APPENDIX B \- LOADING THE TAPE MONITOR
This section describes how the bootstrap monitor located on
the first tape of the distribution tape set may be loaded.
This should not be necessary, but has been included as a fallback
measure if it is not possible to read the distributed
console medium. \fBWARNING\fP: the bootstraps supplied below
may not work, in certain instances on an 11/730 because they
use a buffered data path for transferring data from tape to
memory; consult our group if you are unable to load the
monitor on an 11/730. All of the addresses given below refer
to the first SBIA on the 8600.
To load the tape bootstrap monitor, first
mount the magnetic tape on drive 0 at load point, making
sure that the write ring is not inserted.
set the reboot switch on an 11/780 or 11/730 to off;
on an 8600 or 11/750 set the power-on action to halt.
(In normal operation an 11/785, 11/780, or 11/730
will have the reboot switch on,
and an 8600 or 11/750 will have the power-on action
If you have an 8600 or 11/780 give the commands:
Then, on any machine, give the init command:
key in at location 200 and execute either the TS, HT, TM, or MT
bootstrap that follows, as appropriate. \fBNOTE\fP: All of the addresses
given in this section refer to the first SBIA on the 8600.
Also, the VAX 8200 console does not accept
the ``D +'' command, so the second command becomes ``D 204 D05A0000'',
the third ``D 208 3BEF'', the fourth ``D 20C 800CA00'', the fifth
``D 210 32EFC1'', and so forth. Alternatively, you could
try booting BOOT58 via ``B/R5:800'' with a diagnostic floppy.
The machine's printouts are shown in boldface,
explanatory comments are within ( ).
You can use `delete' to erase a character and `control U' to kill the

N.B.: uba and umem addresses can be determined algorithmically
on 8200 machines as follows:
uba(\fInode\fP) = 20000000 + (2000 * \fInode\fP)
umem(\fInode\fP) = 20400000 + (40000 * \fInode\fP)

If the tape doesn't move the first time you start the bootstrap
program with ``S 200'' you probably have entered the program
incorrectly (but also check that the tape is online).
Start over and check your typing.
For the HT, MT, and TM bootstraps you will not be able to see the
tape motion as you advance through the first few blocks
as the tape motion is all within the vacuum columns.
XXX this next step is unnecessary! the register are still correct,
at least for the TS bootstrap XXX

address of the device registers or unit number from one of:

You are now talking to the tape bootstrap monitor.
At any point in the following procedure you can return
to this section, reload the tape bootstrap, and restart the
procedure. The console monitor is identical to that
loaded from a TU58 console cassette, follow the instructions
in section 2 as they apply to this device. The only
exception is that when using programs loaded from the
tape bootstrap monitor, programs will always return to
the monitor (the ``='' prompt). This saves your having
to type in the above toggle-in code for each program to
