Hatari - tos.c
This file is distributed under the GNU General Public License, version 2
or at your option any later version. Read the file gpl.txt for details.
Load TOS image file into ST memory, fix/setup for emulator.
The Atari ST TOS needs to be patched to help with emulation. Eg, it
references the MMU chip to set memory size. This is patched to the
sizes we need without the complicated emulation of hardware which
is not needed (as yet). We also patch DMA devices and Hard Drives.
NOTE: TOS versions 1.06 and 1.62 were not designed for use on a
real STfm. These were for the STe machine ONLY. They access the
DMA/Microwire addresses on boot-up which (correctly) cause a
bus-error on Hatari as they would in a real STfm. If a user tries
to select any of these images we bring up an error. */
