The MACHINE computers do not generally need any specific preparation.
|
|
|
|
You might want to check that the console ``path'' in the PDC firmware
|
|
points to the device you plan to use, and change it if necessary. Most
|
|
MACHINE machines will allow to select console path from the BOOT_ADMIN>
|
|
prompt. To reach this prompt, abort the autoboot process and if a menu
|
|
appears, enter ``a'' to select the "Boot Administration mode."
|
|
|
|
To select the first serial port as console, type:
|
|
|
|
BOOT_ADMIN> path console rs232_a.9600.8.none
|
|
|
|
or to select graphics as console:
|
|
|
|
BOOT_ADMIN> path console graphics
|
|
BOOT_ADMIN> path keyboard hil
|
|
or
|
|
BOOT_ADMIN> path console graphics
|
|
BOOT_ADMIN> path keyboard ps2
|
|
|
|
depending upon your keyboard type.
|
|
|
|
On a few models, such as the 9000/712, the PDC firmware will not allow
|
|
the console path to be changed. In this case, it is possible to change
|
|
it from the OpenBSD boot loader. After booting OpenBSD in interactive
|
|
mode (for example, if booting over the network, by entering ``boot lan
|
|
isl''), enter the following at the ``boot>'' prompt:
|
|
|
|
boot> machine console rs232.9600.8.none
|
|
|
|
dnl I hope I'll never write ``been there, done that'' here. Rest
|
|
dnl assured I have added a lot of safeguards in this console code
|
|
dnl to prevent people from rendering their 712s unusable.
|
|
dnl At least mine is still alive, and I have played a lot with its
|
|
dnl console path... -- miod
|
|
WARNING!
|
|
Make sure to type the console path correctly or the 9000/712 can
|
|
become unusable, and will require a special ``dagger'' board to
|
|
be revived.
|
|
|
|
After changing the console path, the machine has to be power cycled
|
|
for the changes to take effect.
|
|
|
|
In most cases the primary boot device path is already set to the right
|
|
value. If not, it is advised to run:
|
|
|
|
BOOT_ADMIN> search
|
|
|
|
to display the list of all bootable devices before choosing one with:
|
|
|
|
BOOT_ADMIN> path primary SCSI.TARGET.LUN
|
|
|
|
Substitute FWSCSI or SESCSI for SCSI if it is displayed as such in the
|
|
path list obtained from ``search'', and use the TARGET and LUN values
|
|
matching the device intended as the boot device.
|
|
|
|
To set up autoboot, use the configure option:
|
|
|
|
BOOT_ADMIN> co auto boot on
|
|
|
|
or if your machine has the old style PDC interface:
|
|
|
|
BOOT_ADMIN> autoselect on
|
|
|
|
Please refer to the boot(8) manual page for more information on PDC
|
|
settings and boot commands.
