LOAD PROGRAM FUNCTION
The diskette drive problems identified are head align-
The Load Program Function is selected from the CE ment, head sensitivity and stepper mechanism
Diagnostic Function Selection Menu to perform a soft IPL problems. If the head alignment is beyond the +1 or-l
of the customer program diskette. A soft IPL is an Initial range, a prompt will reference the head alignment
Program Load performed without turning the system off adjustment in the Product Support Manual. When head
and going through the normal paR and BAT sequence. sensitivity or stepper mechanism problems are found,
the prompt will reference a MAP.
This function may also be used to execute diskette MDls
from the opposite diskette drive.
DISKETTE UNIT (6360) HEAD ALIGNMENT
COMPATABILITY CHECK
This utility checks the compatability of the read/write head
alignment of two or more diskette drives by using one CE
diskette. One of three results will be displayed; return
codes, diskette drive problem, or unexpected diskette
failure.
The return codes of the diskette drives checked are
compared to determine which diskette drive(sl. if any,
need to be mechanically checked and/or adjusted with
the head alignment procedure in this manual.
The return codes +1, 0, or -1 are displayed, and
indicate the result of the check.
A variation in return codes between drives indicates the
head alignments are not identical. A variation of not
more than one, for example +1 and 0 or 0 and -1, is
generally acceptable.
If the variation between drives is more than one, for
example +1 and -1, the head alignment is not accept-
able and must be adiusted to reduce the variation to
one or less. Adiustments should be performed on the
smallest group of like return codes.
Unexpected diskette failures can occur during this test.
If this occurs, a prompt is displayed to re-run the test.
If problems continue, the MAPs should be used.

VERSION MODIFICATION (FESN/RVM)
The FESN/RVM utility is selected from the Group Selec-
tion Menu to identify and check the level of the customer
program diskette. When the utility is selected and the
program diskette is loaded, the program diskette name,
spelling support, the FESN, and the RVM is displayed.
The FESN and RVM are used to call report software
problems and are recorded on the I/PAR when a software
problem is found.
LlCENSEO PROGRAM GUIDELINES
ANO MEMORY CARD CONFIGURATION
Listed are guidelines for I BM Licensed Program memory
requirements. This list is only a guide since system con-
figurations and World Trade requirements may change the
memory requirement. The proper sales literature has the
latest requirements.

There are two types of memory card, Type A and Type B.
When replacing memory cards, care must be taken to
replace like card for like card. For example, a 160A card
must be replaced with a 160A card, and a 160B card must
be
replaced with a 160B card. This is necessary to ensure
proper operation of the system and to maintain machine
level control (MLC).
Memory sizes can be configured as follows:
