And the additional driver can be 60attached to the bus. 61.Pp 62Up to 63 devices, including the host itself, can be attached to 63a firewire bus. The root node is dynamically assigned with PHY 64device function. Also, the other firewire bus specific parameters 65e.g. node id, cycle master, isochronous resource manager and bus 66manager, are dynamically assigned, after bus rest is initiated. 67On firewire bus, every device is identified with EUI 64 address. 68 69.Pp 70.El 71.Sh SEE ALSO 72.Xr fwohci 4 , 73.Xr pci 4 , 74.Xr sbp 4 , 75.Sh HISTORY 76The 77.Nm 78driver first appeared in 79.Fx 5.0 . 80.Sh AUTHORS 81The 82.Nm 83driver was written by 84.An Katsushi Kobayashi 85and 86.An Hidetoshi Shimokawa 87for the 88.Nx 89project. 90
