thanks guys,

i understand another solution is GPT partitioning. but i prefer to have
more partitions in traditional freebsd (with MBR table i think). using GPT
is the last solution for me.

i should create more than 8 partitions with gpart command (flag n which
identifies entries) but i have errors when using it. is there any special
option which should be included in kernel in order to use gpart with flag
n? any one test it before?

thanks in advance,
