TEST
Command Description
A0 A0 Runs user-defined script. Enter T 9F to create.
A1 A1, 0 Primary power-up script; builds memory bitmap; marks
hard single-bit errors and multi-bit errors. Continues on
error.
A3 A3, A4 Runs power-up tests, halts on first error.
A4 A4 Loops on A3. Press
Ctrl C
to exit.
A6 A6 Memory test script; initializes memory bitmap and marks
only multiple bit errors.
A7 A7, A8 Memory test portion invoked by script A8. Reruns the
memory tests without rebuilding and reinitializing the
bitmap. Run script A8 once before running script A7
separately to allow mapping out of both single-bit and
double-bit main memory ECC errors.
A8 A8 Memory acceptance. Running script A8 with script A7
tests main memory more extensively. It enables hard
single-bit and multibit main memory ECC errors to be
marked bad in the bitmap. Invokes script A7 when it has
completed its tests.
A9 A9 Memory tests. Halts and reports the first error. Does not
reset the bitmap or busmap. It is a quick way to specify
which test caused a failure when a hard error is present.
AD AD Console program. Runs memory tests, marks bitmap,
resets busmap, and resets caches. Calls script AE.
AE AE, AD Console program. Resets memory CSRs and resets
caches. Also called by the INIT command.
AF AF Console program. Resets busmap and resets caches.
B2

B2 Runs extended tests, calls the BF script, then loops.
Press
Ctrl C
to exit.
B5 B5 Runs extended tests, then loops. Press
Ctrl C
to exit.
BF

BF Runs tests requiring loopback connectors for QUART,
SYNC, and, ASYNC options if present. Press
Ctrl C
to
exit.

Scripts AD, AE, and AF exist primarily for console program; error displays and progress messages
are suppressed (not recommended for CSE use).

B2 and BF require loopback connectors.
