Rebooting from cdrom on the Sun station

In order to reboot a Sun (e.g., jaco) from the cdrom, it is essential that the cdrom be mapped to scsi ID 6.

You can then power up the computer. When you are in the setup screen, you can type:

Stop^A
holding down the Stop and A keys simultaneously.

Then, at the > prompt, type:

> b cdrom
Placing you back in the boot process.

If the issue is resetting the root password:

  1. Insert the startup cd and boot from cdrom as above.
  2. Select Mini-Root as the boot option.
  3. Select the option to install Mini-Root on sd0a.
  4. Mount the standard file system:

    mount /dev/sd0a /mnt

  5. edit the file that is now /mnt/etc/passwd so that the first line reads:

    root::0:1:Operator:/:/bin/csh

    which removes the root password.

  6. Reboot the system by typing: reboot
  7. Once the system is up, type: passwd and enter in your new desired password.
