1. TB Bug should be fixed

2. New completely random book (plays all openings now).

I'm getting an immediate illegal instruction with the new zappa. The last one before this worked properly. I'm using Win 98 on an AthlonXP.

Hi,
the new Zappa installed as Winboard engine under Arena doesn't work. The old one worked as long as tbcache was different from 8M.
Regards Dieter

unknown software exception (0xc000001e) here on P3 and Win2000.

I suck

I forgot to save my old fix!

I'll email Volker a new version ASAP.

Update of the update received and uploaded.

BTW: it works here!

Volker

Would someone mind playing around with the tablebases and seeing if that bug is solved now? (and preferably posting a log or two).

anthony

Same bug, but the logfile is somewhat different from the previous version. It shows that the tbcache setting is out of range instead of resetting it to 0

Using position from Martin Baumung bellow (Bug in Zapa ? thread)

Hello
This update do not work at my PC with Intel Celeron & Windows 98. Open at Winboard but do not move. Previous version plays OK in this PC with incremental time.
In another PC with Intel Pentium III plays OK.
Cheers,
Pablo

Hi Anthony,
this is made with uci engine 03.03.2005 under Chessbase with normal chessbase
settings (chssbase.ini with
[Tablebase]
Path=E:\Tbs
CacheSizeKB=16384
The tbcache is not correct initiated and the engine announces again a mate in 2.
I think, its uci convention to set tb cache in kb ??
Werner
