Yes, I know such bootblocks. Often you have a menu there to select PAL/NTSC mode or turn off FAST memory. I didn't check such a bootcode yet, but I guess FAST memory is turned off like the first code I posted. As this routine is called before any CLI window is opened and the bootroutine is a main routine, there can't be much other routines releasing their allocated FAST memory after FAST memory was turned off.
