Normally, a new kernel is tested before it is installed for general use. This test
usually takes the form of booting the new kernel while keeping a backup copy
of the old kernel. The following steps copy your kernel into the root file system
and reboot the system:
1. Login as the super-user (via login(1) or su(1) ), and change the correct
directory, if necessary.
# cd /usr/sys/ [
system-name
].
2. Copy your kernel to the root directory.
# cp bvmunix /testvmunix
3. Start single-user mode.
# /etc/single
4. Flush the in core buffer information out to disk.
# sync
5. Reboot the machine.
# reboot -q
6. When the reboot -q command finishes, the system will be under the
control of the PROM Monitor. Boot the new kernel.

Example
This example illustrates the generation of a kernel with one OEM supplied
device driver. We assume the following:
a.
We are configuring for the IRIS 1400 Workstation.
b. We have chosen OEM for our system name. This name is very important
because it binds the configuration process together.
c.
Existence of a mythical disk controller, the Wahoo 727. This device
is addressed at Multibus I/O address 0xFEDC (in the OEM range 0xF000 to
0xFFFF ). The interrupt level of this controller must be level 5.
This device is an smd disk controller which drives at most 4 disks in a standard
smd manner. We will give the device the name wa . This name is used in /dev for the
device nodes, and by config(8) for auto configuring and diagnostic purposes.
Based on this information, the necessary specifications for the configuration
file are:
