Hi Adam, AT the beggining i want to sorry about my poor english. I had a short look at your fbd assembly tutorial. I'm have a such problem useing IN, OUT commands. In my case i want to "speak" with cmos by port 70 and 71. We both know that fbsd as same as linux works in safe mode. So we need a permission to use each port. In linux it's a system call sys_ioperm (http://www.die.net/doc/linux/man/man2/ioperm.2.html). How to ask FreeBSD to allow us to use those ports ? And then we could simply do: mov al, 0 out 70h, al nop nop nop nop in al, 71h Do you haveny any idea ? Best regards, Jan Opacki.
