 Jumper Setting
 ==============

 Master/Slave Configuration
 --------------------------
 By using optional jumper J2 beside the interface connector, two units
 can be connected on a cable in a daisy chain.
 When J2 is open, the drive runs as master drive. When closed, it acts
 as slave drive. In case of two drive connection, one should be a
 master and another should be a slave. In case of single drive
 connection, it should be defined as master.

 Both master and slave drive are allocated onto same I/O area and
 identified by Drive bit in DRVH register. Host system writes into
 register on both drives but reads register only from a selected
 drive.

 Only the selected drive can execute the command except Diagnose
 command. Diagnose command is executed on both drives and the result
 of slave drive is transferred  to master drive through PDIAG line.
 Master drive reports both results to host system.


 Interface Pin 28 -MASTER/+SLAVE
 -------------------------------
 The interface pin 28 has the same function as Option Jumper J2.
 Definition of Master/Slave should be done either by this pin or J2.
 If J2 is plugged for Master, this line does not affect to the
 definition. This selection is done by Toshiba Specific command.

 The drive may be installed in 4 kinds of the of the orientation.
 The drive can be inclined   15 degree in each orientation.


 Screwing
 --------
 Four screws should be tightened equally with 0.3 mm torque. The depth
 should be 3.00mm min. 4.0mm max. (Screws 4-M3).


 Installation
 ------------
 The drive should be mounted carefully on th esurface of 2.0mm
 flatness or less to avoid excessive distortion. And some space should
 be kept under the PCB to get enough air flow and to avoid any
 mechanical interference when receiving shock or vibration. It is
 important to check enough for safe design to prevent short-circuit
 under any circumstances.

 General Description
 -------------------
 The MK1522FCV comprises a series of intelligent disk drives, herein-
 after referred to as the MK1522FCV or simply as the drive.

 The drive features an IBM PC-AT embedded controller that requires a
 simplified adapter board for interfacing to an AT or AT compatible
 bus. The drives employ Winchester technology and a closed loop servo
 control system to realize recording density of more than 370kbits/mm
 and average access time of 15 msec with highest reliability of
 150,000 hours for MTTF (Mean Time for Failure).

 It features smallest and lightest drive with 12.7mm height half foot-
 print of market standard 3.5 inch-type micro FDD and 140 grams of
 weight.

 The MK1522FCV consists of an HDA (Head Disk Assembly) and a printed
 circuit board. The HDA is a sealed module and contains a disk spindle
 assembly, a head actuator assembly and an air filtration system.
 Reliability is enhanced through the use of Winchester technology. The
 actuator is a rotary voice coil motor and provides high-speed access.

 The disk is driven dirctly by a DC spindle motor. Air filtration is
 provided by means of a high performance air filtration system using
 both breather and circulation filters.

 The drive provides a carriage lock mechanism which is activated
 automatically when power is down, thus preventing head/media damage
 during non-operating or transportation conditions.

 The printed circuit board is located externally to the HDA and
 contains all the electric circuitries necessary to operate the drive
 except the head drivers. This board contains the power supply and
 interface signal connectors. Only the head control IC's are located
 within the HDA. The circuitries perform the following functions:
 - Read/Write, Task File Control, Spindle Motor Control, Seek and
   Head Positioning Servo Control and Abnormal Condition Detection.
