Go up one level in this thread


I created the bitbases. Bitbases didn't influence the nodes alot, but the search
time decreased. It finds now the mate in 18 in under 6 mins. (See below)
I also increased the hashtable to 130M, which in contrast reduced the nodes that
have to be calculated (which makes sense actually). :)
What HT size do you use?

Lilo and Grub are not USB aware, the USB support is provided by the BIOS and
that unless your BIOS supports a USB keyboard, you may not be able to select a
non-default boot image using the USB keyboard.

The option in the BIOS that hast to be enbled is called 'usb legacy support'. It
may help to update BIOS.
