2. Put the control panel’s lower key switch in the Update position (see
Section 3.3).
3. Put the control panel’s upper key switch in the Enable position, and
type CTRL/P at the console terminal to put the terminal in console
mode (see Section 5.3).
4. Move to the processor whose EEPROM contents you wish to restore.
Normally, all EEPROM contents will be the same. If you are restoring
the contents of the boot processor, proceed to the next step. If you
wish to restore the contents of a secondary processor, change the boot
processor using the SET CPU command (see Section 5.18.2).
5. At the prompt, enter RESTORE EEPROM. The console program
queries you, requiring your confirmation to proceed with the RESTORE
EEPROM operation.
6. Enter Y to indicate your intention to proceed. The restore process takes
less than 2 minutes to complete.
7. When the console prompt returns, the restore operation is complete.
Restored information includes:
Systemwide console parameters
(baud rate, interleave, terminal characteristics)
Saved boot specifications
Diagnostic patches
Console patches
Boot primitives
8. Rewind the TK tape.
9. Reset the system using the INITIALIZE command or the control panel
Restart button. All restored changes are visible following a system
reset.
10. Use the SHOW command to verify the contents of the EEPROM.
NOTE: With the UPDATE command you can restore EEPROM contents on
all secondary processors (see Section 5.24), but you must be sure all ROMs
are the same revision. The EVUCA program can also be used to restore the
EEPROM contents (see Appendix E ).
Because each system has its own identifying information stored in the
EEPROM, only the TK tape for that system should be used for a RESTORE
EEPROM operation.
