You can disable the STOP+A key function on the SUN Microsystem’s keyboard. If someone entered the STOP+A function, it will do nothing to the system otherwise it will boot the Solaris into ok prompt.
Method 1
• Turn the keyswitch to the Lock position
Method 2
• Go to /etc/system and the following line inside it. Make sure to reboot to apply the changes.
# vi /etc/system set abort_enable = 0
Method 3
• Go to /etc/default/kbd and remove the comment before ‘KEYBOARD_ABORT‘.
# vi /etc/default/kbd KEYBOARD_ABORT=disable
