Command Descriptions
Auto Restart
The
AUTO RESTART (AR)
command allows the System Operator to retry the Power Fail Auto Restart
capability if the Auto Restart was not successful because a disc was down or broken. To initiate an Auto
Restart, the cause for the Auto Restart failure must be corrected, and then the System Operator may
attempt an Auto Restart. Auto Restart should be successful as long as the memory has been powered, the
Auto Restart flag in memory location 0.0358 (hex) is AAAA (hex), and the data in memory on the disc is
uncorrupted.
Following the Power-on CPU test, an abbreviated version of the memory test is executed to find the size
of memory if the Auto Restart flag at $0.0358 is set to $AAAA. Upon successful execution of this test,
all of the I/O cards are tested and communication is established with the System Console. When these
steps have completed, execution is transferred to the Auto Restart entry $ 500 I in the Loader code
module. The WCS boot cuie is executed with the Auto Restart flag and LOAD/Start flags with the start
device set into register file location $EF.
If the Auto Restart should fail because the disc was not ready, up to 4 retries will be made. If the retries
are not successful, return will
be
to the Maintenance Mode
"H
fo r
he 1 p-
>" prompt. The System
Operator may type
AR
for up to 5 retries when the disc is made ready.
The correct syntax for this command is:
AR
Coldstart
The COLDSTART command loads the system microcode and software from the default tape unit and allows
the System Operator to perform the COLDSTART operation for MPE or run
nus.
Auto cold/oad can be
run without intervention by the System Operator.
COLDSTART
differs from
LOAD
in the following ways:
• No
channel
or
device
parameters are allowed.
• The default LOAD device always used.
• No opportunity is given to change the software configuration (no INITIAL dialogue\'
The correct syntax for this command is:
