About setup FreeBSD 5.1 RELEASE to Sony notebook PCG-R505GCK

[toor]

When I begin setup I see next message:
eisa0: <EISA bus> on motherboard
eisa0: unknown card B at H0000 (0x08080000) at slot 1
Fatal trap 9: general protection fault while in kernel 
mode

trap number         = 9

What must I do to setup freeBSD to my notebook.
