specify an explicit attachment of the device to the driver in question.
Most installations have no need to specify explicit device driver
specifications.
Explicit device driver bindings are specified in a system file as lines with
the following form:
driver deviceID drivername
The deviceID is the identification of the hardware device in question.
Devices are presently identified using hardware paths (see ioscan (1M)
for details), but this may change in future HP-UX releases. The
drivername is the name of the kernel module that is the desired driver
for the device.
The Kernel Configuration Log File
It is often useful to know what configuration changes have been made on
a system. For this purpose, the kernel configuration tools automatically
maintain a log file at /var/adm/kc.log. This file lists every change
made using the kernel configuration commands. (Some configuration
changes can be made by calling kernel system calls directly. These
changes are not logged. Changes made through kcweb, the web-based
interface for kernel configuration, are logged since kcweb uses the kernel
configuration commands to make the changes.)
The log file is a plain text file that you can view directly. The kclog
command is provided for when you want to do an intelligent search of the
log file, but its use is optional. (More information on the kclog command
can be found in the kclog (1M) manpage.)
All of the kernel configuration commands accept a -C (Comment) option
when they are being used to make configuration changes. The -C option
allows you to specify a comment that will be included in the log entry for
your change. This can help readers of the log understand the reasons for
your changes.
To add a comment to the log without making a configuration change, use
kclog -C.
In the kcweb tool, you can select the change log viewer menu item from
the navigation column to see the kernel configuration log file (in reverse
order).
