mounting, #6-32
UNC screws are recommended.
Caution: The PCB is very close to the mounting holes. Do not
exceed the specified length for the mounting screws. The specified
screw length allows full use of the mounting-hole threads, while
avoiding damaging or placing unwanted stress on the PCB. To avoid
stripping the mounting-hole threads, the maximum torque applied to
the mounting screws must not exceed 8 inch-pounds.
Ventilation
-----------
The ProDrive LPS 80AT hard disk drives operates without a cooling
fan, provided the ambient air temperature does not exceed 122*F
(50*C). Any user-designed cabinet must provide adequate air circula-
tion, to prevent the maximum temperature being exceeded.
J1 AT-Bus Interface Connector
-----------------------------
On the ProDrive LPS 80AT hard disk drive, the AT-bus interface
cable connector (J1) is a 40-pin Universal Header.
To prevent the possibility of incorrect installation, you should be
keyed by removing pin 20. This will ensure that the connector cannot
be installed upside down. All signal are relative to Pin 20.
For the mating J1 connector, recommended cable connectors include AMP
receptacle P/N 1-499506-0, with strain relief; P/N 1-746193-0, with-
out strain relief; or an equivalent. To key the cable connectors, you
must plug the hole that corresponds to pin 20.
Other recommended part numbers for the mating connector include:
40-Pin Connector 3M 3417-7000 or equivalent
Strain Relief 3M 3448-2040 or equivalent
Flat Cable (Stranded 28 AWG) 3M 3365-40 or equivalent
Flat Cable (Stranded 28 AWG) 3M 3517-40 (shielded) or equivalent
Adapter Board Installation
--------------------------
The adapter board is a half-size board. You can install it in any
available 16-bit slot in an IBM PC-AT or compatible personal
computer. Before installing the adapter board, make sure that no
other hard drive controller resides at the primary hard drive
address, 1F0H-1F7H.
If a combination floppy and hard disk drive controller is present,
its hard disk drive controller functions must be disabled.
To disable the hard disk drive controller functions, follow these
instructions:
On a Western Digital WD1002-WA2 or WD1003-WA2 floppy/hard disk drive
controller card:
- Do not install jumpers on pins E5 and E6.
Install jumpers on pins E4 and E5 to ensure that the controller
card resides at the secondary address, 170H-177H, rather than at
the primary address, 1F0H-1F7H.
- Move the card from a 16-bit I/O slot to an 8-bit slot to
disconnect the IRQ14 output driver.
On a Data Technology Corporation (DTC) floppy/hard disk drive
controller card:
- Install a jumper on pins W3.
- Move the card from a 16-bit I/O slot to an 8-bit slot to
disconnet the IRQ14 output driver,
Once you have disabled hard disk drive controller functions on the
card, install the adapter board in a 16-pin slot.
Connecting the Adapter Board and the Drive
------------------------------------------
Use the ribbon cable supplied with the adapter board to connect the
drive to the board. To ensure that the cable is plugged into the
adapter board and the drive correctly, there is a red wire at one
edge of the cable. To connect the drive to the board:
1. Note the number 1 printed on the board next to the header. When
inserting the cable connector into the header on the adapter
board, make sure the red wire on the cable is at the side of the
header labeled 1.
2. When inserting the other end of the cable connector into the
header on the drive, make sure the red wire on the cable is at
the inside edge of the header, next to the J3 power connector.
To complete the installation of the drive, secure it to the system
chassis by using the mounting screws.
J3 DC Power Connector
---------------------
The drive's DC power connector is a 4-pin Ranoda Electronics
Connector (06300010-04-1) or equivalent, mounted on the back edge of
the Printed Circuit Board (PCB).
Recommended connectors and their numbers:
4-pin connector AMP P/N 1-480424-0 or equivalent
Loose-piece contacts AMP P/N 61173-4 or equivalent
Strip contacts AMP P/N 350078-4 or equivalent
Air Filtration
--------------
Low Profile Series hard drives are Winchester-type drives. The heads
fly very close to the media surface, at a nominal flying height of
4 microinches. Therefore, it is essential that the air
circulating within the drive be kept free of particles. Quantum
assembles the drive in a Class-100, purified-air environment, sealing
the drive mechanism under a metal cover. When the drive is in use,
the rotation of the disks forces the air inside the drive through an
internal filter.
Electrical Characteristics
--------------------------
All signals are TTL-compatible - with logic one greater than 2.0
volts and less than 5.25 volts; and logic zero, greater than 0.0
volts and less than 0.7 volts. Neither the adapter board nor the
drives require terminating resistors.
AT-Bus Interface Characteristics
--------------------------------
The AT-Bus interface supports one or two hard drives per adapter
board and a maximum of two adapter boards - or a maximum of four
drives. When more than one drive is present, a master/slave
relationship exists between the two drives. The host always maintains
control of the bus - no arbitration occurs.

QUANTUM PRODRIVE LPS 80 AT PRODUCT MANUAL 6/11/91
General Description
-------------------
Quantum's ProDrive Low Profile Series (LPS) 80AT hard disk drives are
a part of a family of high-performance, 1-inch-high hard disk drives
manufactured to meet the highest product quality standards. ProDrive
LPS hard disk drives use nonremovable, 3 -inch hard disks, and are
available with a Small Computer System Interface (SCSI) or Advanced
Technology (AT) interface.
The ProDrive LPS 80AT hard disk drives feature an embedded AT
drive controller and use AT commands to optimize systems performance.
Because the drive manages media defects and error recovery
internally, these operations are fully transparent to the user.

Preventive Maintenance
----------------------
The ProDrive LPS 80AT hard disk drive requires no preventive
maintenance.
Defect Detection
----------------
At the sector level, any discrepancy between recorded data and re-
covered data constitutes a data error. In high-density digital re-
cording systems, it is necessary to use an error-detection and
correction scheme to increase the reliability of the system.
Data errors are either soft- not readily repeatable on retries - or
hard - repeatable with high probability. The signal-to-noise ratio of
the system affects the occurrence of soft errors, which present
marginal conditions of the media, heads, or read/write circuitry.
Hard errors occur due to defects, pits, scratches, or thin spot in
the media. The drive can skip, or not use, defective sectors on the
media for data storage.
Defect Management
-----------------
Factory Found Defects
At the factory, Quantum scans the disks for defective sectors and de-
allocates sectors containing defects prior to shipment. The drive re-
cords a primary defect list that contains the locations of all
factory-found defective sectors in a reserved cylinder on the disk.
In-line sparing skips each factory-found defect and shifts
subsequent sectors on the track to sequential sectors. One sector at
the end of each cylinder is a spare, or replacement sector. The drive
allocates spare sectors as required to maintain the proper number of
blocks per cylinder.
