Example 3–13 (Cont.): Patching the EEPROM with EVUCA — Part 2
The primary CPU was not updated.
Secondary CPU 05, was successfully updated.
Current ROM and EEPROM revisions for each CPU are:

13. Test 4 creates a new updated EEPROM image in memory (see
13
).
Several boot primitives are available. Those that are permanent
reside in ROM; those that are selectable or are patched reside in
the EEPROM. If all boot primitives fit, EVUCA will not go through
a selection process. However, if all primitives do not fit, the user is
shown all the boot primitives available and prompted to choose which
primitive is not wanted. If enough space is available, EVUCA will
continue. If enough space is not available, the user must choose another
unwanted primitive. This process continues until space is available
for the remaining primitives.
14. Once the primitives fit, the EEPROMs are updated and the message
noted by
14
is printed.
15. Later ROM revisions identify both what boot primitives are available
and what devices they support (see
15
).
16. CPU 2 and CPU 1 have the same ROM revision and have the same
boot primitives
16
.
17. CPU 5 has been patched, and test 5 shows the primitives in ROM
followed by those in EEPROM (See
17
in Example 3–13). Since the
ROM is an older revision, the devices the primitives support are not
printed.
18. A final list of current ROM and EEPROM revisions is printed
18
.
