HIMEM.SYS is meant to prevent that. So you shouldn't find that strange behaviour when himem is loaded.

Wish it was true but it isn't. Hmm. I would like to have Rebel play the same moves either autoplay tournament or normal tournament.

I was surprised then, now I understand better. But in the end >the Rebel case has to be proven as I don't have the hard evidence yet. Except for your very strange "game" and your arguments I haven't seen much strange (no wonder, I have no Rebel10-autoplayer-version... ;-)) within Rebel but I can follow your memory problem. And at the moment it seems to me that all (DOS-)programs not using himem should suffer because of that memory sharing problem with that TSR program called autoplayer...DID any of the earlier versions of Hiarcs or MCP? btw why doesn't harm a mouse driver Rebels abilities, it is also TSR. >>>All in all we need some time to figure this all out and in order to release >>>an auto232 version that plays chess as the normal Rebel10 does and >>>is not handicapped by external drivers. >>>Ed Schroder > >>Did you check this phenomenon also with Rebel9 or 8? > >At that time the thought never crossed my mind. I admit I am a bit confused. Do you say there were no such phenomenons with Rebel8/9 but now there is in Rebel10 or do you mean you haven't recognized OBVIOUS things in the autoplayer-games of Rebel8/9? >>BTW this seems to be another reason to port Rebel to Windows. ;-) > >Harald, this is cruel :-) Maybe. :-) Honestly Rebel, Hiarcs and MChessPro are the only reasons why I use Win95A to be able to boot pure DOS6.22...it would be much easier not to have the necessity to boot up only for one damn program. ;-) And also it would be better to have it run in NT... OK, Fritz took some time to be converted to Windows, Genius much more, but Shredder and Nimzo didn't, e.g. :-) The lobby of DOS-users is getting smaller and smaller... ;-)
