Before Installing Software Drivers: The following Troubleshooting Tips are
very important and must be read before installing the CI-2020M/G.

%%% Troubleshootings: %%%%%%%
 1. If your motherboard supports Plug-and-Play features, it will choose an IRQ
    number for its PCI cards. If the IRQ number is the same as CI-2020M/G jumper
    setting (default is IRQ11), the CI-2020M/G will not function properly. To
    solve this problem, you must run the motherboard CMOS setup utility, select
    "PCI AND PNP SETUP"' menu, specify the IRQ number (IRQ11 by CI-2020M/G
    default) to "ISA/Legancy" or "Used by ISA". Save and reboot your system to
    take effect. This is very important because it will prevent the motherboard
    from using the IRQ number which already used by the CI-2020M/G.

 2. If your boot disk is not connected to CI-2020M/G, and SCSI ID0, ID1 do
    not have any devices, please disable the CI-2020M/G SCSI BIOS to prevent
    the system from waiting too long for boot. To disable the ROM BIOS, just
    remove the jumper block of the BIOS selector (located at "DC00" by default).


A. Terminator:
   If your CI-2020M/G have both Internal SCSI devices and External SCSI devices
   connected to it, please remove the CI-2020M/G's terminator resistors(
   RT1, RT2, RT3). This is because some SCSI devices are noise sensitive if
   the terminators are not correctly disabled (or enabled).

B. The SCSI Device ID number:
   Basically, the CI-2020M/G is set at ID7, and its conventions are as follows:
   ID0 : SCSI Hard Disk Drive
   ID1 : SCSI Hard Disk Drive
   ID2 - ID6 : Non-Hard-Disk Devices (MO, CD-ROM, Jazz, ZIP, Tape, ...)
   ID7 : CI-2020M/G

   Note: The CI-2020M/G ROM BIOS only scans ID0 and ID1 to support the hard disk
         drives. However, more than 2 hard drives can be installed on CI-2020M/G.
         The extra drives need to be supported after the installation of
         the GSUNIDSK.SYS (and GSASPI.SYS) in your CONFIG.SYS.

C. Some sound cards use 340-35F I/O addresses which conflicts with the
   CI-2020M/G for their CD-ROM Port, this will cause the CI-2020M/G to be
   unable to detect SCSI devices, please change the I/O port of the sound card
   before doing the CI-2020M/G installation.

D. If some external SCSI devices can not work with the CI-2020M/G, you need to
   disable the Sync negotiation feature (by Closing the "ESN" jumper block on the
   CI-2020M, or specify the "Normal" mode in the CI-2020G configuration utility
   of CI-2020G), or you can add a "/ASYN" option following the command of
   GSASPI.SYS in your CONFIG.SYS:

        DEVICE = C:\GM82C700\GSASPI.SYS /ASYN

E. For MO (Magnetic Opticals) devices, if under DOS, you need to add in 2
   commands in your CONFIG.SYS (by typing them with a text editor, or
   running the SETUP program of CI-2020M/G utility disk):

       DEVICE = C:\GM82C700\GSASPI.SYS
       DEVICE = C:\GM82C700\GSUNIDSK.SYS

   - Use the GSFMT to format your BLANK MO media.
   - Before Running the GSFMT, please make sure the media is correctly
     inserted in the MO drive, otherwise, it might be rejected by the
     GSFMT program.

INSTALLING DOS/WINDOWS DRIVERS
****************************************************************************
F. Installing The CI-2020M/G Software Drivers:
   At the DOS prompt, type SETUP

   A:\>SETUP

   After proceeding with Setup, the following command lines are added
   into your CONFIG.SYS file:

      REM 04/30/96
      DEVICE=C:\GM82C700\GSASPI.SYS
      DEVICE=C:\GM82C700\GSUNIDSK.SYS
      DEVICE=C:\GM82C700\GSCDROM.SYS /D:MSCD000

   And the following command lines are added into your AUTOEXEC.BAT to support
   CD-ROM devices:

      REM 04/30/96
      C:MSCDEX /D:MSCD000

G. Reboot your system and it will run the new CONFIG.SYS and AUTOEXEC.BAT to
   make the CI-2020M/G function properly. If errors are reported while rebooting,
   then please check your jumper settings (or Configuration utility of CI-2020G)
   , most errors are caused by the mis-match of IR1,IR0, and IRQ jumper settings,
   please make sure that they are matched per the following table (CI-2020M):

   Interrupt Level   IR1    IR0     IRQ9    IRQ10    IRQ11    IR12
   ========================================================================
        IRQ9         CLOSED CLOSED  CLOSED  OPEN     OPEN     OPEN
        IRQ10        CLOSED OPEN    OPEN    CLOSED   OPEN     OPEN
        IRQ11        OPEN   CLOSED  OPEN    OPEN     CLOSED   OPEN
        IRQ12        OPEN   OPEN    OPEN    OPEN     OPEN     CLOSED

H. The GSASPI.SYS options:
   The GSASPI.SYS provides some options to RE-SET the jumper settings, when
   these options are set, it will overwrite the jumper settings as follows:

   /D       : Display the CI-2020M/G current hardware settings on the screen
   /ASYN    : Disable SCSI bus Sync Negotiation options, overwrite ESN jumper
   /HAID:n  : n = Host Adapter ID, valid values are 0, 1, 2, 3, 4, 5, 6, 7
   /IRQ:n   : n = IRQ channel, valid values are 9, 10, 11, and 12, please
              note that this settings still need to match the IRQ selector
              jumper (IRQ9,IRQ10,IRQ11,IRQ12) to make it function properly .
   /NPAR    : Disable the SCSI parity check function because some SCSI device
              do NOT support parity checking

   example:
             DEVICE=C:\GM82C700\GSASPI.SYS /D /ASYN /NPAR /IRQ:10

   IMPORTANT:
   Please Note that if the CI-2020M/G ROM BIOS is NOT installed ( for some
   simple solutions which do NOT need the ROM BIOS to boot from the SCSI Hard
   Disk), the above option is the only way to tell the GSASPI.SYS its
   correct hardware settings, for example, IRQ number (because the jumper
   settings are no longer valid for the GSASPI.SYS if no ROM BIOS are read and
   passed to the adapter to it).

I. Installing the CI-2020M/G for Windows 95:
   Windows 95 supports CI-2020M/G directly with its built-in driver, so
   no extra drivers or diskette are supplied with the CI-2020M/G. The
   recommanded installation is as follows:

Installing CI-2020M/G if Windows 95 is NOT installed yet! (New System)
****************************************************************************
In this case, Windows 95 will scan the SCSI controllers automatically,
and find a compatible SCSI driver to support the CI-2020M/G directly.
procedure recommanded by the Windows 95 installation program.

Installing CI-2020M/G if Windows 95 is already installed.
****************************************************************************
During the following installation procedure, no special driver diskette is
needed because your CI-2020M/G uses drivers that are already supplied with
Windows 95.

1.  Windows 95 must be installed on the system prior to installing the
    driver.

2.  Close any running applications.

3.  Open "My Computer".

4.  Double click on the "Control Panel" icon.

5.  Double click on the "Add New Hardware" applet.

6.  Click on the "Next" button.

7.  There is a window to ask you "Do you want Windows to search for your new
    hardware?", choose "No" then click on the "Next" button.

8.  There is a Window listing hardware types, select "SCSI controllers"
    then click on the "Next" button.

9.  There is a Window listing many SCSI controllers avaliable in Windows 95,
    Choose "Adaptec AHA-152X / AHA-1510 SCSI Host Adapter", then click on
    the "Next" button.

10. If there is a window showing the settings (resources) to be used by the
    driver, then click on the "Next" button again. At this point, the system
    will install the driver. (The resources may not be the same as your
    CI-2020M/G default settings, don't worry about that, you can change the
    resources of Windows 95 later on).

11. Click on the "Finish" button.

12. Then the system will ask you to restart the system. If the settings
    reported in step 10 are not those set on the host adapter, you must
    adjust the settings by using the device manager in the System control
    panel before restarting your computer.

13. If you have more than one CI-2020M/G host adapter installed in your
    system, you should run the setup procedure several times.

Un-Installing the Driver:
****************************************************************************
You can use the device manager in the System control panel to remove the
driver.

J. Windows NT3.5X, 4.0 Installation:
   The CI-2020M/G does NOT need additional driver(s) to support Windows NT.
   During the installation; the CI-2020M/G will be scanned and will
   automatically find a suitable driver.

K. OS/2 V2.X, WARP
   OS/2 also supports the CI-2020M/G directly. When installing OS/2,
   the installation program will hook on the correct driver for CI-2020M/G,
   and then complete the installation as it recommands in the OS/2 manual.

L. Novell Netware V4.x
   For Novell V4.x, Please choose "Adaptec AHA-152X" when Netware prompts you
   to load the SCSI Driver. Please Note that AHA-1522 is a trademark of
   Adaptec, Inc. The CI-2020M/G is emulates the Adaptec AHA-152X registers so
   that the driver supplied with Netware works fine with both AHA-152X and
   the CI-2020M/G, after loading the driver, please complete Netware
   installations.

M. SCO UNIX V3.2.4 or later version:
   SCO UNIX directly supports CI-2020M/G, when completing installation, the
   SCO UNIX installation program will scan the CI-2020M/G and find a suitable
   driver in its kernal to support it.
