Dell 6100 - Calculating the Slot Number

Installing and Configuring SCSI Drivers 3-11
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.)
7. When the following message appears on the
screen, press <Enter> or <Esc> to exit the
EZ-SCSI utility:
(Adaptec EZ-SCSI has been successfully
installed…)
8. Remove the Adaptec EZ-SCSI diskette 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 will need to calculate the slot number to
include it as part of the load command line.
NOTE: The Novell NetWare operating system will auto-
matically calculate 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.
To calculate the slot number, you must first obtain the
bus:device xx:xxh values identified when running the
SCSISelect utility for your host adapter. This calculation
is done manually, as described in the following 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” 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. Because the PowerEdge 6100
system has peer PCI buses, and the built-in AIC-7880
host adapters are located on the second bus, the bus
value for these host adapters is usually 1.
The device variable refers to the physical slot num-
ber on the PCI bus. The device number is in hex; you
must convert it to a decimal number. The device
number for the SCSI A is 11; the device number for
the SCSI B is usually 12.
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, bus 0, device 6), the slot number is 22 (22 =
[0 * 100] + 6 + 16). The slot number for the built-in
AIC-7880 host adapter is 126 (126 = [1 * 100] + 10
+ 16).
