Example 4–14 (Cont.): Patching the EEPROM with EVUCA — Part 2
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 continues. 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 availiable
and what devices they support (see
15
).
16. CPU 2 and CPU 1 have same 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
17
. Since the ROM is an older revision,
the devices the primitives support are not printed.
18. CPU 5 and 6 are now the same
18
.
