I used 40M of HT, and the default egtb_cache of 2M. The hardisk was working like
crazy. I don't really know what bitbases is, but I left all the other options at
the default. I only have 3,4,5 men TB.

Was just wondering, because until the mate announcement, your version had to
look only at half the nodes for the same depth. So I thought maybe you improved
it a lot.

thanks
Andy

PS: in some BIOS there is an option 'use USB keyboard' that you have to enable
first.
