; Filename:  RMXXX.Y.TEXT, XXX = ROM VERSION # (e.g., 200 for 2.00)
;			     Y = E (equates)
;			       = K (kernel tests)
;			       = S (secondary tests)
;			       = B (bootstrap code)
;			       = M (monitor code)
;			       = G (graphics, icon and message display)
;
; Function:  Initializes LISA system for use and performs preliminary
;	     diagnostic checks.	 If all tests pass, the system then
;	     does a keyboard scan to check for user input.  If any key
;	     is hit other than caps lock or the mouse button,
;	     a menu is displayed on the screen showing the available
;	     boot devices.  If a valid COMMAND key sequence is detected,
;	     a boot from an alternate device is attempted (see below).
;	     If no keyboard input is detected, the system first checks
;	     parameter memory for a valid boot device and, if none, defaults
;	     to booting from a Profile attached to the builtin parallel port
;	     for Lisa 1 systems.
;
;	     For Lisa 2 systems, a check is first made to verify a disk
;	     (internal or external) is connected before defaulting to the
;	     hard disk boot.  If no disk is detected, the system defaults
;	     to booting from the floppy drive.
;
;
;
; Inputs:    Checks for keyboard input from the user.  Currently, the following
;	     key sequences are honored if input after the system "clicks" the
;	     speaker (CMD refers to the Apple key on the keyboard):
;
;	        CMD/1 - boot from Twiggy drive #1 or integral hard disk
;	        CMD/2 - boot from Twiggy drive #2 or SONY drive
;	        CMD/3 - boot from Profile attached to parallel port or integral hard disk
;	        CMD/4 - boot from I/O slot #1, port 1
;	        CMD/5 - boot from I/O slot #1, port 2
;	        CMD/6 - boot from I/O slot #2, port 1
;	        CMD/7 - boot from I/O slot #2, port 2
;	        CMD/8 - boot from I/O slot #3, port 1
;	        CMD/9 - boot from I/O slot #3, port 2
;	        CMD/ENTER (on key pad) - abort boot, branch to ROM monitor
;	        CMD/SHIFT/P - abort boot, do power cycling
;
;  OUTPUTS:  Saves various results and contents of system registers in memory
;	     for examination by system programs or with the ROM monitor.
