Installing Windows NT 3.51 and the Driver
This section describes how to install the aic78xx.sys
driver at the same time you install Windows NT 3.51. If
Windows NT 3.51 is already installed and you wish to
install or update the aic78xx.sys driver, see “Using Win-
dows NT to Install or Update the Driver,” found later in
this section.
Performing a Windows NT 3.51 Installation
Follow these instructions only if you are installing
Windows NT 3.51 for the first time. You can install
Windows NT 3.51 from a diskette drive or from a
CD-ROM drive; whichever you choose, make sure the
hardware installation is completed prior to following
these steps.
NOTE: An older version of the aic78xx.sys driver is
included in the Windows NT installation diskettes (or on
the CD-ROM). To avoid loading the older driver during
Windows NT installation, use the following procedure to
install the new driver included on the driver diskette you
create from the Dell Server Assistant CD.
1. If you choose to install Windows NT from a dis-
kette drive, locate the Windows NT Disk 1 for
Floppy Installation diskette. Make a backup copy
of this diskette.
If you are installing from a CD-ROM drive, locate
the Windows NT Setup Disk 1 for CD-ROM Installa-
tion diskette. Make a backup copy of this diskette.
2. Put the backup diskette into drive A, and turn on
your system. When prompted, insert the Windows
NT Setup Disk 2 diskette.
3. From the Welcome to Setup screen, press
<Enter> to set up Windows NT.
4. When prompted for the setup method, select
Custom.
5. Press <Enter> to continue.
Insert the Windows NT Setup Disk 3 diskette when
prompted to do so.
6. After a period of time, Windows NT Setup
displays all recognized SCSI controllers. If no
SCSI controllers are found, Windows NT Setup
displays none. Type to configure additional
SCSI controllers.
7. Expand the list of additional SCSI controllers,
select Other, and press <Enter>.
The Other option is at the end of a long list of SCSI
controllers and is highlighted.
8. Insert into drive A the Windows NT 3.51 driver
diskette you created, enter the following path to
the installation files, and then click OK.
a:\scsi
9. The screen displays the adapter drivers sup-
ported on the diskette. The Adaptec
AHA-2940UW/AIC-78xx (PCI) NT 3.51 driver is
highlighted by default; press <Enter> to select
this driver.
10. If you want to add other SCSI controllers (not
part of the Adaptec 78xx series), do so at this time
by repeating steps 7 though 9 for each additional
adapter, inserting the appropriate diskette
provided by the hardware manufacturer. Because
all Adaptec 78xx series SCSI controllers use the
same driver, you configure all Adaptec SCSI con-
trollers at the same time.
11. Press <Enter> to continue with the Windows NT
operating system setup. Follow the instructions
on the screen and in the Windows NT installation
documentation.
Performing a Windows NT 4.0 Installation
The Windows NT 4.0 operating system has SCSI drivers
for the Adaptec 78xx series of SCSI controllers integrated
into the operating system. When you load the operating
system software, the drivers are automatically loaded.
Using Windows NT to Install or Update the Driver
This section describes how to install or update the
aic78xx.sys driver if Windows NT 3.51 is already
installed. If you are installing Windows NT 3.51 for the
first time, see “Installing Windows NT 3.51 and the
Driver” found earlier in this section.
