Using
the
9000
Series
for
Quick
ROM
Testing
NOTE
Special addresses mentioned in the
followingparagraphs
are also
valid
for
9100
Series mainframes. However, they are
not
necessary
because the 9100 Series
provides
softkeys to directly access these
pod
functions.
The
recommended method
of
running
pod—
controlled
quick
testsfrom
the 9100 Series
is
given
under
a
separate
heading.
The Quick ROM test
is
specified in a
manner
similar to the Quick RAM test.
The
starting
and ending addresses are specified by writing to special addresses.
The
starting
address
is
defined by
a
WRITE
@
3X XXXX=0, where
XXXXX
is
the address to be used to start the Quick ROM test. The ending address and
address
increment are defined by a
WRITE
@ 3Y
YYYY=Z1, where
Y
YYYY
is
the desired ending address and Z
is
the optional increment.
If
Z
is
not
specified
or
is
specified as
0,
the increment
will
default to l. The
ending
address must be
greater
than
the starting address.
For
example,
to
specify a Quick ROM test over ROM addresses 0000
through
0FFF,
do the following two operations:
WH/TE @
30 0000=0
WRITE @
30 0FFF=1
The Quick ROM test begins execution
as
soon
as
the
operator
completes the
entry
of the ending address.
During
and after execution of the test, the
mainframe
will
not display any information
about
the progress or results of the
test unless requested by the operator. The test may be
aborted
before completion
by selecting
another
operation.
To
determine
if the Quick ROM test
is
still in progress, or what the test results
are, the mainframe
operator
should perform a
READ
@
ENTER
operation
(which commands
a
READ operation
at the last entered address). In response,
the pod
returns
a byte indicating the status of the test or the test results. The
status
codes and their meanings are shown in Table
3-5.
Read-only special addresses in the F0 30XX range
contain additional
informa-
tion about
the Quick ROM test, including errors and records
of
addresses used.
The special addresses for the Quick ROM test are described in Table
3-5.
