Using SCO UnixWare and the Host Adapter
This section contains useful information on using SCO UnixWare
and your host adapter.
Using Tunable Parameters
For SCO UnixWare, some parameters are defined in the following
files:
/etc/conf/pack.d/adsl/space.c
These parameters can be tuned for the
adsl20 / adsl or adsb20 / adsb
drivers. Please refer to the comments in the appropriate
space.c file
for a description of these parameters. After modifying the
space.c
file, you must rebuild the kernel then reboot the system for the new
parameters to take effect. To rebuild the kernel, type the following,
and press Enter after each line:
/etc/conf/bin/idbuild -B
cp /etc/conf/cf.d/unix /stand/unix
Note:
The drivers support tagged queuing and
reinitialization.
Using Multiple Host Adapters
When using multiple host adapters, consider the following:
■
The host adapter and computer must be configured for
multiple host adapters as explained in the host adapter’s User’s
Guide.
■
To boot from the 7800 Family host adapter, make sure the host
adapter is installed in the lowest PCI slot number. See your
host adapter’s User’s Guide.
■
SCO UnixWare 2.x supports auto-configuration. When adding
multiple host adapters to an existing SCO UnixWare 2.x
system, simply install the board and reboot; the system
automatically reconfigures and rebuilds the kernel. If you want
to choose a host adapter to boot from, simply disable the BIOS
on all other host adapters.
