Adaptec AHA-1520 User manual

SOFTWARE INSTALLATION
Copy the files from the ASW-1210 Program diskette to the
root directory of drive C using the MS-DOS COPY command.
In order for the ASPI MS-DOS Manager files to be loaded
whenever the system is booted, the CON FIG.SYS file must
contain the following DEVICE= commands:
DEVICE = ASPl2DOS.SYS
DEVICE = ASPIDISK.SYS
Using any ASCII file editor, add the individual device driver
commands to an existing CONFIG.SYS file, or follow the
instructions in the MS-DOS Operations Reference Manual to
create a new CONFIG.SYS file. FAILURE TO LOAD ALL THE
DEVICE DRIVERS IN THE CORRECT ORDER, CAUSES THE
PROGRAM TO NOT BE INSTALLED. The following command.
line options may be added to the device drivers in the
CONFIG.SYS file. (Refer to the User's Manual for details.)
DEVICE = ASPl2DOS.SYS (/DJ (/P<port address) (/L) (/VJ (/WJ
(/X<speed>) (/N<bus on time> l (/F<bus off time>l (/I).
MS-DOS provides access to physical hard disk drives C and
D. You must use the MS-DOS FDISK and Format programs for
drives C and D. DO NOT use AFDISK with drive C and D. To
use a hard disk partitioned by AFDISK as drive C or D, you
must use AFDISK to delete the partitions, and then use MS-
DOS FDISK to create new partitions.
When starting AFDISK program, it must be run from the root
directory of drive C or the AFDISK directory if an AFDISK
directory was created. When ready, type:
AFDISK (at the DOS prompt)
and press ENTER. The AFDISK utility is menu driven. Follow
the directions on the screen to partition and format the
selected SCSI devices. The AFDISK utility also includes an
on-line HELP file which is accessed by pressing the Fl key.
The AFDISK may be exited at any time without executing by
pressing the ESC key.
When the SCSI device(s) are successfully partitioned and
formatted, reboot the system. This saves any changes
made and allows use of the newly installed disk(s) or
partitions(s).

F.C.C. CERTIFICATION
This equipment generates and uses radio frequency. and if not inst.ailed and
usedproperly, that is. in strict accordance with the manufacturer'sinstructions.
may cause interference to radio and television reception. It has been type-
tested and found to comply with the limits for a Class B computing device in
accordance with the specificationsin 'SubpartJ of Part 15 of FCC Rules'. which
are designed to provide reasonable protection against such interference in a
residentialinstallation. However.there is no guarantee that interferencewill not
occur in a particular installation. If this equipment does cause interference to
radio or television reception. which can be determined by turning the equip-
ment off and on. the user is encouraged to try to correct the interference by
one or more of the following measures:
Reorient receiving antenna.
Relocate the computer with respect to the receiver.
Move the computer away from the receiver.
Plug the computer into a different outlet so that computer and
receiver are. on different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/
television technician for additional suggestions. The user may find the following
booklet prepared by the Federal Communications Commission helpful.

Installation Guide

HARDWARE INSTALLATION
The Adaptec AHA-152X AT-to-SCSI Host Adapter has
been designed to operate as shipped in the majority of
AT class computers. The host adapter's factory default
settings should remain in their original positions. The AHA-
l 52X is shipped with the following factory default settings:
SCSI Disconnection
SCSI Address
SCSI Parity
Terminators
Terminator Power
Synchronous Negot.
DMAChannel
Interrupt Channel
AT Port Address
AT BIOS Address

TURN OFF POWER TO THE SYSTEM AND EXTERNAL EQUIP-
MENT.
Remove the cover of your AT personal computer that
exposes the AT bus slots.
Locate an unused AT expansion slot in your AT system. AT
type slots can be recognized by the fact that they have
2 physical edge connectors, one 62-pin and the other
36-pin, in line with one another.
Remove the corresponding system expansion slot cover
by turning the screw that secures it from the top counter-
clockwise.
Align the AT 1/0 Bus Connector on the bottom of the
AHA-l52X into this AT slot. Use the screw frofTI the corre-
sponding expansion slot cover to secure the AHA-l 52X's
bracket to your AT system frame.
Attach the SCSI Bus to the host adapter and the periph-
erals, using either the internal or external connector,
making sure that pin l orientation is maintained through-
out the bus.
If the host adapter is not the first or the last unit in the
cable, remove the SCSI terminators from the board.
Reassemble the system in the reverse order.

Jumper Configuration Reference
Five sets of jumpers are located on the board to config-
ure user-selectable options. jumpers installed at the
factory are shown as "(x)." Those not installed are shown
as "o." It should not be necessary to change the jumper

DEFAULT SETTINGS AND REFERENCE DIAGRAM
Terminators
The SCSI bus must also be terminated correctly to
ensure proper operation. The first and last physical
SCSI devices on the SCSI cable must have terminators
installed. All other SCSI devices must have termina-
tors removed. The AHA-l52X host adapter is usually
the first device on the SCSI Bus and has terminators
installed at the factory.
