Section 1. Basic Unit
2.1 STORAGE PROTECT KEY--DISPLAY
For the storage key to
te
displayed, the
M-register must be set to the 2,048 bytes
associated with the CPU storage key.
For
the protect key associated with an MPX
ucw
er ICA UCW to te displayed, the M-register
must be set to the UCW auxiliary storage
address.
Therefore, a manual display of
auxiliary storage rrust be dcne to see the
f
rctect key used ty an
SIC~
a rranual
display of main storage must be done to see
the CPU storage key.
After the manua
1
display, turn the rrode
switch to AIU/EXT position and dial
switches CD to 03 (CPU roode external decode
3).
Pressing the display switch gates the
storage key into byte 1.
The selector channel key can be
displayed
by
using auxiliary storage
address XX88 and following the preceding
display procedure.
'Ibis is possible since
MPX UCWs cannot be used when channel burst
mode is defined.
There are two exceptions to this display
t:rocedure..
The M-register does net have to
be set up to display the effective file
protect key.
This is possible because the
file key is stored in hardware (not STP
local storage).
To display the effective
file protect key, dial 12
in
switch CD and
dial ALU/EXT.
To check the protect key associated with
the integrated 254 0. 1403, er 1052
ucw,
refer to the auxiliary storage map for
module 0 to determine which byte to
display.
During data transfer, the i;:rotect
key is stored with the storage key read
from STP local storage.
2.2 PATCH CARD GENERATICN
This procedure can te used to make a patch
card for entering a rricroprograrr into the
FE
trap area.
The system must have the
System/360 emulator loaded.
Enter the
f cllcwing data into the locations
specified. make the punch ready, set IC to
0058., press the start key.
The replace
Card will punch in EBCDIC format.
This
replace card can be inserted bef cre the end
card of a CSL deck or you can make
up
a
standalone deck in the following manner.
1.
Five card loader
2.
Four cards frcro the 360 emulator CSL
deck for
cs
module addresses 0100,
0140, 0180, OlCO (card nuxr.bers 6, 7, 8,
and 9)
3.
The replace card
4.
The end card, blank in column 3.
If the loading device is on the channel,
use the following.
1.
One- card channel loader
2.
Four cards frcro 360 CSL deck
addresses:
0100~
0140, 0180, 01CO
(card nurrbers 6, 7, 8, and 9).
