5.2 E̲P̲R̲O̲M̲ ̲C̲O̲N̲T̲E̲N̲T̲S̲
This section describes the use of the SCM PROM and
EPROM in an operational PC.
5.2.1 A̲P̲P̲L̲I̲C̲A̲T̲I̲O̲N̲ ̲S̲W̲
The application SW system generated by the SYSGEN utility
as shown in section 4.1 is stored in EPROM, memory
page 2 from #400. The upper address in EPROM should
not exceed #DFFF.
System initialization is performed by copying the EPROM
from address 0 thorugh #DFFF to RAM memory page 0,
address 0 through #DFFF.
Address #400 in page 0 may then be used for the CR80
'load process' instruction (LDN), which will start
the AMOS INIT program.
The EPROM to RAM copying is performed by invocation
of the Maintenance Controller (MAC) INIT command.
5.2.2 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲C̲o̲n̲t̲r̲o̲l̲l̲e̲r̲ ̲(̲M̲A̲C̲)̲
The MAC software is located in EPROM at memory page
2 from address #E000. MAC SW must not exceed #F7FF.
Initialization of MAC is performed by copying the EPROM
from #E000 to #F7FF to RAM memory page 0 #E000 to #F7FF.
MAC is loaded by the 'load process' instruction (LDN)
with #E000 used as base.
MAC is automatically loaded from EPROM whenever a masterclear
(programmed or manual) occurs, or during power up.
A small program located in the SCM PROM (page 0, #F800
through #FFFF) with base #FFE0 is responsible for loading
the MAC.
In an operational PC PU this program will substitute
the ordinary bootloader utilities usually implemented
in the SCM PROM such as the AMU mentioned in section
3.
5.2.3 G̲E̲N̲E̲R̲A̲T̲I̲O̲N̲ ̲O̲F̲ ̲E̲P̲R̲O̲M̲'̲s̲
In order to generate a set of 2764 EPROM's use the
SYSGEN utility version 0304. In the boot module generated
by SYSGEN applications programs should start at addresses
which are multiple of 8K words. Smaller packages may
be held together within 8K word blocks.
This blocking is accomplished by using the FILL options
in SYSGEN V0304. If module A has a start address plus
length below address #8000, and module B should start
at #8000 enter the following lines during SYSGEN dialogue:
.
.
.
file name for module A
FILL
#8000
file name for module B
.
.
.
.
SYSGEN is performed in the directory a**PC.D*SYSTEM.D*SYSGEN.D.
N̲o̲t̲e̲ ̲t̲h̲e̲ ̲s̲i̲z̲e̲ ̲o̲f̲ ̲t̲h̲e̲ ̲S̲Y̲S̲G̲E̲N̲ ̲o̲u̲t̲p̲u̲t̲ ̲f̲i̲l̲e̲.
In order to generate a complete file to be prommed
enter the directory …0c…a**PC.D*SYSTEM.D*CONCAT.D.
The file PROMFILE.B is now to be generated to match
the 64K words EPROM contents. PROMFILE.B is a concatenation
of four files:
̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲
̲ ̲ ̲ ̲ ̲ ̲
SIZE FILE
̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲
̲ ̲ ̲ ̲ ̲ ̲
2048 bytes HEADER ̲FILL.B
C bytes a**PC.D*SYSTEM.D*SYSGEN.D*C
X bytes FILL.B
a**PC.D*MAC.D*TEST.D*SYSGEN.B
̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲
̲ ̲ ̲ ̲ ̲ ̲
Since the fourth file containing MAC must start at
#E000 = 114688 bytes the required size of the intermediate
fill file FILL.B becomes:
114688 - 2048 - C = X bytes
FILL.B is produced by cutting off the first D-X bytes
of the file FILL.S using the CEDIT utility. D is the
size of the file FILL.S
Verify the concatenation process by utility BINHEX
on the file PROMFILE.B. The MAC Package should start
at #E000 with the special INIT module combined program/process
header.
To summaraize the concatenation process:
enter DO FILL.J and
DO CONCAT.J and
BINHEX I:PROMFILE.B
Verify that MAC is located at address #E000.
5.2.4 C̲H̲E̲C̲K̲S̲U̲M̲ ̲A̲D̲J̲U̲S̲T̲M̲E̲N̲T̲
To format the file for the PROM Programmer enter the
directory:
a**PC.D*SYSTEM.D*PROMGEN.D
The PC PROMGEN V0102 should be used.
Enter the command:
DO P ̲ALL.J
and write down the checksums for PROM files generated,
i.e. files PE15.B, PF15.B. PE18.B, PF18.B, ...., PE37.B,
and PF37.B.
Add all the above checksums for the PE ... - files.
Add all the checksums for the PF ... - files.
Calculate a hexadecimal byte number which will make
the PE sum end at 00 when added to it. This is the
LSByte adjustment number.
The MSByte checksum number is calculated as shown below:
sum of PE checksums = XXYY
sum of PF checksums = VVZZ
LSByte adjustment = #100-YY
MSByte adjustment = #100-(XX+1+ZZ)
Enter the MAC main module directory and add the LSByte
adjustment to the variable EPROM ̲CHECKSUM ̲LEAST, least
significant byte. Add the MSByte adjustment to the
variable EPROM ̲CHECKSUM ̲MOST, most significant byte.
Recompile, Link, and SYSGEN the MAC package in directory
PC.D*MAC.D*TEST.D.
After a new run of CONCAT and PROMGEN the new checksum
values are:
sum of PE checksums = XXYY = XX00
sum of PF checksums = VVZZ
where
XX + ZZ = #100
Checksumming the EPROM by adding words will result
in a checksum with four zeroes at its tail.
Mount two floppy discs with volume names PCUPPPER and
PCLOWER. Copy the PROM files to the floppy discs using
the command file COPY.J. Note how files are renamed
to match the PROM numbers on the CR8013 EPROM board.
Generation of PROMs using the DATA I/O connected to
the SSD departments CR80 is shown in appendix A.
Volumes PCUPPER and PCLOWER must be mounted on the
system.
The DATA I/O is set to control the data flow from the
CR80 by entering:
keyboard/select/D2/enter/start
On the nearby TEXAS silent enter the commands shown
in appendix A.
Verify the checksum and enter:
prog/start
on the DATA I/O SYSTEM 19
PROMs are labelled 2437-xx thru 2554-xx, where xx is
the PC versions.
PROM version numbers (xx) must be reserved for use
in PC. Furthermore, a new PC SW Delivery Status sheet
must be issued reflecting the SW package versions of
the currently released set of PROMs.
