Ok, sorry for a top post. NetBSD was installed into that usb key earlier (and it booted succesfully). I formated it and installed OpenBSD instead. At boot I see information about CPU and computer hangs at this point. Hm, I can try to rewrite mbr with other boot loader. I'll post the results later (after 8-10 hours). Regards, Andrius V
