Hello,

Me again.  I would like to tell you that my system hang problem was solved by 
changing the motherboard (Asus P/I-P55T2P4).  I think that my VEGA-P54C-IDP
(dual pentium system board) didn't communicate well enough with my aha2940. I
am here to thanks again for those who response and help me.  Thanks.  I am now
can concentrate on my computer graphics project.

cheers

clarence
