IBM SCSI-2 Fast PCI Bus Adapter Description

The IBM SCSI-2 Fast PCI Bus Adapter enables to use Small Computer Interface (SCSI) devices with computers that use the Peripheral Component Interconnect (PCI) bus.
The adapter meets the SCSI-2 standard set by the American National Standard Institute (ANSI), supports data transfer rates up to 10MB / sec. PCI offers local-bus type performance as well as industry standard connections for various peripheral devices. The adapter has both an internal and an external connector.

Selecting SCSI Cables

Internal Cable: A 50-Pin, flat-ribbon cable is required
External Cable: A Small SCSI-2 high-density 50-Pin Cable-connector.

Maximum Cable Length: Total length of all cables (internal & external) can be up to 6 meters (19.7 feet). If there are connected one or more Fast SCSI devices to the adapter external connector, then the maximum cable length is limited to 3 meters (appr. 9.8 feet).

Assigning SCSI IDs

Devices with higher SCSI IDs (ID-6) get priority over lower ones (ID-0).
Assign higher IDs to the most often used and fastest devices (ID-6 Hard Disk ID-3 CD-ROM).

Device Termination

When multiple devices are installed both internally and externally, active terminators are required on both ends of the bus for reliable operation at SCSI-2 Fast rates.

Updating the Computer Configuration

Depending on the computer model, you might have to change the PCI configuration information in the computer configuration programs.
For example, you might have to select the PCI expansion slot, enable the device (PCI adapter), enable bus mastering, select an interrupt request (IRQ) line, or change an I/O address value. Or you might have to change the setting of another feature to not conflict with the SCSI-2 Fast PCI Bus Adapter.

 Installing Support Programs 
 NOTE: For standard DOS/Windows 3.1 SCSI hard disk support, no
        device drivers are required
, the SCSI-2 Fast PCI adapter
        BIOS provides SCSI hard disk support automatically.  The
        DOS/Windows 3.1 ASPI manager driver is only required to
        be installed if devices other than hard disks are being
        attached to the SCSI-2 adapter and ASPI device specific
        drivers have been supplied with those devices or have
        been obtained from another source.
 Installing DOS/Windows 3.1 ASPI Manager and CD-ROM Support 
        Use the instructions in this section if you have non hard disk
        SCSI devices to install which have ASPI compliant device drivers.
        1. Turn on the display and system unit.  Wait for the DOS prompt.
        2. Insert the IBM SCSI-2 Fast PCI Bus Adapter Device Drivers
           Diskette which contains the IBMASPCI.SYS driver and other
           files required for DOS/Windows support into the diskette drive.
        3. Type the following:
                  copy a:\IBMASPCI.SYS c:\
           and then press Enter.
           To include support for IBM CD-ROM drives, also type the following:
                  copy a:\IBMPCICD.SYS c:\
           and then press Enter.
                  copy a:\MSCDEX.EXE c:\
           and then press Enter.
        4. Edit the DOS CONFIG.SYS file to add the following statement.
           NOTE: A /Q parameter may be added to the end of this device=
                 statement to suppress the display of messages while
                 the driver is scanning for SCSI adapters and devices.
           To include support for IBM CD-ROM drives, also add the following
           statement after the device=c:\IBMASPCI.SYS statement.
        5. To include support for the CD-ROM file system, edit the DOS
           AUTOEXEC.BAT  file to add the following statement.
                 MSCDEX /D:MSCD001 /M:10
           NOTE: It is recommended that the version of MSCDEX.EXE shipped
                 on this diskette be used with this adapter.
        6. Shutdown and then restart the system to activate the driver(s).
 Installing Device Drivers for Novell NetWare Versions 3.1X or 4.X 
        Use the instructions in this section if you have Novell NetWare
        Version 3.1X or 4.X installed.
   The NetWare driver (IBMPSCSI.DSK) supports disks, CD-ROM drives, and the
   NetWare SBackup utility for tape backup support directly; therefore,
   TAPEDAI.DSK and CDNASPI.DSK should NOT be loaded.  The driver does support
   an ASPI interface via the IBMASPI.NLM or IBMENTRY.NLM which has been tested
   with the following vendor tape backup software. The phone number for
   further information on each vendor product is provided below.
               Palindrome** - Network Archivist** (708-505-3300)
               Cheyenne**   - ARCserv**           (516-484-5110)
   NOTE: Tape drives which do not support 4K block sizes will result in a
         warning message that they must use ASPI tape backup software.
        1. Turn on the display and system unit.
        2. Prepare the NetWare startup drive according to the instructions
           in the NetWare manual.
        3. Insert the IBM SCSI-2 Fast PCI Bus Adapter Device Drivers
           Diskette which contains the IBMPSCSI.DSK driver and other
           files required for Netware support into the diskette drive.
        4. Type the following:
                  copy a:\IBMPSCSI.DSK d:
           (where d: is the NetWare startup drive) and press Enter.
           The IBMPSCSI.DSK driver is the base device driver for the
           IBM SCSI-2 FAST PCI Bus Adapter which supports hard disks,
           IBM CD-ROM drives, IBM tape drives, and IBM Rewriteable Optical
           Disk drives.  Additional Netware Loadable Modules (NLMs)
           described below are also provided to support Netware ASPI
           compliant device drivers required by SCSI device drivers
           and Netware compatible server backup software packages.
        5. Type the following:
                  copy a:\IBMASPI.NLM d:
           (where d: is the NetWare startup drive) and press Enter.
           The IBMASPI.NLM exports the "ASPI_Entry" entry point and sends
           IOCTL commands to the IBMPSCSI.DSK module. These two modules
           are usually all that is required for both disk and ASPI support.

           that the customer has successfully installed the IBMPSCSI.DSK,
           IBMASPI.NLM, IBM PCI SCSI adapter and devices. Successful
           execution of this NLM will result in a screen display showing
           all attached SCSI devices and their IDs. It is recommended that
           this NLM be run prior to installing tape backup software.
        7. Type the following:
                  copy a:\IBMENTRY.NLM d:
           (where d: is the NetWare startup drive) and press Enter.
           Use of the IBMENTRY.NLM file is optional and is provided for
           systems which already have another vendor's SCSI adapter
           configured to use the exported "ASPI_Entry" entry point. The
           export name of "IBM_Entry" is provided to ASPI device drivers as
           an alternate entry point in this situation.
        8a. If you are using Netware version 3.12, the following system
            patches also must be copied.
           Type the following:

           command prompt:
           and press Enter.
       11. At this time, make sure all activity on the server has stopped.
           Then load the DAICCFIX.NLM and REALMFIX.NLM NetWare patch files
           in that order if they were copied in step 8a or 8b above and
           you are using Netware version 3.12 or 4.xx.
           NOTE: The PM312.NLM or PM401.NLM patch files will be loaded
       12. At the NetWare server console prompt, type the following:
                  LOAD d:IBMPSCSI
           (where d: is the NetWare startup drive) and press Enter.
            This loads the basic device driver required for Netware
            support.  The appropriate NLMs that you chose to copy above
            should also be loaded at this time depending on your version
            of Netware and other installed equipment/software.
    In summary a customer should first load IBMPSCSI.DSK then IBMASPI.NLM. 
    Finally it is recommended that a customer load SCSISCAN.NLM which will
    do an SCSI scan of the bus using the ASPI interface to verify that
    the SCSI adapter, SCSI devices, NLM and DSK are loaded and operating
    properly. Any problems up to this point should be directed to IBM
    customer support.
    NOTE: Before creating or deleting NetWare disk partitions with the
          NetWare INSTALL.NLM utility while running NetWare 3.12 or 4.xx,
          the IBMASPI.NLM and/or IBMENTRY.NLM must be unloaded.
