-------------------1GB Disk Drives
----------------------------------------| GENERAL INSTALLATION TIPS |
--------------------------Cooling
------This drive requires airflow in order to fulfil its reliability
performance.
Please refer to Environmental section of the 0662 Hardware Disk
Drive product specification for full details of the maximum allowable
temperatures and measurement points.
Operation at excessive temperatures will void the drive warranty.
Integration into using System
----------------------------THE DISK ENCLOSURE IS NOT AT GROUND POTENTIAL
The mounting bushes are insulated from the drive. Any user mounting
scheme must not result in the disk enclosure being shorted to ground.
Drive malfunction will result if this occurs.
The correct length screws must be used (3.8mm penetration).
torque values must not be exceeded (0.45Nm), (See Below).
Maximum
Torque Specification
-------------------The present torque specification for the mounting screws is at 0.8Nm.
This level has resulted in several insert related problems. Thermal
cycling testing and high stress vibration testing performed shows
that the required amount of torque on the mounting screws to be
0.45Nm (4 in-lb).
So, we plan on making the change to 0.45Nm (4 in-lb).
for all types of inserts for all mounting holes.
This level is
In March 1994, there will be an EC to change the inserts from plastic
to metal. This will not change the form or fit, and will improve
function. This insert will still require the same torque setting of
0.45Nm (4 in-lb).
Fast SCSI
Page 1
0662-001.txt
--------The ANSI SCSI committee recommend that fast SCSI devices (such as
0662) must have cable lengths of less than 3 meters and must use
active terminators.
0662 has onboard active terminators which are jumper selectable.
Mode Select Parameters
---------------------One of the many advantages of the SCSI interface is the provision of
user-programmable (mode select) parameters to allow devices to be
customized and optimized.
These parameters are fully described in the 0662 functional specification. Further advice is available from IBM OEM Technical Support.
Compatibility
------------Testing should be carried out to ensure that the drive is fully
compatible with the using system.
System BIOS, Operating System, Device drivers and interface card
BIOS/ characteristics can affect the ability to attach the drive to
the system. All need to be verified jointly as compatible with the
drive.
----------------------------| SCSI ATTACHMENT INFORMATION |
----------------------------Synchronous Data Transfer Requests
---------------------------------In the default (shipped) setting, the drive initiates the negotiation
for synchronous data transfer rate during the initialization sequence.
(Synchronous Data Transfer Request - SDTR). This may cause problems
with some SCSI controller cards which do not conform to the ANSI SCSI
specification.
The drive synchronous data transfer request may be switched off by
jumpering the 'Disable T.I. sync negotiations' jumper.
The SCSI controller will then negotiate with the drive for the highest
common bus speed.
Idle Time Functions
------------------The 0662 has advanced self-diagnostic features. If this is not
supported in the specific application, the time taken to update the
drive's internal status tables may cause problems, especially in high
speed or very long data transfers. Mode select Page 0 Byte 5 Bit 0
(LITF) will disable the main idle time features when set to "1" (see
functional specification).

Spitfire S12 attachment to Apple Quadra 800
1.0 Problem Description
The standard software coming with the Apple Quadra 800 does not
reliably recognize the IBM 0662 S12 as a valid drive, neither as
a secondary nor as a bootable drive. Even when using a third
party device driver, the installation of the Apple system will not
be completed successfully. Also during start-up, the IBM drive
occasionally spins down and does several resets.
Page 5
0662-001.txt
2.0 Problem Solution
2.1 Installing the S12 as a secondary drive
To work properly in a Apple system, there is a special micro code
(Release version 2.2) for the 0662. This micro code can be downloaded to a Generic OEM 0662 S12 (PN 45G9466) using an Adaptec
SCSI controller and the CODEUPDT software, or by ordering a special
version (PN 45G9504) of the S12. 45G9504 will shortly become the
standard OEM p/n, attachable to all platforms which meet SCSI 2.
Installing the drive with the following jumper settings:
- Auto Start
- SCSI ID = 1
For formatting and partitioning the drive, a third party device
driver is necessary:
Disk Manager MAC
V.2.43 for systems 7.0.1 by OnTrack
After successful completion, the drive will be recognized by the
Apple system. It could happen that after a SHUTDOWN and a restart,
the Apple system will not recognize the drive anymore. To overcome
the problem, a RESTART (soft reboot) is necessary.
2.2 Installing the S12 as a boot drive
Now the first drive must be removed and the 0662 settings have to
be set to:
- Auto Start
- Disable Unit Attention
- Set Active Termination
- SCSI ID = 0
After starting the system, insert the "Install me first" disk and
follow the instructions, e.g.: select "Switch Disk" and select the
hard disk.
Now the 0662 will work as the boot drive.

-----------INSTALLATION PROCEDURE for SPITFIRE Model 0662 S12
Set Autostart Jumpers to CLOSED on the drive
The drive is connected to the external SCSI bus as the last device
and addressed as target 1 and an external power supply used.
1. After system boot-up, login as root and type the following commands
in a hpterm window:
"mediainit/dev/rdsk/c201dls0"
(This command takes some time to complete)
SCSI target 7 has the highest priority with the internal drive set
to target 6.
If the drive is set to a target address other than 1, then a different device file (i.e., not c201dls0) must be used:
e.g. "c201d2s0" for target 2
"c201d3s0" for target 3
Page 6
0662-001.txt
etc........
2. "/etc/mkfs-L/dev/rdsk/c201dls0 1027515 108 5 8192 1024 16 10 90 2048"
The syntax for the mfks command is:
"-L" - allows filenames up to 255 bytes in length
1027515 - number of DEV_BSIZE blocks in the filesystem
(DEV_BSIZE is defined in sys/param.h and is normally
1024)
108 - sectors per track
5 - tracks per cylinder
8192 - block size
1024 - fragmentation size (the minimum size a file is
allocated)
16 - number of cylinders per cylinder group
10 - minimum percentage of free disk space allowed
90 - revolutions per second
2048 - number of data bytes per inode slot
3. "fsck-p/dev/rdsk/c201dls0"
(to check the newly created filesystem)
4. "mkdir/spitfire" (Mount point)
5. "mount/dev/dsk/c201dls0/spitfire"
6. To mount the drive automatically on boot edit/etc/checklist to
include
"/dev/dsk/c201dls0/spitfire hfs rw, suid 0 1"
(you may need to use "chmod+w/etc/checklist" to get write permission
on the file).
This concludes the installation of the drive.
------------| SCSI PARITY |
------------Some older SCSI-1 systems may require disabling SCSI parity for
attachment. This is also a jumper selectable option.
