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 LIST OF DEVICES 98The devices listed below are supported in this incarnation of 99the system. 100Devices are indicated by their functional interface. 101Not all supported devices are listed. 102.Bl -tag -width "xxxxxx" -compact -offset indent 103.It Em clmpcc 104Cirrus Logic CD2401 four channel Communications controller 105.It Em clock 106Hardware counter/timer clock driver 107.It Em ie 108.Tn Intel 10982596-based Ethernet interface 110.It Em kmem 111kernel virtual memory 112.It Em le 113.Tn AMD 114Lance-based Ethernet interface 115.It Em lpt 116Onboard parallel printer interface 117.It Em mem 118physical memory 119.It Em mcchip 120MVME162 and MVME172 MCChip (similar to PCCchip2) 121.It Em ncrsc 122.Tn NCR 12353c710 SCSI I/O Processor 124.It Em pcc 125MVME147 PCC Chip 126.It Em pcctwo 127MVME167 and MVME177 PCCchip2 128.It Em vmepcc 129MVME147 VMEbus interface chip 130.It Em vmetwo 131MVME1[67]x Enhanced VMEbus interface chip 132.It Em wdsc 133WD33c93 SCSI Bus Interface Controller 134.It Em zsc 135.Tn Zilog 136Z8530 Dual-port Serial Interface on MVME147 and MVME162 137.El 138.Sh SEE ALSO 139.Xr autoconf 4 , 140.Xr config 8 141.Sh HISTORY 142The 143.Tn mvme68k 144.Nm intro 145man page first appeared in 146.Nx 1.5 . 147
