Installation guide

remove_attrs file, you omit the subsystem name from the command line,
as shown:
# /sbin/sysconfigdb -r -f remove_attrs
5.3.8.6 Deleting Subsystem Entries from the Database
To delete the definition of a subsystem from the /etc/sysconfigtab
database enter the /sbin/sysconfigdb −d command.
For example, to delete the generic subsystem entry in the database, issue
the following command:
# /sbin/sysconfigdb -d generic
The generic subsystem receives its default values the next time it is
configured.
5.4 Static System Configuration
Static system configuration refers to the commands and files used to build
and boot a new kernel and its static subsystems. The subsystems are
viewed as static because they are linked directly into the kernel at build
time. The steps you take to build a statically linked kernel vary depending
upon why you want to modify the kernel.
If you modify the kernel to add a device driver, from Compaq or from a
company other than Compaq, you follow these general steps:
• Install the device driver.
• If necessary, edit the target configuration file.
In some cases, the device driver provides a Subset Control Program
(SCP) that executes during the installation procedure and registers the
driver in the necessary system configuration files. In this case, you need
not edit the target configuration file yourself.
If the device driver does not provide an SCP, you must edit the target
configuration file yourself.
• Build a new kernel.
If your device driver includes an SCP, build a new kernel by running
the /usr/sbin/doconfig program as described in Section 5.4.3. If you
need to edit the target configuration file before you build a new kernel,
refer to Section 5.4.1.
• Shut down and reboot your system.
If you modify the kernel to add support for certain kernel options, you can
build the new kernel by running the /usr/sbin/doconfig program and
