BOOTS.DOC -- Changes from V22(105) to V23(114)
June 1979
1.0 SUMMARY
This version of BOOTS incorporates full support for the KS10 processor
and additions to support all eight RH20 controllers on the KL10
processor. Support for the KA10 processor has been removed.
2.0 EXTERNAL CHANGES
None.
3.0 KNOWN BUGS AND DEFICIENCIES
If BOOTS is assembled for the KL10 or KS10 with FT22BIT turned on, the
version which is written onto disk packs will go into a page fault
loop whenever the monitor reads it to do an auto dump/reload sequence
if the CCL text at BOOTXT in COMMON crosses a page boundry.
4.0 INSTALLATION INSTRUCTIONS
None.
5.0 INTERNAL CHANGES
A new feature test switch FTKS10 has been added for conditional
assembly of BOOTS that supports the KS10 with RH11. Code has also
been added to support eight RH20's.
6.0 SUGGESTIONS
None.

BOOTS.DOC -- Changes from V22(104) to V22(105)
August 1978
1.0 SUMMARY
The main reason for this release is to fix 2 bugs in V22(104).
2.0 EXTERNAL CHANGES
None.
3.0 KNOWN BUGS AND DEFICIENCIES
If BOOTS is assembled for the KL10 with FT22BIT turned on, the version
which is written onto disk packs will go into a page fault loop
whenever the monitor reads it to do an auto dump/reload sequence if
the CCL text at BOOTXT in COMMON crosses a page boundry.
4.0 INSTALLATION INSTRUCTIONS
None.
5.0 INTERNAL CHANGES
A bug in V22(104) which could cause BOOTS to hang, without ever typing
its prompt, when the KL10 was just powered up has been fixed. A bug
has been fixed which would cause BOOTS not to be able to read from an
RH20 after a data error on that controller.
6.0 SUGGESTIONS
None.

BOOTS.DOC -- Changes from V21C to V22(104)
March 1977
1.0 SUMMARY
The main reason for this release of BOOTS is to fix a bug in version
21 which caused BOOTS to have to be restarted under certain errors
which can occur on an RP04/RP06.
2.0 EXTERNAL CHANGES
Paper-tape BOOTS (or the version gotten by loading it from the
front-end of a KL10) now starts by typing its version number. Before
every command line is asked for BOOTS now types a prompt "<BTS>",
which indicates that it is ready for a command. Paper-tape BOOTS can
now be assembled so that it will work on either an RH10 or an RH20.
The BOOTS which is distributed on the KL10 front-end tape has been
assembled to work on either. The names of the bootstraps are now
BT128K and BT256K, for use on a 128K or 256K KL10.
Note that the BOOTS which is written on blocks 4-7 of a disk pack does
not have these changes, it still must be assembled for either an RH10
or RH20, and will not work on the "wrong" one. Neither does it type
its version number nor prompt before each command.
3.0 KNOWN BUGS AND DEFICIENCIES
If BOOTS is assembled for the KL10 with FT22BIT turned on, the version
which is written onto disk packs will go into a page fault loop
whenever the monitor reads it to do an auto dump/reload sequence if
the CCL text at BOOTXT in COMMON crosses a page boundary.
4.0 INSTALLATION INSTRUCTIONS
None.
5.0 INTERNAL CHANGES
A bug in version 21C, distributed with the 6.02A combined LIR, which
made it necessary to type the structure name as well as the file name
has been fixed. If an RP04/RP06 is disabled and then enabled, BOOTS
will still be able to read from it without restarting.

1.0 SUMMARY
The main reasons for this release of BOOTS are to support the 1088,
RP06, and RH20 LIRs.
2.0 EXTERNAL changes

5.0 INTERNAL changes
A new feature test switch has been added FTRH20 which defaults off.
If this feature test switch is turned on, BOOTS will be able to
load/dump from/to an RH20 control/channel. However, it will no longer
be able to operate an RH10 controller (See section 3 for more
details). Also, BOOTS has been changed to support loading and dumping
from/to RP06 packs. Finally, to implement 1088 and RH20 support,
BOOTS V21C uses exec page table relative addressing for DTE
communications rather than page 0 communications locations. This
requires that MON.BIN (V5A or later) and KLDCP (V11 or later) be used
with BOOTS V21C. These files are included on the KL10 front end
DECtape distributed with the LIRs.

BOOTS.DOC -- Changes from V20 to V21
October 1975
1.0 SUMMARY
The main purpose of this release of BOOTS is to fix a bug in version
20 of BOOTS which caused it to go into a page fault loop when loaded
by the 6.02 monitor on a KI10 if the feature test switch FT22BIT is
turned off in BOOTS. Version 21 also supports loading and dumping on
a KL10 with more than 256K of memory, and, with this version, auto
dump/reload wfile no longer apply.

BOOTS.DOC -- Changes from V17 to V20
July 1975
1.0 SUMMARY
A number of feature test switches have been incorporated into BOOTS in
order that it may support bootstraping from and dumping to several
devices from files in SAV and/or EXE format on KA10, KI10, or KL10
processors. In particular, with version 20 it is possible to make a
paper tape BOOTS which in addition to supporting the KL10 processor,
can read/write SAV or EXE files from/to RM10B's, RD10s, RP02s, RP03s
and RP04s. It is also possible to make a BOOTS to be written onto
disk packs by WTBOOT which is capable of dumping up to 4096K of core
on KI10 or KL10 based systems (the 6.02 monitor is required for this
feature). Also, BOOTS has been changed to display a fixed error code
between 1 and 16 in the lights (type the letters B through O on the
operator console of the KL10) whenever it encounters an error while it
is loading or dumping.
2.0 EXTERNAL CHANGES
BOOTS must be assembled with the appropriate feature test switch
settings to produce a BOOTS.REL file to be loaded with WTBOOT to take
advantage of features which are available in BOOTS but which are not
normally turned on. The paper tape version of BOOTS is now three
pages (page=512 words) long (2 code pages and a data page) so dumping
crashes with paper tape BOOTS is not recommended if it can be avoided
since an additional page of information which would be dumped by the
BOOTS read from a disk pack will be lost. BOOTS displays the
following error codes in the lights (or types the specified letter on
the KL10) to indicate what specific problem it encountered while
reading or writing.

5.0 INTERNAL CHANGES
There are now 10 feature test switches in BOOTS. For the purpose of
making a paper tape version of BOOTS, these feature test switches can
be ignored. However, to make a BOOTS.REL which is to be loaded with
WTBOOT to write BOOTS on blocks 4-7 of disk packs, it is necessary to
turn off some of the switches. The feature test switches which are
currently implemented in BOOTS are:
FTKA10, include support for KA10 processors
FTKI10, include support for KI10 processors
FTKL10, include support for KL10 processors
FTSAVE, include support for SAV files
FTEXE, include support for EXE files
FTFHD, include support for RM10Bs and RD10s
FTDPC, include support for RP02s and RP03s
FTDHX, include support for RP04s
BTS20.DOC Page 12
FT22BIT, include support for dumping more than 256K
FTWTBOOT, assemble BOOTS to be loaded with standard (field image)
WTBOOT. Defaults to on and would normally be on when
configuration dependent BOOTS.REL files are produced to
be loaded with WTBOOT.
In the paper tape version of BOOTS, all of the above feature test
switches (except FT22BIT) are normally turned on so paper tape BOOTS
will support reading/writing both SAV and EXE format files from/to any
supported device on a KA10, KI10 or KL10 processor. See BOOTS.MEM for
assembly instructions for producing a paper tape version of BOOTS.
In general, it is not possible to assemble BOOTS to load with WTBOOT
such that it will support EXE files and more than one type of device
and still have it be small enough to fit on blocks 4-7 of a disk pack.
Therefore, the BOOTS configuration which will most commonly be used
should be assembled and loaded with WTBOOT and written on all disk
packs, e.g., RP02/RP03 BOOTS should be written on all packs if the
monitor is normally on an RP02/RP03 pack and crashes are normally
dumped on CRASH.SAV or CRASH.EXE on an RP02/RP03 pack.

BOOTS.DOC -- Changes from V16 to V17
January 1975
1.0 SUMMARY
BOOTS version 17 supports RP04's. However, to keep the size of BOOTS
under 1K, something else had to go. The choice was to put fixed head
disk support (RC10, RM10B) under a conditional assembly switch. If
FTFHD=-1 (the default value), then BOOTS will talk to RC10's, RP02's,
and RP03's (but NOT RP04's). If FTFHD=0, then BOOTS talks to RP02's,
RP03's, and RP04's (but NOT RC10's).
BOOTS version 17 supersedes all previous versions of BOOTS.
2.0 EXTERNAL CHANGES
BOOTS can now access RP04's. All commands and operator interface
remain unchanged.
3.0 KNOWN BUGS AND DEFICIENCIES
BOOTS will only dump or load the first 255K of physical core. This is
true even if 4096K exist.
BOOTS may not correctly dump into a file which is on a multi-unit file
structure if the file is split across units.
BOOTS still does not support the RS04.
A self-relocating paper tape version is still recognized as a good
idea, but has not been implemented.
4.0 INSTALLATION INSTRUCTIONS
Since the default value of FTFHD produces BOOTS without RP04 support,
one must assemble BOOTS with a parameter file defining FTFHD==0 to
obtain an RP04 BOOTS. The version of WTBOOT.CTL which accompanies the
RP04 LIR contains the command sequence to accomplish this. It is as
follows:
BTS17.DOC Page 14
.MAKE BPARAM.MAC
*I FTFHD==0
*$EX$$
.COMPILE BPARAM+BOOTS
The installation instructions for paper tape versions of BOOTS are
similarly affected. See BOOTS.CTL and WTBOOT.CTL.
5.0 INTERNAL CHANGES
The only internal changes are the definitions of the FTFHD and FTDH
feature test switches and the use of these switches to conditionally
assemble either the existing code for fixed head disks or the new code
which handles RP04's.

BOOTS.DOC -- Changes from V15 to V16
January 1974
1.0 SUMMARY
This release adds 3 new features for 5.07/6.01:
1. BOOTS now supports up to 4096K memory using the DF10C in
22-bit mode.
2. BOOTS may be given a command string by storing a byte pointer
to the string in location 777 relative to the starting
address of BOOTS. This lets the monitor reload itself.
3. BOOTS stores the serial number of the CPU in low core. This
allows a 1077 monitor to use the same CPU as the master.
BOOTS version 16 supersedes all previous versions of BOOTS. This
version supports the DATE75 project.
2.0 EXTERNAL CHANGES
None.
3.0 KNOWN BUGS AND DEFICIENCIES
BOOTS will only dump or load the first 255K of physical core. This is
true even if 4096K exist.
BOOTS may not correctly dump into a file which is on a multi-unit file
structure if the file is split across units.
BOOTS does not support the RS04 or RP04.

BOOTS.DOC -- Changes from V13 to V15
March 1972
1.0 SUMMARY
This release enables BOOTS to service RP03 disk drives. Version 15
does not support RP01's. No bugs have been reported to the released
version 13.
2.0 EXTERNAL CHANGES
None.
3.0 KNOWN BUGS AND DEFICIENCIES
RP01 drives no longer supported. In the future make a paper tape
bootstrap loader which determines how big memory is so can have only
one size for paper tape too. Version 15 still requires a separate
assembly for each size paper tape version.
4.0 INSTALLATION INSTRUCTION CHANGES
None.
5.0 INTERNAL CHANGES
All references to RP01 drives have been removed. Bit R.TYPE=1 in
AC(F) now means drive is RP03 if RP10 controller, instead of RP01.

BOOTS.DOC -- Changes from V4 to V13
April 1971
1.0 SUMMARY
This release adds a few new features to BOOTS. No bugs have been
reported to the released version 4. BOOTS is now location independent
so that a single copy can be written on a disk and loaded into the top
of memory no matter how big memory is. BOOTS now prints ? as well as
bell on all errors. BOOTS indicates the type of error by displaying
in the lights an error PC. See new, faster monitor crash proecdures
in 5.03 monitor release. See also WTBOOT writeup available with 5.03
release. WTBOOT is a program to write BOOTS onto blocks 4 through 7
of disk packs.
2.0 EXTERNAL CHANGES
Whenever an error occurs, BOOTS types both a bell and a ? followed by
a carriage return line-feed. It also displays the error PC in the
lights. The error PCs are as follows:
XXX061 no comma inside [ ]'s
XXX131 on /G no starting address specified previously
XXX134 not a legal command or decimal number
XXX151 file not found on /L or cr command
XXX173 data error on read
XXX201 file not found on /D
XXX236 data error on write
XXX305 bad RIB
XXX326 RIB does not have code word 777777
XXX334 premature EOF reading RIB
XXX622 attempt to read block 0
XXX713 logical block number exceeds size of disk
3.0 KNOWN BUGS AND DEFICIENCIES
None. For future make a paper tape bootstrap loader which determines
how big memory is so can have only one size for paper tape too.
Version 12 still requires a separate assembly for each size paper tape
version.
