02 Read error.
Cause: A read error occurred on the IPL device (either
disk or diskette) during execution.
Action: If you were using a diskette to IPL, try again
with a backup diskette. If you were using the disk to
IPL, install the Virtual Resource Manager (VRM) again,
then IPL the system. If error condition still exists, go to
IB M R T Problem Determination Guide
procedures for problem determination. If no problem is
found before the "Diagnostic Selection" menu is
displayed, run "System Checkout."
Not enough memory to load a module.
03
Cause: There was not enough free space in memory to
load a module. If you have changed the VRM minidisk
by adding code, then it is possible that an added routine
is writing over the internal data fields of the loadlist
processor.
If the VRM minidisk has not been changed, there may
not be enough contiguous memory to load the system.
Action: If the VRM minidisk has been changed, install
the VRM again. If error condition still exists, go to
R T Problem Determination Guide
procedures for problem determination. If no problem is
found before the "Diagnostic Selection" menu is
displayed, run "System Checkout."
Not enough space for the Define Device Area
04
(DDA).
Cause: There was not enough memory to allocate space
for the DDA. See error 03 for possible causes and
actions.
