Installing and Configuring SCSI Drivers 3-9
4. When the first EZ-SCSI screen appears, read the
text carefully.
You can press <F1> on any screen for additional
help. Press <Esc> to exit a Help screen.
5. Press <Enter> to continue with the installation.
6. Follow the instructions that appear on the screen.
Press <Enter> at every screen to accept the
EZ-SCSI default values.
If you accept all the default values, the EZ-SCSI util-
ity copies the files from the diskette to the c:\scsi
directory. (The EZ-SCSI utility creates this directory
if the directory does not already exist.) The EZ-SCSI
utility also adds command lines to your computer’s
configuration files (autoexec.bat and/or config.sys)
that will load the required device drivers into mem-
ory when you boot your computer.
Press <Esc> to continue after the EZ-SCSI utility
enters changes to your system configuration files.
If you want to copy the files to a different directory
or control the changes to your configuration files,
follow the instructions on the screen. Press <F1> on
any screen to see more information.
NOTE: If the EZ-SCSI utility is unable to locate the
mscdex.exe file in the c:\dos directory, it will prompt
for a pathname to access this file. (Without this file,
the utility cannot access the computer’s CD-ROM
drive.)
When the message
(Adaptec EZ-SCSI has
been successfully installed…)
appears
on the screen, press <Enter> or <Esc> to exit the EZ-
SCSI utility, and remove the Adaptec EZ-SCSI dis-
kette from the drive. Then reboot your computer by
pressing <Ctrl><Alt><Del>.
Calculating the Slot Number
The slot number is used to uniquely identify each
Adaptec 78xx Family host adapter installed in your sys-
tem. To properly load the driver for each Adaptec 78xx
host adapter, you need to calculate the slot number and
include it as part of the load command line.
NOTE: The NetWare operating system automatically cal-
culates the slot number for you if you are installing only
one expansion card. If you are installing multiple
expansion cards, use the following procedure to calculate
the slot number.
In order to calculate the slot number, you must first
obtain the bus:device xx:xxh
values identified when run-
ning the SCSISelect utility for your host adapter. This
calculation is done manually, as described in the follow-
ing steps:
1. Make sure your system is properly set up and
configured.
2. Run the SCSISelect utility for your host adapter.
See “The SCSISelect Utility” found earlier in this
chapter for general instructions.
3. The first screen of the SCSISelect utility displays
the bus:device xx:xxh
numbers in the upper right-
hand corner. Write down these numbers exactly
as they appear.
The bus variable refers to the PCI bus on the system.
The default for bus is 0. Usually only one PCI bus is
supplied with a system; however, systems may con-
tain more than one PCI bus. The device variable
refers to the physical slot number on the PCI bus.
The device number is in hexadecimal; you must con-
vert it to a decimal number.
NOTE: The device slot number identified through
SCSISelect is not the same as the slot number needed
to load the driver through the load command line.
Use the following formula to calculate the slot
number:
slot number = (bus * 100) + device + 16
For example, if the bus:device number is 0:06h (that
is, 0:6), then the slot number is 22 (22 = [0 * 100] +
6 + 16).
Installing NetWare and the Driver
This subsection describes how to install the aic7870.dsk
driver at the same time you install NetWare 4.11. If Net-
Ware 4.11 is already installed and you wish to install or
update the aic7870.dsk driver, see “Using NetWare to
Install or Update the Driver” found later in this section.
