How Do I Boot the Generic Kernel?


Bring the system down to console mode and set the boot register to 3 by
entering "pboot 3.".  This will prompt for a boot file (bit value of 1) and
boot to single user mode (bit value of 2):

   #0>pboot 3.00000002      /* The two register bit values added together = 3 */
                            /* previous value is displayed (00000002 here) */

Enter 'fb' to boot:

   #0>fb 
   Reset Backplane          /* The system displays these messages as it boots */
   Initialize Interrupts
   Set Run Mode
      CPU 0   CPU 1

At the ':' prompt, enter "unix.generic":

   INIT: :option: boot to single user mode.

   INIT: :SINGLE USER MODE

   Type Ctrl-d to proceed with normal startup,
   (or give root password for Single User Mode): 
   Entering Single User Mode

   #

At this point, the system is booted to single user mode and will prompt for
the root password.  After you log in, run idmknod as follows:

   # /etc/conf/bin/idmknod

This will remake all device files, giving them the correct major and minor
numbers.  Failure to perform this step will prevent the system from
recognizing other devices such as other disks, tape drives, and boards that
you might have in your system.

NOTE:  It is NOT recommended that you go into multiuser mode with the
generic kernel because it is provided only for system recovery purposes.

See idmknod(1M) for details.
