Interesting!
(What is an IMF?)
IMF = internal machine fix
The 5100/5110 had a mechanism to load resident binary routines into memory
in order to patch ROS (=ROM) routines or to add a driver (e.g. the
Plot feature). Basically, you load a program that then relocates the
resident part to the end of free memory, patches some entry points in RWS
(=RAM) and adjusts the end-of-memory value.
