g. Save the old system ﬁle by moving it. Then move the new system ﬁle

into place.

mv /stand/system /stand/system.prev

mv /stand/build/system /stand/system

h. Prepare for rebooting by invoking the kmupdate command. This

action sets a ﬂag that tells the system to use the new kernel when it

restarts.

/usr/sbin/kmupdate

Step 2. Notify users that the system must be rebooted.

Step 3. Shut down and halt the system using the /usr/sbin/shutdown -h

command.

Step 4. Turn off power to the SPU.

Step 5. Install the peripheral device. Make sure the peripheral's hardware

address is set to the hardware path speciﬁed in the driver statement of

the /stand/system ﬁle.

Step 6. Power up the peripheral device and then the SPU.

When the kernel reboots, you can verify that the custom driver was

conﬁgured into the kernel by executing /usr/sbin/ioscan

-f. You should see the driver associated with its intended device at the

hardware path you speciﬁed in step 2.

For further information on driver statements and other custom-tailoring

of the /stand/system ﬁle, consult the conﬁg (1M) manpage. The config

program is used by mk_kernel when you build a kernel.

Under most circumstances, insf creates useful device special ﬁles when

the system boots up. However, for some special circumstances, it may be

necessary to create these ﬁles using mknod.
