Re: [hatari-devel] Hatari freezing when running FIX24.PRG

[ Thread Index | Date Index | More lists.tuxfamily.org/hatari-devel Archives ] 

Hi,

Just checking what the copy of FIX24 I provided actually does ;-). As
already mentioned it's an updated version of the one that was published
in ST Computer 4/91, and it does not yet try to re-map memory from the
TT-RAM to the ST-RAM area.
And yes, you are right, there is another program (attached) that makes
this memory usable. I completely forgot about this one, even though it
was actually published together with an update to FIX24 one month later.
For those who know German and are interested in how the PMMU works, those
two articles may be interesing in this context. I'm currently re-learning
things I completely forgot :).

Note that I cannot test this on a real TT right now, but it is safe to
assume that both programs were working on real TTs. But as Christian
already pointed out, there might be problems with more than 10 MB of
ST-RAM.
While trying to run more tests with Hatari I just stumbled upon a problem:
With only 4 MB ST-RAM configured NVDI does not install on Hatari. First
I thought this was another NVDI issue, but then I noticed that it looks
as if no AUTO order program is executed at all when I configure 4 MB of
ST-RAM. For reference I attached my configuration file once again. With
this configuration Hatari launches everything in my AUTO folder on C,
but when I reconfigure (after pressing F12) Hatari to only provide 4 MB
ST-RAM and then reboot, no AUTO folder programs are executed anymore.

Best regards

Uwe
