There are other resident PON tests to check other system resources. These tests are a
subset of the SystemGuard maintenance offline tests, and reside within the flash EPROM.
These tests are divided into the following groups:
BUMP Quick I/O Test Group
JTAG (Joint Tests Action Group) Test Group
Direct I/O Test Group These tests check the accessibility of the Standard and Direct I/O
CPU Test Group
DCB (Data CrossBar) and Memory Test Group
Interrupt Test Group
MCA Test Group
CPU Multiprocessor Test Group
2
I C Bus Test Group
The following is an example of the output when running these PON tests:
.. Bump [01.01.00] DEBUG LINE TEST
.. Bump [01.02.00] S1 ASL (BUMP) TEST
.. Bump [01.03.01] S2 ASL (REM.) TEST
.. Bump [01.04.00] S3 ASL (SPE.) TEST
.. Bump [01.05.00] FLASH EP. CONTENT TEST
.. Bump [01.06.00] NVRAM CONTENT TEST
.. Bump [01.07.00] EPROM CONTENT TEST
.. Bump [01.08.00] TOD TEST
.. Bump [01.09.00] FLOPPY–D CNT. TEST
.. Bump [01.10.00] BPP REGISTERS TEST
.. Bump [01.11.00] MISC. REGS TEST
.. Bump [06.05.00] TOD–BUMP IT TEST
Note that the PON test can be suppressed if the fast IPL flag is enabled through
SystemGuard.

Operator Guide
These tests check the accessibility and the functions of the
standard and direct I/O components from the BUMP: Async lines
(S1, S2, and S3), EEPROMs, NVRAM, Flash EPROM, and TOD
(Time-Of-Day).
These tests check the chip-to-chip connections using the JTAG
features.
components from the CPUs: IONIAN, NVRAM access, EPROM
access, TOD, and the diskette.
These tests are performed by all of the processors and check the
status of the CPU cards: processor, address translation, L1 and L2
caches.
These tests check the status of the system planar and memory
cards: data/address lines accessibility, memory components, ECC,
memory refresh (CPU checkstop).
These tests collectively check the interrupt system: BUMP-CPU,
CPU-CPU (CPU checkstop).
Not applicable
These tests check the multiprocessor mechanisms, atomic
instructions, cache coherency, main memory sharing, and
multiresources sharing.
