ISL Summary

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.00.43 Apr 12, 2000ISL>




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