System Startup, Configuration, and Shutdown Reference Manual

Chapter 3  System Startup Functions 

The initial system loader (ISL) provides a command-driven user interface
for accessing boot utilities or issuing ISL commands to display or change
system startup functions.  When the system is booted from tape (tape
boots), processor-dependent code (PDC) directly loads the ISL. When the
system is booted from disk (disk boots), PDC and input/output-dependent
code (IODC) boot the utility MMSAVE, which in turn boots ISL.

When loaded, the ISL displays its revision number and prompts for input:

     ISL Revision A.00.07  September 12, 1990

     ISL>


NOTE  The prompt changes to ISL>, indicating the ISL is active.
