- AHA-1540/42B INSTALLATION GUIDE
-
-
- HARDWARE INSTALLATION
-
- The Adaptec AHA-154XB 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-154XB is shipped with the following settings:
-
- SCSI Address 7
- SCSI Parity Enabled
- Terminators Installed
- Terminator Power Supplying
- Synchronous Negot. Disabled
- DMA Channel 5
- Interrupt Channel 11
- AT Port Address 330h
- AT Bios Address DC000H, Enabled
- Bios Wait State 0, Disabled
- FD Controller Enabled (AHA-1542B)
- DMA Transfer Speed 5 MB/second
- Auto Sense Enable
-
- TO PERFORM INSTALLATION:
-
- TURN OFF POWER TO THE SYSTEM AND EXTERNAL EQUIPMENT.
-
- Remove the cover of your AT personal computer to expose 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 edge connectors, one 62-pin and the
- other 36 pin.
-
- Remove the corresponding system expansion slot cover by turning the screw
- that secures it from the top counter-clockwise.
-
- Align the AT I/O Bus Connector on the bottom of the AHA-154X into this AT
- slot. Use the screw from the corresponding expansion slot cover to secure
- the AHA-154X's bracket to your AT system frame.
-
- 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 terminators
- removed.
-
- The SCSI factory-installed Bus terminators on the AHA-154X should be removed
- if and only if you attach SCSI devices to both an internal and external cable
- since the internal and external cable SCSI connectors are the same SCSI Bus.
-
- Attach the SCSI Bus to the host adapter and the peripherals, using either
- the internal or external connector, making sure that pin 1 orientation is
- maintained throughout the bus.
-
- If the host adapter is not the first or the last unit on 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 configure 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 settings.

- SOFTWARE INSTALLLATION
-
- Copy the files from the ASW-1410 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 CONFIG.SYS file must
- contain the following DEVICE=commands:
-
- DEVICE = ASPI4DOS.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 = ASPI4DOS.SYS (/D) (/P<port address) (/L) (/V) (/W) (/X<speed>)
- (/N<bus on time>) (/F<bus off time>) (/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
- F1 key. The AFDISK may be exited at any time without executing by pressing
- the ESC key and being careful to choose the selections that do not write to
- or format the disk.
-
- 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 partition(s).
-
-
- TERMINATION
-
- The SCSI bus must 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 terminators removed. The AHA-
- 154XB host adapter is usually the first device on the SCSI Bus and has
- terminators installed at the factory.
