If this 40S you were doing a scratch install on was not the system you
created the SAVSYS backup from, you  should have selected 'N' for
"Enable automatic configuration".
If you then get SRC A9002000 you refer to the specific section in the
"Backup & Recovery - Basic" manual that addresses specifically how to
recover from this situation.

However, did you say that the system hung with a blank display and
A9002000 displayed, which would imply you would be unable to follow the
instructions in the manual to create the tape device/controller to
continue the restore ?
