 SW1  I/O channel ready signal output
 ------------------------------------
       1   ON     Output to pin 27
 x     1   OFF    IORDY output is disabled

 Specify wether to output the IORDY signal to pin 27 of the HOST
 interface. When the data transfer rate of the host is very high
 (around 7.4MB/s), the IORDY signal is output to synchronize data
 transfer by inserting wait states.

                       always 7 bytes regardless of the setup of
                       the host.
 x     4   OFF  4 Byte The number of ECC bytes in LONG mode depends
                       on the setup done with the SET FEATURES com-
                       and. The default setup after power-on is 4

 If the drive is installed in any of the above three installation
 directions, the level deviation must not exceed 5*.

 Never install PCA to the top!


 Ambient temperature
 -------------------
 The operating temperature range for the IDD in a cabinet is specified
 at a distance of 3 cm from the IDD. Design the air flow in the cabi-
 net to keep.
 Pay attention to the air flow to prevent the DE surface temperatue
 from exceeding 65*C.
 The air circulation in the cabinet must be designed so that the PCA
 side of the IDD is particularly cooled.


 Multi-drive connection
 ----------------------
 Up to two IDDs are connectable.

 Note: To use a daisy-chain configuration (2-drive system), the disk
 drives must be connected to an M261xT series machine or an ATA-com-
 patible machine in principle. Operation cannot be assured for daisy-
 chain configurations with other machines.

 Cable requirements
 ------------------
 The cable of twisted pairs and neighboring line separated individu-
 ally is not allowed to use for the host interface cable. It is
 because that the location of signal lines in these cables is not
 fixed, and so the problem on the crosstalk among signal lines may
 occur.

 Cable length: 0.5m Max.


 External operator panel connector
 ---------------------------------

 CN5  So that the front panel LEDs can be mounted externally, the
      disk drive has an external operator panel connector. The ex-
      ternal LED indication is the same as the LED indication on the
      front panel of the disk drive.

 Media Defect
 ============
 Defect sectors are replaced with alternates when the disk is format-
 ted prior to shipment from the factory (low level format). Thus, the
 host sees a defect-free device. Alternate sectors are automatically
 accessed by the disk drive. The user need not be concerned with
 access to alternate sectors.

 Known defects, for which alternative blocks can be assigned, are not
 included in the error rate count. It is assumed that the data blocks
 to be accessed are evenly distributed on the disk media.


 Drive BIOS specification
 ========================
 The disk drive uses constant density recording technology (all
 cylinders are classified into four areas and the recording density
 varies in each area). The number of sectors/track varies with the
 area. Therefore, the disk drive constantly performs logical/physical
 translation (emulation) and the host must access the disk drive
 according to the BIOS specifications (logical parameters).

 The number of sectors/track and the number of heads in the BIOS
 specifications are defined by the INITIALIZE DRIVE PARAMETERS (or
 SET PARAMETERS) command from the host.

 Table 6.1 describes the BIOS specifications that allow the physical
 capacity of the disk drive to be used most effeciently. The disk
 drive has a low-level format with these parameters as shipped from
 the factory.

           Table 6.1          |M2622T|M2623T|M2624T|
           -------------------+------+------+------+
           Number of cylinders|1013  |1002  | 995  |
           Number of heads    |  10  |  13  |  16  |
           Sectors/track      |  63  |  63  |  63  |
           -------------------+------+------+------+
           Total capacity     | 326MB| 420MB| 513MB|

 IF able to change the fixed disk parameter table in the BIOS, the
 user can select parameters and incorporate them into the BIOS speci-
 fications. However, the selected parameters must satisfy the capaci-
 ties listed in Table 6.1.

 It is also possible, to select items (within the capacity of Table
 6.1) from the existing drive type table in the BIOS of the system.
 The disk drive operates as a device of the capacity of the selected
 drive type (parameter).


 Low-Level Format
 ================
 A low-level format is executed from the factory with the parameters
 listed in Table 6.1.

 The disk is formatted such that defects are invisble to the host.

 Tips & Hints about ICP controllers and other peripherals
 ========================================================

 Tagged queues and Fujitsu M 26xx harddisks
 ------------------------------------------
 Fujitsu Harddisks of the M26XX series do not support the SCSI-II
 feature tagged queues. You should disable this feature in the
 initialize disks menue of the GDTSetup program. An inquiry command
 shows, that the harddisk supports tagged queues (this is why you can
 enable it in the GDTSetup) but this is not true as stated by Fujitsu
 Germany.
