BOOT11.DOC -- Changes from V4 to V4A(46)
|
||
June 1979
|
||
|
||
|
||
|
||
1.0 SUMMARY
|
||
|
||
This is a maintenance release of BOOT11 intended to correct
|
||
deficiencies in Version 4.
|
||
|
||
BOOT11 has been improved to function properly in the following areas:
|
||
|
||
1. Dual CPU,
|
||
|
||
2. Timing for PDP-11/40's, and
|
||
|
||
3. DL10 8K option.
|
||
|
||
4. Logs all dumps and reloads via DAEMON monitor calls.
|
||
|
||
BOOT11 has also had the following software corrections made:
|
||
|
||
1. Displays the LOCK UUO error code when attempt to lock fails,
|
||
|
||
2. Operates correctly when requested to LOCK above 112K on a KI
|
||
or anytime on a KL10,
|
||
|
||
3. Requires a port switch only when more than one PDP-11 exists
|
||
on the DL10, and
|
||
|
||
4. Prints CPU serial numbers greater than 999 in dump heading
|
||
format.
|
||
|
||
This version of BOOT11 has been tested under 7.00 monitors on KI10 and
|
||
KL10 processors.
|
||
|
||
BOOT11 is documented in the DECsystem-10 Software Notebooks
|
||
Specifications section.

2.0 EXTERNAL CHANGES
|
||
|
||
|
||
2.1 User Interface
|
||
|
||
If a total of only one PDP-11 exists on all DL10's and it is connected
|
||
to port 0, there is no change to the user interface for this program.
|
||
Also, if the user always specifies the DL10 port number, there is no
|
||
change to the user interface for this program.
|
||
|
||
If the total number of PDP-11's which exist on all DL10's on the
|
||
system is greater than one (including the case of just one PDP-11
|
||
connected to some port other than port 0), BOOT11 now requires that
|
||
the user supply the appropriate port number.
|
||
|
||
|
||
2.2 Documentation Changes
|
||
|
||
BOOT11 requires that the port number be explicitly given when the
|
||
total number of PDP-11's which exist on all DL10's on the system is
|
||
greater than one. The format of this switch is not changed; namely,
|
||
the user supplies:
|
||
|
||
/PORTNO:n
|
||
or /P:n
|
||
|
||
where n is the port number in the range 0-7.
|
||
|
||
If BOOT11 is not given a port switch and determines that one is
|
||
required (e.g, PDP-11's exist on ports 0, 1, and 2), it responds with:
|
||
|
||
"PDP-11's EXIST ON PORTS:
|
||
0 1 2
|
||
? PORT SWITCH REQUIRED
|
||
FILE:
|
||
|
||
to which the user should re-enter the command string and include the
|
||
appropriate port number.
|
||
|
||
The requirement for this switch has been added to BOOT11.HLP.

||
3.0 KNOWN BUGS AND DEFICIENCIES
|
||
|
||
The known bugs and deficiencies in BOOT11 Version 4A as of June 10,
|
||
1975, are:
|
||
|
||
Though this version corrects most timing problems, there can appear a
|
||
timing problem which aborts BOOT11 (with either a "PDP-11 won't
|
||
start - check halt switch" message or "PDP-11 took too long in
|
||
transfer loop" message). This seems to appear when two successive
|
||
commands are given which request the PDP-11 to start from stop or stop
|
||
from running. From timesharing, a re-try seems to always succeed;
|
||
from batch, where the commands are processed faster than the react
|
||
time of the PDP-11, this solution is inadequate. This problem does
|
||
not occur very often and seems to be dependent on the PDP-11 hardware
|
||
reaction time.
|
||
|
||
In the BOOT11 DUMP routine, heading format and paging may be done
|
||
wrong if there are many groups of zero memory being reported (although
|
||
all data is correct).
|
||
|
||
|
||
|
||
4.0 INSTALLATION INSTRUCTIONS
|
||
|
||
There are no changes to the installation instructions.
|
||
|
||
To install BOOT11, copy BOOT11.SHR and BOOT11.LOW from the
|
||
distribution tape to SYS:.

||
5.0 INTERNAL CHANGES
|
||
|
||
The Dual CPU change does a SET CPU UUO to allow BOOT11 to run on CPU 0
|
||
only. [Edit 35]
|
||
|
||
The bus timing constant for the PDP-11 is increased to make BOOT11
|
||
work on PDP-11/40's. [Edits 36 and 44]
|
||
|
||
BOOT11 locks on an even-numbered page boundary in order to function
|
||
properly with the DL10 8K option. [Edit 37]
|
||
|
||
BOOT11 displays the LOCK UUO error code (documented in the Monitor
|
||
Calls notebook) which is returned in the AC when the LOCK fails.
|
||
[Edit 40]
|
||
|
||
BOOT11 determines where the job is locked in core via a GETTAB to
|
||
locate the user's page map, rather than the page returned from the
|
||
LOCK UUO (which is a mapped page above 112K on a KI and always on a
|
||
KL10). [Edit 41] SPR 10-15583.
|
||
|
||
BOOT11 checks the command syntax for an explicit port switch. If the
|
||
port swtich is given, BOOT11 proceeds using that information. If the
|
||
port switch is not given, BOOT11 then checks the DL10(s) for the
|
||
existance of more than PDP-11 (via a DATAI). If only one PDP-11
|
||
exists and it is on port 0, no switch is required and BOOT11 proceeds.
|
||
If more than one PDP-11 exists (or a single PDP-11 exists on some port
|
||
other than zero), BOOT11 requires the user to re-enter the command
|
||
string and include the port switch. [Edit 42]
|
||
|
||
BOOT11 retrieves the CPU serial number from the monitor via a GETTAB
|
||
for output when a dump of a PDP-11 is requested. The field for this
|
||
serial number has been enlarged to allow up to four decimal digits
|
||
(9999). [Edit 43]
|
||
|
||
BOOT11 now logs all -11 dumps and reloads to DAEMON. [Edit 46]
|
||
|
||
|
||
|
||
6.0 SUGGESTIONS
|
||
|
||
None.
