Changed the RESET button to *not* autoStart a machine when a Debugger is present, so that the Debugger can "cleanly" load bootstrap sequences and boot without side-effects (eg, unexpected interrupts)

Loading the RX11 Bootstrap
|
||||
--------------------------
|
||||
|
||||
From the [RT-11 v4.0 Installation Manual (March 1981)](/pubs/dec/pdp11/rt11/), p. E-9:
|
||||
|
||||
The procedure to deposit the RX11 disk bootstrap loader in memory depends on the type of processor you have.
|
||||
If your computer is a PDP-11V/03, PDP-11/03, or LSI-11, see the PDP-11/03 user's manual for instructions.
|
||||
|
||||
1. Set the ENABLE/HALT switch to HALT.
|
||||
|
||||
2. Set the first address, 010000, in the switch register (see Table E-3).
|
||||
|
||||
3. Press the LOAD ADDR switch.
|
||||
|
||||
4. Set the contents for the first address (from Table E-3) in the switch register.
|
||||
|
||||
5. Lift the DEP switch. The computer automatically advances to the next address.
|
||||
|
||||
6. Set the contents for the next address (from Table E-3) in the switch register.
|
||||
|
||||
7. Lift the DEP switch.
|
||||
|
||||
8. Repeat steps 6 and 7 until you have deposited all the instructions.
|
||||
|
||||
Now verify that you deposited the bootstrap program properly.
|
||||
|
||||
1. Set the first address, 001000, in the switch register.
|
||||
|
||||
2. Press the LOAD ADDR switch.
|
||||
|
||||
3. Press the EXAM switch to display the contents of that address in the data register.
|
||||
|
||||
4. Compare the number in the data register with the value for that address in Table E-3.
|
||||
|
||||
5. If the values are the same, press EXAM again to display the contents of the next address.
|
||||
If the values are not the same, repeat the entire procedure for depositing the bootstrap.
|
||||
Verify the contents of all the addresses in this way. If any instruction is incorrect,
|
||||
repeat the entire deposit procedure.
|
||||
|
||||
Once you have correctly deposited the bootstrap in memory, start the computer as follows:
|
||||
|
||||
1. Set the starting address, 001000, in the switch register.
|
||||
|
||||
2. Press the LOAD ADDR switch.
|
||||
|
||||
3. Set the ENABLE/HALT switch to ENABLE.
|
||||
|
||||
4. Press the START switch.

Loading the RX-11 Bootstrap Loader
|
||||
----------------------------------
|
||||
|
||||
Any PDP-11 machine using built-in PCjs Debugger makes it easy to enter the bootstrap code above. Paste
|
||||
the following commands into the Debugger's command buffer:
|
||||
|
||||
ew 1000 005000 012701 177170 105711 001776 012711 000003 005711 001776;
|
||||
ew 1022 100405 105711 100004 116120 000002 000770 000000 005000 000110;
|
||||
r pc 1000
|
||||
|
||||
You can then review (eg, disassemble) the bootstrap code:
|
||||
|
||||
>> u 1000 1044
|
||||
001000: 005000 CLR R0

|

001042: 000110 JMP @R0
|
||||
|
||||
Last but not least, make sure you have successfully loaded an RX01 diskette image into drive DX0. Then execute the
|
||||
bootstrap code with the Debugger's "g" command.
|
||||
|
||||
Of course, if the machine also includes the RX11 Boot control, then all you *really* need to is select an
|
||||
RX01 diskette, click "Load", wait for the diskette image to be successfully loaded (i.e., downloaded) and then click
|
||||
"Boot".
