A hardware 73device may be supported with a character or block 74.Em device driver , 75or it may be used within the networking subsystem and have a 76.Em network interface driver . 77Block and character devices are accessed through files in the file 78system of a special type; see 79.Xr mknod 8 . 80Network interfaces are indirectly accessed through the interprocess 81communication facilities provided by the system; see 82.Xr socket 2 . 83.Pp 84A hardware device is identified to the system at configuration time 85and the appropriate device or network interface driver is then compiled 86into the system. When the resultant system is booted, the 87autoconfiguration facilities in the system probe for the device 88and, if found, enable the software support for it. 89If a device does not respond at autoconfiguration 90time it is not accessible at any time afterwards. 91To enable a device which did not autoconfigure, 92the system will have to be rebooted. 93.Pp 94The autoconfiguration system is described in 95.Xr autoconf 4 . 96A list of the supported devices is given below. 97.Sh SEE ALSO 98.Xr intro 4 , 99.Xr autoconf 4 , 100.Xr config 8 . 101.Sh LIST OF DEVICES 102The devices listed below are supported in this incarnation of 103the system. 104Devices are indicated by their functional interface. 105Not all supported devices are listed. 106.Bl -tag -width "okiadpcm" -compact -offset indent 107.It Em spc 108Sharp genuin MB89352 SCSI host adaptor 109.It Em mha 110MK-HA1 Mankai-Seisakusho Mach-2 SCSI host adaptor 111.It Em ed 112Neptune-X Ethernet interface 113.It Em fdc 114Built-in floppy disk controller device 115.It Em fd 116Floppy disk device 117.It Em grf 118Built-in frame buffer 119.It Em kmem 120kernel virtual memory 121.It Em ite 122x68k Internal Terminal Emulator 123.It Em mem 124physical memory 125.It Em par 126Centronics printer interface 127.It Em com 128NS16450 serial interface 129.It Em zs 130Z8530 built-in serial interface 131.\".It Em okiadpcm 132.\"Oki MSM6258V AD-PCM 133.It Em kbd 134x68k Keyboard device 135.It Em mouse 136x68k mouse / trackball 137.It Em bell 138The keyboard bell emulator 139.It Em pow 140The power switch 141.El 142.Sh HISTORY 143The 144.Tn x68k 145.Nm intro 146man page first appeared in 147.Nx 1.3 . 148
