<REFERENCE>PRIME>BORIS>MAKECDC340
Prime's drive pricing was quite high, so there was always an aftermarket of third party vendors selling disk and tape drives (and even memory and controllers) to Prime sites.
Among other drives, EMC sold the CDC 340 MB FMD (aka 9715-340). The PRIMOS MAKE command had compiled into it the parameters of all of the disk drives Prime sold and supported. To format a disk with different geometry, it was necessary to have a customized MAKE program. These instructions describe how to use the simple debugger to "slime patch" a vanilla Prime MAKE program.
It was necessary for third party vendors to take this kind of approach, since distributing the modified program themselves would have placed them in violation of Prime's copyrights.
This file was typed into a BORIS customer machine in the Detroit area by a member of the MLS staff. The manager of BORIS Customer Service (Kevin McQueen) downloaded it from the customer site via a dialup modem. I've left the assorted logout messages, backspacing, double echo and such for flavor.

Hi Y'all.
I have decided to type in most of the Customer portion of the CDC 340mb DRIVE
INSTALLATION AND FORMATTING MANUAL FOR PRIME SYSTEMS that was supplied to us
from EMC. The introduction and reference to pre-REV 19.3 is left out.
Installation Instructions for CDC personel
GENERAL
The drive has been setup at our factory for installation onto a Prime System.
The hardware has been modified to be compatible with Prime Disk Controllers,
either the 4004 or 4005. Reliability testing has been performed and a Primos
file system has been installed on the drive. Manufacture badspot information
has also been registered in the file system. As the disk contains valuable
data it SHOULD NOT BE WRITTEN ON. The delivered configuration is:
9 sectors/track
internal switches set
internal jumpers in place
Index/Sector in "A" cable
Primos file systems installed.
Procedure (Ref. doc. #83324760 Hardwar Maintenance Manual)
1) Perform all necessary steps as described in section 3 of the manual.
2) It is recommended that a field test unit such as TB216A or TB2A3A be
used to verify the operability of the drive. As there is valuable
information on the drive, the field test unit should only be used to
READ the drive. It is not necessary to either format or write to the
drive.
3) Install cabling to the Prime Controller ensuring the proper orientation
of the connectors. The connectors are not keyed, so it is possible to
incorrectly install the connectors.
4) Install the supplied grounding cables in a "star" configuration to tie
each drive individualy to the Prime controller chassis (do not "daisy-
chain" ground cables from drive to drive).
5) The disk can now be "added" to Primos using the ADDISK command. The base
physical device number is 6060. The controller number and unit number
should be added to the base number. The disk should now be added with
no errors. If errors occur, they are most likely either cabling
problems, controller problems, or the disk is not online.
Customer Installation Procedure.
1) Ensure that the CDC service engineers have followed the EMC supplied
installation procedure.
2) The disk should, at this point, already be added the the system under the
partition name TEST.
3) Create a directory in <TEST>MFD. This directory will be used to copy
files into. Copy enough files into the directory to fill the partition
to approximatels 20% of its capacity.
4) When the copy is complete, the disk should be shut down and FIX_DISK should
be run on the partition. It should report no errors. Since the file
system is REV 19.3, earlier revisions will report "information in reserved
areas." This can safeley be ignored.
5) When steps 3 and 4 are successfully completed, the disk can either be used
as is or re-partitioned using EMC_MAKE. EMC_MAKE is a "patched" version
of the normal MAKE. Procedures are included which will enable you to
create EMC_MAKE.
Repartitioning the Drive
The drive has been formatted and all of the manufacturer-supplied bad spots
have been placed in a Primos file system partition. The partition contains
24 heads, starting at head offset 0, in other words the entire disk is on
partition.
To re-parition this new disk drive to your system, you must create and execute
the program EMC_MAKE, which is suitable for formatting the 340 MB EMC/CDC
model 9715 disk drives. This is done by altering a copy of the Prime-supplied
program MAKE. This is necessary because the geometry (number of heads and
number of tracks) of the drive dirrer from that of any currently supported Prime
disk drives. There are 24 heads and 711 cylinders available on the EMC/CDC
model 9715. There are 19 head and 823 cylinders on a standard Prime CDC 300
megabyte disk drive. The program EMC_MAKE writes the number of cylinders
available on the disk as part of the formatting process. The system
administrator chooses the number of heads per partition and number of partitions
per drive in the usual manner under Primos using the ADDISK command.
Note that there are 5 more heads available in the configuration than the
standard 300 MB drive. Thus there are physical device numbers describing
several possible disk organizations which are not listed in the tables of
Appendix A of the System Administrator's/System Operator's Manuals. However,
all the normal rules for constructing device numbers given there apply to this
drive with no exceptions. Thus, to create a single partition of 24 heads the
correct physical device number is 606X where X is twice the drive number. It
is strongly recommended that the System Administrator be familiar with the
construction of physical device numbers as described in Appendix A of the
Systems Administrator's guide.
Prime's MAKE has been changing slightly at each revision of Primos. Thus, the
creation of EMC_MAKE differs for each. Determine which revision or MAKE you
have by attempting to run the program with no arguments. Follow the
instructions for your particular version of MAKE. In the following instructions
BOLDFACE (in this case CAPITALS) indicates the input you must supply to create
your version of EMC_MAKE. Lower case is used to explain in detail each step.
The usual Prime convention of using "/*" to indicate comment fields is followed.
DO NOT enter the "/*" nor anything to the right of "/*".
REALCOMP'S version of MAKE is 19.3.4.
/* Procedure to create EMC_MAKE for Revision 19.3 of Primos:
/* revision 19.3 of MAKE
ABBREV -OFF /* turn off abbreviations to avoid possible
/* confusion.
FILMEM ALL /* set user's segment 4000 to zeros
RESTORE CMDNC0>MAKE /* substitute correct pathname if needed.
PM /* obtain the program's RVEC and note PM.
/* from what I can gather from the copy of these instructions the Prime will
/* return the next 2 statements.
SA, EA, P, A, B, X, K = /* starting address, ending address, etc.
66 34000 1000 * * * * /* which must agree with these.
note: The values for A,B,X and K are site specific, and as such will vary.
The values of each should be noted as they will be used in the
subsequent SAVE command.
If you do NOT observe the above numbers, do NOT continue. Start again.
Use PSD, one of Prime's low level debuggers, to examine and alter the
executable code of MAKE. Enter only the 1st upper case letter of each
PSD command. If you are unfamiliar with PSD, see chapter 18-21 of the
Assembly Language Programmer's Guide.
PSD
note: PSD has no line or character kill characters. If a mistake is made,
type / and re-enter the command.
"$" below is PSD's prompt character. Enter :O to display all data as
octal numbers.
/* confirm that we have found the correct locations and contents.
$:Octal
$Search 1000 34000 1465
/* Prime will return the following - thd
12340 1465
/* continue with:
$Search 1000 34000 1467
/* Prime will return the following - thd
11441 1467
12341 1467
If the above 3 locations return the correct values then continue.
Otherwise quit since your version of MAKE does not match the desired
original file. Notify EMC.
$Update 12340 1305 /* alter the necessary locations
12340 1465 1305 /* receive confirmation confirmation that it is done
$Update 11441 1307
11441 1467 1307
$Update 12341 1307
12341 1467 1307
$Quit /* return to Primos command level
Save the modified program under a new name. This is a new executable
probram which may be retained for future use as necessary. Note
identical numeric arguments returned by PM command above.
SAVE EMC_MAKE 66 34000 1000 * * * *
Note: Enter the Previously recorded values for A, B, X, and K.
Check that the modification were successfully made by examining the
differences between the original MAKE and the Modified EMC_MAKE.

If the above numbers do not agree EXACTLY, do not execute the new

contact EMC.

END OF PROCEDURE TO CREATE EMC_MAKE FOR REVISION 19.3.
Installation of the New Partition Into the Promos File System
All of the disk partitions which are on line at any point in time constitute
the Primos File System. To effectiviely utilize the new partition, it must be
integrated inot the system. Integration involves defining the names in the new
MFD, setting ACL's, determining the disk quotas and putting the partition into
the back-up procedures. Each of these system administrator funcions are
described in the Prime Documentation.
THAT IS ALL I HAVE........
