 +---+---+---+-------+---------------------------------------------+

 NOTE
 In the table below, a 0 indicates that the jumper is removed, a 1
 indicates that the jumper is installed, and an X indicates that the
 jumper setting does not matter.


 CS  Cable Select Jumper
 -----------------------
 When two Fireball 540/1080AT hard disk drives are daisy-chained
 together, they can be configured as Master and Slave by using the CS
 jumper or by using the DS jumpers. To configure the drive as a
 Master or Slave with the CS feature, the CS jumper is installed.

 Once you install the CS jumper, the drive is configured as a Master
 or Slave by state of the Cable Select signal, which is pin 28 at the
 IDE-bus interface connector. Please note that pin 28 is a vendor-
 specific pin that Quantum is using for a specific purpose. More than
 one function is allocated to CS, according to the ATA CAM specifica-
 tion. If pin 28 is 0 (grounded), the drive is configured as a Master.
 If it is a 1 (high), the drive is configured as a Slave. In order to
 configure two drives in a Master/Slave realationship using the CS
 jumper, you need to use a cable that provides the proper signal
 level at pin 28 of the IDE bus connector. This allows two drives to
 operate in a Master/Slave realtionship according the drive cable
 placement.


 Drive Select Jumper
 -------------------
 You can also daisy-chain two drives on the IDE bus interface by using
 their Drive Select (DS) jumpers. To use the DS feature, the CS jumper
 must be removed.

 To configure a drive as the Master (Drive 0), a jumper must be
 installed on the DS pins.

 The Quantum Fireball 540/1080AT hard disk drives are shipped from the
 factory as a Master (Drive 0 - DS jumper installed). To configure a
 drive as a Slave (Drive 1), the DS jumper must be removed. In this
 configuration, the spare jumper removed from the DS position may be
 stored on the SP jumper pins.

 NOTE
 The order in which drives are connected in a daisy chain has no
 significance.


 Slave Present Jumper (SP)
 -------------------------
 In combination with the current DS or CS jumper settings, the Slave
 Present (SP) jumper implements one of two possible configurations:

  - When the drive is configured as a Master (DS jumper installed or
    CS jumper installed and the Cable Select signal set to 0) the SP
    jumper indicates to the drive that a slave is present. The SP
    jumper should be installed on the Master drive only if the Slave
    drive does not use the Drive Active/Slave Present (DASP-) signal
    to indicate its presence.

  - When the drive is configured as a Slave (DS jumper not installed)
    the SP jumper position is used to store the DS jumper and will
    have no effect.

 If an error is encountered during the self-seek test, the test
 terminates.


 J1A/B/C  DC Power/Interface Connector
 -------------------------------------
 The drive's DC power can be applied to either section A or B.
 The IDE-bus interface (40-pin) uses section C.

 Orientation
 -----------
 The mounting holes on the Quantum Fireball 540/1080AT 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. A maximum screw
 length of 0.25 inches may be used on the side mounting locations
 when a bracket of 0.040 inches minimum thickness is included.


 IDE BUS ADAPTER
 ---------------
 There are two ways you can configure a system to allow the Quantum
 Fireball 540/1080AT hard disk drive to communicate over the IDE bus
 of an IBM or IBM-compatible PC:

  1. Connect the drive to a 40-pin IDE bus connector (if available) on
     the motherboard of the PC.

  2. Install an IDE-compatible adapter board in the PC and connect the
     drive to the adapter board.


 40-Pin IDE Bus Connector
 ------------------------
 Many of the later design PC motherboards have a built-in 40-pin IDE
 bus connector that is compatible with the 40-pin IDE interface of the
 Quantum Fireball 540/1080AT hard disk drive. If the motherboard has
 an IDE connector, simply connect a 40-pin ribbon cable between the
 drive and the motherboard.


 Adapter Board
 -------------
 If your PC motherboard does not contain a built-in, 40-pin IDE bus
 interface connector, you must install an IDE bus adapter board and
 connecting cable to allow the drive to interface with the mother-
 board. Quantum does not supply such an adapter board, but they are
 available from several third-party vendors.


 Clearance
 ---------
 Clearance from the drive - except mounting surfaces - to any surface
 must be 0.05 inches (1.25 mm) minimum.


 Ventilation
 -----------
 The Quantum Fireball 540/1080AT hard disk drives operates without a
 cooling fan, provided the ambient air temperature does not exceed
 131*F (55*C).


 DC Power (J1 A and B)
 ----------------------
 The recommended mating connectors for the +5VDC and +12VDC input
 power are listed above.

 J1 A  4-Pin Connector:      AMP P/N 1-480424-0

       Loose piece contacts: AMP P/N VS 60619-4

       Strip contacts:       AMP P/N VS 61117-4

 J1 B  3-Pin Connector:      Molex P/N 5484 39-27-0032

 Power can be supplied to either J1 section A or J1 section B.
 Labels indicates the pin numbers on the connectors.


 Power Sequencing
 ----------------
 You may apply the power in any order or manner, or short or open
 either the power or power return line with no loss of data or damage
 to the disk drive. However, data may be lost in the sector being
 written at the time of power loss. The drive can withstand transient
 voltages of +10% to -100% from nominal while powering up or down.


 IDE-Bus Interface Connector (J1 C)
 ----------------------------------
 On the Fireball 540/1080AT hard disk drive, the IDE-bus interface
 cable connector (J1 section C) is a 40-pin Universal Header.

 To prevent the possibility of incorrect installation, has been keyed
 by removing Pin 20, which ensures that a connector cannot be
 installed upside down.


  For Systems with a Motherboard IDE Adapter
  ==========================================
  You can install the Fireball 540/1080AT hard disk drive in an
  AT-compatible system that contains a 40-pin AT-bus connector on the
  motherboard.

  To connect the drive to the motherboard, use a 40-pin ribbon cable
  18 inches in length or shorter. Ensure that pin 1 of the drive is
  connected to pin 1 of the motherboard connector.


  For Systems with an IDE Adapter Board
  =====================================
  To install a Fireball 540/1080AT hard disk drive in an
  AT-compatible system without a 40-pin, IDE bus connector on its
  motherboard, you need a third-party IDE-compatible adapter board.

  Adapter Board Installation
  --------------------------
  Carefully read the manual that accompanies your adapter board before
  installing it. Make sure that all the jumpers are set properly and
  that there are no addressing or signal conflicts. You must also
  investigate to see if your AT-compatible system contains a
  combination floppy and hard disk controller board. If it does, you
  must disable the hard disk drive controller functions on the
  controller board before proceeding.

  Once you have disabled the hard disk drive controller functions on
  the floppy/hard drive controller, install the adapter board. Again,
  make sure that you have set all jumper straps on the adapter board
  to avoid addressing and signal conflicts.


  Connecting the Adapter Board and the Drive
  ------------------------------------------
  Use a 40-pin ribbon cable to connect the drive to the board.

  1. Insert the 40-pin cable connector into the mating connector on
     the adapter board. Make sure that pin 1 of the connector matches
     with pin 1 on the cable.

  2. Insert the other end of the cable into the header on the drive.
     When inserting this end of the cable, make sure that pin 1 of
     the cable connects to pin 1 of the drive connector.

  3. Secure the drive to the system chassis by using the mounting
     screws.


 Base Casting Assembly
 ---------------------
 A single-piece aluminium-alloy base casting provides a mounting sur-
 face for the drive mechanism and PCB. The base casting also acts as
 the flange for the DC motor assembly. To provide a contamination-free
 environment for the HDA, a gasket provides a seal between the base
 casting and the metal cover that enclose the drive mechanism.


 Air Filtration
 --------------
 The Fireball 540/1080AT hard disk drives are Winchester-type
 drives. The heads fly very close to the media surface. 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, then seals the drive with a metal cover. When the
 drive is in use, the rotation of the disk forces the air inside of
 the drive through an internal filter.


 DC Motor Assembly
 -----------------
 Integral with the base casting, the DC motor assembly is a fixed-
 shaft, brushless DC spindle motor that drives the counter-clockwise
 rotation of the disks.


 Electrical Characteristics
 --------------------------
 All signals are transistor-transistor logic (TTL) compatible - with
 logic 1 greater than 2.0 volts and less than 5.25 volts; and logic 0
 greater than 0.0 volts and less than 0.8 volts. Neither the adapter
 board, motherboard interface, or drives require terminating
 resistors.


 Drive Cable and Connector
 -------------------------
 The hard disk drive connects to the host computer by means of a
 cable. This cable contains a 40-pin connector that plug into the
 drive, and a 40-pin connector that plugs into the host computer. At
 the host end, the cable plugs into either an adapter board residing
 in a host expansion slot or an on-board IDE adapter.

 If two drives are connected by a cable with two 40-pin drive
 connectors, the cable-select feature of the Fireball 540/1080AT
 automatically configure each as drive 0 or drive 1 depending on the
 configuration of pin 28 on the connector.

QUANTUM   ATA TIPS


 Comparing the Fast ATA and Enhanced IDE Disk Drive Interfaces
 -------------------------------------------------------------
 Why are Fast ATA and Fast ATA-2 Important?
 Faster data transfer rates are important because a computer is
 only as fast as its slowest component. Today's 486, Pentium, and
 PowerPC-based computers offer processor speeds many times faster
 than only two years ago. Bus speeds have also increased with the
 inclusion of 32-bit VL and PCI local buses, which have a maximum
 data transfer rate of 132 MB/second.

 Faster buses mean that data can be transferred from the storage
 device to the host at greater speeds. Fast ATA and Fast ATA-2 allow
 disk drives to store and access this data faster, thus enhancing the
 other high-speed components in the system and removing the
 bottleneck associated with older ATA/IDE drives. In short, Fast
 ATA helps bring very high performance to desktop PC systems.

 In addition, when compared to SCSI, Fast ATA is the least expensive
 way to achieve faster disk drive data transfer rates and higher
 system performance. The implementation of Fast ATA through system
 BIOS provides performance without incremental hardware co sts.
 Older systems can support Fast ATA using an inexpensive host
 adapter.

 Fast ATA and Fast ATA-2 are easy to implement in either VL or PCI
 local bus systems. The hardware connection can be made using a
 standard 40-pin ATA ribbon cable from the drive to the host
 adapter. Direct connection to the motherboard further eases
 integration when provided by the motherboard supplier.

 Once connected, the high data transfer capabilities of Fast ATA can
 be enabled through the data transfer options found in most CMOS BIOS
 setup tables.  Newer versions of BIOS provide automatic configuration
 for Fast ATA drives.

 Fast ATA can improve efficiency by allowing more work to be
 completed in less time because the computer moves data faster.
 Graphic, multimedia, and audio/visual software users will benefit
 most because the speed of those applications, which work with large
 blocks of data, are transfer-rate dependent.

 The Fast ATA and Enhanced IDE interfaces both use the local bus to
 speed data transfer rates. Enhanced IDE also uses the same PIO modes
 as Fast ATA, although a data transfer rate equal to the PIO mode 4
 rate has not been announced for Enhanced IDE. The major differences
 between Fast ATA and Enhanced IDE are that the latter includes
 three distinct features in addition to fast data transfer rates.
 The additional features of Enhanced IDE are as follows:

 High-capacity addressing of ATA hard drives over 528 MB  -
 a BIOS and device driver function.

 Dual ATA host adapters supporting up to four hard disk drives per
 computer system  -  a function of BIOS, operating system, and host
 adapter, not the drive.

 Support for non-hard disk drive peripherals such as CD-ROMs -
 a function of BIOS and the operating system, not the drive

 Each of these features supports improved functionality at a system
 level, a positive development for the industry and end users.
 However, support for all three features requires an extremely high
 degree of integration and revisions to operating systems and hard-
 ware, in addition to BIOS changes. Specific support is required not
 only for the storage peripherals but also for host adapters, core
 logic, the system bus, BIOS, and operating systems - virtually every
 major block of PC architecture.

 There is no central industry-supported standard that controls the
 features of Enhanced IDE. With no standard, some products sold as
 "Enhanced" may provide only one of the three features of Enhanced
 IDE. For example, fast data transfer rate support is be coming
 standard on mid-range and high-end local bus systems. This single
 feature could satisfy the users immediate requirements without the
 need for the other features of Enhanced IDE.

 In the future, if the same system is upgraded to add the remaining
 features of Enhanced IDE, users may be forced to purchase an Enhanced
 IDE package that contains a feature already installed. This could
 result in unnecessary costs, integration conflicts, and in-
 compatibility with original factory implementations.

 Fast ATA, on the other hand, represents only the fast data transfer
 rates for ATA hard drives (support for PIO mode 3 or 4 and DMA mode
 1 or 2).  Fast ATA and Fast ATA-2 data transfer rates can be easily
 achieved when the system BIOS and hard drive suppo rt the PIO and
 DMA protocols.

 BIOS that supports Fast ATA does not necessarily support high-
 capacity addressing, dual host adapters or non-hard drive
 peripherals. But these features are being introduced independently
 by system manufacturers in order to compete in the PC marketplace.

 All of Quantum's disk drives designed for PCs now support Fast ATA,
 and new products with Fast ATA support will be introduced in early
 1995. The drives are also fully backward compatible with older ATA/
 IDE (non-Fast ATA) BIOS.

 The Quantum drives support both the Extended CHS (Cylinder Head
 Sector) and LBA (Logical Block Address) addressing methods in
 overcoming the 528 MB DOS capacity barrier. Quantum drives can also
 be used with dual host adapters.

 Finally, there are no incompatibilities with Quantum hard drives
 that would prevent computer systems from supporting non-hard drive
 peripherals.

 Quantum drives that support Fast ATA include the following families:

 Quantum ProDrive LPS 170/210/340/420
 Quantum ProDrive LPS 270/540
 Quantum Maverick 270/540
 Quantum Lightning 365/540/730

 Fast ATA and Fast ATA-2 are important technologies that can take
 advantage of the performance provided by the latest high-speed
 microprocessors and bus architectures. The high-speed interfaces
 are based on industry standard specifications and are the least
 expensive way to achieve faster disk drive data transfer rates.
 Fast ATA is not a group of features that requires an extremely
 high level of integration, and only represents the fast data transfer
 rates for ATA hard drives (PIO mode 3 or 4 and DMA mode 1 or 2).
