Installation Instructions

If you are performing a first time Windows 98 installation, see the 
"Installing the Driver When Installing Windows 98" section, below.  If 
Windows 98 is already installed on your system, see the "Updating the 
Driver for Windows 98" section.

Installing the Driver When Installing Windows 98

A fresh Windows 98 installation will attempt to detect all Adaptec 
SCSI host adapters in your system.  If it is unable to do so, follow 
the instructions in the "Updating the Driver for Windows 98" section 

(NOTE:  When Windows 98 starts, if "New Hardware Found" is displayed, 
select "Driver from disk provided by hardware manufacturer".  Insert 
your Adaptec 7800 Family Manager Set v3.02 diskette and type a:\win9x 
as the path; follow the on-screen instructions.)

Updating the Driver for Windows 98

To update or install the aic78xx.mpd or aic78u2.mpd driver if Windows 98 
is already installed, follow these instructions:

    1 Start Windows 98.

    2 Click the Start button on the Windows 98 task bar, and then
      point to Settings.

    3 Click Control Panel.
    4 Double-click the System icon.
    5 On the Device Manager tab.

    6 Click the plus sign next to the SCSI controller icon.
    (NOTE:  If Windows 98 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 labeled "PCI SCSI Bus Controller" then appears.)
    7 Double-click the 7800 Family host adapter you wish to update,
      or if a yellow question mark labeled "PCI SCSI Bus Controller"
      is displayed, double-click the question mark.    
    8 Select the Driver tab.
    9 Click Update Driver.
   10 Insert the Adaptec 7800 Family Manager Set diskette into drive

   11 In the Update Device Driver Wizard, click Next.

   12 Select the button for "Search for a better driver than the one 
      your device is using now. (Recommended)".  Click Next.

   13 Select "Specify a location".

   14 In the "Specify a location" edit box, type "a:\win9x", then 
      click Next.

   15 When Windows indicates "Location of driver: A:\win9x\aic78xx.inf",
      click Next.

   16 Windows will now copy the files for your host adapter.

   17 Click "Finish".

   18 You must restart your computer for the changes to take effect.

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 98 system. Please follow the
      instructions listed under Updating the Driver for Windows 98
      for each channel.

    o Real mode ASPI drivers from EZ-SCSI are not needed, because
      Windows 98 miniport drivers support most SCSI host adapters and
      SCSI devices.  However, you will need to load the ASPI drivers 
      (including MSCDEX.EXE, 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 
      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 98 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 98 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.EXE, which runs in real mode, and the
      Windows 98 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 
      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 98 does not support sharing of system interrupts (also
      known as IRQs) between two or more I/O subsystem devices (i.e.
      network interface cards or hard disk adapters such as SCSI host
      adapters). When IRQs 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.

    o When updating/installing the driver for a host adapter, the 
      Family Manager Set v3.02 will not automatically install both 
      Ultra2 and Ultra/Fast drivers.  If you require both drivers, 
      you will have to install them seperately, as per individual host 
      adapter.  For example, 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 driver 
      for the conflicting host adapter with the Family Manager Set 
      v3.02 driver from the Device Manager.
