Description
Enables system for I/O interrupts.
Builds real control blocks for scratch tape. Sets up device type for disk containing the starter system. Starter system entry point called by DMKSIV. Identifies the system console. Handles the I/O for display terminals.
Displays starter system header message.
Builds all the real control blocks necessary.
Builds the real control blocks for the punch.
Builds the real control blocks fer the tape drive containing the
PID (Program Information tepartment) distributien taFe. Builds the real control blocks for the printer.
Builds the real control blocks fer the reader,.
Initiates writes to and reads fro. the console to determine the
device address.
Initiates writes to and reads from the console to determine the
device type.
Writes to and reads from the console. The REI WRITE routine is
called by both the REIDAttR and REIDTYPE routines.
Asks the operator if he wants to redefine the system. Finds or builds the necessary real control blocks.
Issues the Start I/O (SIO). Builds the real control blocks fer the disk that contains the system residence volume. Checks for a valid CPU model. Asks the operator if the configuration just defined is the one he
