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 EEPROM.
These tests are divided into the following groups:
BUMP Quick I/O Test Group
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 EEPROM, and TOD
(Time-Of-Day).
JTAG (Joint Tests Action Group) Test Group
These tests check the chip-to-chip connections using the JTAG
features.
Direct I/O Test Group These tests check the accessibility of the Standard and Direct I/O
components from the CPUs: IONIAN, NVRAM access, EPROM
access, TOD, and the diskette.
CPU Test Group These tests are performed by all of the processors and check the
status of the CPU cards: processor, address translation, L1 and L2
caches.
DCB (Data CrossBar) and Memory Test Group
These tests check the status of the system planar and memory
cards: data/address lines accessibility, memory components, ECC,
memory refresh (CPU checkstop).
Interrupt Test Group These tests collectively check the interrupt system: BUMP-CPU,
CPU-CPU (CPU checkstop).
MCA Test Group Not applicable
CPU Multiprocessor Test Group
These tests check the multiprocessor mechanisms, atomic
instructions, cache coherency, main memory sharing, and
multiresources sharing.

The following is an example of the output when running these PON tests:
***************
* PON TESTS *

Note that the PON test can be suppressed if the
fast IPL flag is enabled through
SystemGuard.
