Bit Mask Options

Use this example to aid in calculating bit-mask option
hex values. Each SCSI device (ID 0-7 or 0-15 for the
AIC-7880, AIC-7860, and optional AHA-2940W) is
enabled by a 1 in its corresponding bit position. As illus-
trated in Figure 3-1, dev_enable=05 enables driver
registration of the devices at SCSI IDs 0 and 2.

Sample load Command

The following command is a sample load command with
no option switches (loaded from drive A):
load a:\scsi\aic7870.dsk
Slot values that already have another registered device do
not appear on the screen. Only the slots available for use
by the host adapter appear when this command is entered.
If an error message appears as you attempt to load the
driver, refer to "Troubleshooting for NetWare" found
later in this section.
The following command is a sample command loading
the aic7870.dsk driver with command line options
(loaded from drive A):
load a:\scsi\aic7870.dsk verbose=y slot=22

Using startup.ncf and autoexec.ncf

The startup.ncf and autoexec.ncf files contain a set of
commands that are executed during the boot routine. The
startup.ncf file contains commands to load the disk driv-
ers. Once startup.ncf loads disk drivers, control is
passed to the autoexec.ncf file to complete the boot rou-
tine. For additional information on the startup.ncf and
autoexec.ncf files, refer to your NetWare documentation.

To automatically load the aic7870.dsk driver during the
boot routine, the startup.ncf file must contain a load
command line that specifies the location of the driver on
the hard-disk drive, any available options (see "Using the
load Command Line Options" found earlier in this sec-
tion), and the slot number (see "Calculating the Slot
Number" found earlier in this section).
NOTE: To load the driver from your hard-disk drive, the
aic7870.dsk driver and aspitran.dsk module must be
copied from your NetWare 3.12 or 4.11 SMP driver dis-
kette to a directory on your hard-disk drive (usually, the
server's start-up directory [for example, c:\nwserver]).
The syntax to load the aic7870.dsk driver is:
load [pathname] aic7870.dsk [options] slot=x
For example, the command line to load the driver from
the c:\nwserver directory with the verbose= option on
and a slot number of 16 follows:
load c:\nwserver\aic7870.dsk verbose=y
slot=16
NOTE: For each Adaptec 78xx host adapter installed, a
separate load command line must be included in the
startup.ncf file. The slot number (slot=) identifies the
specific adapter.
To modify the startup.ncf file, follow these steps:
1. Type install at the NetWare prompt, and press
<Enter>.
2. Select the appropriate menu choice that allows
you to edit the startup.ncf file.
3. Make the necessary changes. When you are fin-
ished, press <F10>.
