Savagedly ripped for Paranoid's great STe guide :-
! The Mega STE has a register to control speed and cache
status:
$FFFF8E21 - - - - - - X X
Bit 0 controls the clockspeed (0 = 8 MHz, 1 = 16 MHz),
the upper bit controls the cache (0 = Cache off, 1 = cache on).
Some docs say that all upper 15 bits of $FFFF8E20 need to
be set to "1" to turn the cache on.
Writing to this register in anything but a Mega STE will
most probably lead to a crash, so be sure to check the
Cookie Jar for _MCH to estimate wether this is a Mega STE
or not (Upper word is 1 for STE, lower word is 0x0010 for
Mega STE, 0x0000 for anything else).
