I could test on a real TT later if you want. But I'm already very
certain that $42e is supposed to only contain ST-RAM:
phystop LONG 0x42e Pointer to the first byte above the physical
end of the ST-compatible RAM region (physical top of ST-compatible RAM)
The end of TT-RAM is in...
ramtop LONG 0x5a4 Pointer to the end of the Fast-RAM in Atari TT
(not officially documented).
<http://toshyp.atari.org/en/003004.html>
I have those doc too, and I agree 42e should certainly contain the end
of ST RAM.
But since it's the content of $42e that directly evaluate the entry to
override in the MMU tables, I was thinking at the same time I wrote an
email that it could be an option to check.
I think the problem here is that Hatari allows you to run with 14 MB of
*ST*-RAM and FIX24.PRG does not take this possibility into account. Real
TTs -- at least with Atari's RAM boards -- could have 10 MB ST-RAM maximum.
Yes, that's the other option I was considering, that fix24.prg doesn't
support so much ST RAM.
If I run with less ST RAM (10 MB), then fix24 is working, there's no crash.
Uwe, what working memory config did you use on your TT to be sure we
test the same under Hatari ?
