Installation Instructions
=-=-=-=-=-=-=-=-=-=-=-=-=-=

If you are performing a first time Windows 95 installation, see Installing 
the Driver When Installing Windows 95, below.  If Windows 95 is already
installed on your system, see Installing the Driver When Windows 95 is
Already Installed.

(NOTE:  When Windows 95 starts, if a "New Hardware Found" dialog is 
displayed after installing your 7800 Family host adapter, please select 
"Driver from disk provided by hardware manufacturer".  Then insert your 
Adaptec 7800 Family Manager Set v3.00 Diskette and type a:\win95 as the
path; follow the succeeding on-screen instructions.)


Installing the Driver When Installing Windows 95
----------------------------------------------------------------------

For non-ultra2 host adapters a version of the aic78xx.mpd driver is embedded
(included) in the Windows 95 installation CD-ROM.  
During a normal Windows 95 installation, the 7800 Family UltraSCSI or
earlier host adapter is detected in your system and the embedded 
aic78xx.mpd driver is automatically installed.  Once the Windows 95 
installation is complete, you can update the aic78xx.mpd driver with the 
most recent version of the driver by following the instructions in 
Installing the Driver When Windows 95 is Already Installed, below.

(NOTE:  If Windows 95 installation cannot detect the 7800 Family UltraSCSI
or earlier host adapter installed in your computer, you must install the 
aic78xx.mpd driver manually once Windows 95 installation is complete.  To 
determine if the aic78xx.mpd driver was installed, and to install the driver 
manually, see Installing the Driver When Windows 95 is Already Installed,
below.)


Installing the Driver When Windows 95 is Already Installed
------------------------------------------------------------------------------

To update or install the aic78xx.mpd or aic78u2.mpd 
driver if Windows 95 is already installed, follow these instructions:

(NOTE:  All Adaptec non-ultra2 7800 Family host adapters use the 
same aic78xx.mpd driver.  Only Ultra2 host adapters use the 
aic78u2.mpd driver.  Once the driver is updated, 
it is not necessary to update it again for each 7800 Family host 
adapter installed in your system.)


    1 Start Windows 95.

    2 Click the Start button on the Windows 95 task bar, and then
      point to Settings.

    3 Click Control Panel.
    
    4 Double-click the System icon.
    
    5 On the Device Manager tab, click the plus sign next to the SCSI
      controller icon.
    
    (NOTE:  If Windows 95 cannot determine the type of host adapter
    installed in your computer, a yellow question mark labeled Other
    devices appears instead of the SCSI controller icon.  To continue, 
    click the plus sign next to the question mark; a yellow question
    mark labelled PCI SCSI Bus Controller then appears.)
    
    6 Double-click the 7800 Family host adapter you wish to update,
      or if a yellow question mark labelled PCI SCSI Bus Controller
      is displayed, double-click the question mark.
    
    7 Insert the Adaptec 7800 Family Manager Set v3.00 Diskette into drive A:.
      
    8 Select the Driver tab.
    
    (NOTE:  If the version of Windows 95 you are using now displays a 
    window with a Update Driver button instead of a Change Driver button, 
    the remainder of your install procedure is covered in Updating the 
    Driver for Windows 95, Version OSR 2, described below.)
    
    9 Click Change Driver.  You may be asked to select the hardware type;
      if so, select SCSI Controllers.
     
   10 Click the Have Disk button and enter a:\win95 as the path.
      
   11 Click OK.
    
   12 Select the Adaptec 7800 Family host adapter, and click OK.
   
   13 Again, click OK.  The driver is now installed.
   
   14 You must restart your computer for the changes to take effect.  Click 
      Yes to restart your computer.  Click No to return to the system 
      properties window.


Updating the Driver for Windows 95, Version OSR 2
----------------------------------------------------------------------------

This section covers the remaining steps to updating the driver on
Windows 95, version OSR 2.

(NOTE:  If you have not already done so, follow the instructions in
Installing the Driver When Windows 95 is Already Installed, above.)

    1 Click Update Driver.
    
    2 Insert the Adaptec 7800 Family Manager Set v3.00 diskette into driver 
      A:.
    
    3 In the Update Device Driver Wizard, select Yes, and click Next.
    
    4 Select Other locations.
    
    5 Under the Location edit box, type a:\win95, then click OK.
    
    6 Click the Finish button.
    
    7 At the message "Please insert the disk labeled '7800 Family Manager 
      Set v3.00 Installation Disk'."  Insert the Adaptec 7800 Family 
      Manager Set v3.00 diskette and click OK.
    
    8 Another dialog box, Copying Files, appears with the message "The file
      'AIC78XX.MPD' or 'AIC78U2.MPD' on 7800 Family Manager Set v3.00 
      Installation Disk could not be found ...".  Type a:\win95 in the Copy Files
      from the edit box and click OK.  The driver is now installed.
    
    9 You must restart your computer for the changes to take effect.  Click 
      Yes to restart your computer.  Click No to return to the system 
      properties window.

    (NOTE: If you attempt to re-update the driver again, at step 3 above
    you will need to select No, click Next, and follow the on-screen
    instructions to re-update.)

Known Issues
=-=-=-=-=-=-=

    o In some cases, each channel of a MultiChannel adapter must be 
      updated/installed manually with the aic78xx.mpd driver on a 
      freshly installed Windows 95 system. Please follow the
      instructions listed under Installing the Driver When Windows 95
      is Already Installed for each channel.

    o Real mode ASPI drivers from EZ-SCSI are not needed, because
      Windows 95 miniport drivers support most SCSI host adapters and
      SCSI devices.  However, you will need to load the ASPI drivers 
      (including mscdex, if you have CD-ROM drive) if any of the following
      are true: 
      
      o You are running in MS-DOS mode and need to access your CD-ROM 
        drive.
      
      o You are using a scanner or another SCSI device with config.sys
        or autoexec.bat based drivers, such as HP's sjiix.sys.
        
      o You have an older model SCSI-1 CD-ROM driver that Windows 95 does 
        not support.
      
      o You are using a CD-Recorder drive (however, some newer models of
        CD-Recorder drives can use the embedded Windows drivers).
        
    o Some older models of SCSI CD-ROM drives are not compatible with the 
      embedded Windows 95 CD-ROM driver.  You can add support for the 
      CD-ROM drive by doing the following:
      
      1 Make sure your ASPI real mode drivers (including aspi8dos.sys, 
        aspicd.sys and mscdex.exe) are loaded and running from your 
        config.sys and autoexec.bat files.  Consult your EZ-SCSI 
        installation guide for more details.
      
      2 If step 1 did not work, find the file named cdtsd.vxd in the 
        \windows\system\iosubsys directory and rename it to cdtsd.sav.
        
    o The mapping between mscdex, which runs in real mode, and the
      Windows 95 CD-ROM driver does not match.  You can correct this in
      one of two ways:
      
      1 Comment out the line that loads mscdex.exe in the autoexec.bat 
        file.
      
      2 Change the /L switch on the line that loads mscdex.exe in the
        autoexec.bat file so it assigns the CD-ROM drive the next highest 
        logical drive letter after the hard disk drives.

    o Windows 95 does not support sharing of system interrupts (also
      known as IRQ's) between two or more I/O subsystem devices (i.e.
      network interface cards or hard disk adapters such as SCSI host
      adapters). When IRQ's are shared between I/O devices, lockups can
      occur while booting. If lockups occur, try moving or removing one
      or more PCI cards from one slot to another and bootup your computer
      again.  If problems continue, refer to your system documentation
      and/or your system technical support for information on adding
      your system configuration. (#12439, #12368, #12042)

    o The Family Manager Set v3.00 does not automatically update the
      embedded driver in Windows 95. After installing the driver for
      the AHA-2940U2W, there may be a conflict in the Device Manager
      with an existing or newly-installed Adaptec UltraSCSI or earlier 
      host adapter. To resolve this problem, simply update the embedded
      SCSI driver with the Family Manager Set v3.00 driver from the
      Device Manager.  (#12558)
