A hardware 68device may be supported with a character or block 69.Em device driver , 70or it may be used within the networking subsystem and have a 71.Em network interface driver . 72Block and character devices are accessed through files in the file 73system of a special type; see 74.Xr mknod 8 . 75Network interfaces are indirectly accessed through the interprocess 76communication facilities provided by the system; see 77.Xr socket 2 . 78.Pp 79A hardware device is identified to the system at configuration time 80and the appropriate device or network interface driver is then compiled 81into the system. When the resultant system is booted, the 82autoconfiguration facilities in the system probe for the device 83and, if found, enable the software support for it. 84If a device does not respond at autoconfiguration 85time it is not accessible at any time afterwards. 86To enable a device which did not autoconfigure, 87the system must be rebooted. 88.Pp 89The autoconfiguration system is described in 90.Xr autoconf 4 . 91A list of the supported devices is given below. 92.Sh SEE ALSO 93.Xr autoconf 4 , 94.Xr bwtwo 4 , 95.Xr cd 4 , 96.Xr cgeight 4 , 97.Xr cgfour 4 , 98.Xr cgfourteen 4 , 99.Xr cgsix 4 , 100.Xr cgthree 4 , 101.Xr cgtwo 4 , 102.Xr ch 4 , 103.Xr fd 4 , 104.Xr kbd 4 , 105.Xr le 4 , 106.Xr magma 4 , 107.Xr mem 4 , 108.Xr ms 4 , 109.Xr openprom 4 , 110.Xr scsi 4 , 111.Xr sd 4 , 112.Xr ss 4 , 113.Xr st 4 , 114.Xr tcx 4 , 115.Xr uk 4 , 116.Xr config 8 117.Sh SUPPORTED SYSTEMS 118The following Sun SPARC system architectures and models are supported: 119.Bl -tag -width speaker 120.It sun4 121first generation SPARC systems on VMEbus: 122.br 123Sun 4/100 series (14.28 MHz) 124.br 125Sun 4/200 series (16.67 MHz) 126.br 127Sun 4/300 series (25 MHz) 128.It sun4c 129desktop SPARC systems with Sbus: 130.br 131SPARCstation 1 (20 MHz) 132.br 133SPARCstation 1+ (25 MHz) 134.br 135SPARCstation 2 (40 MHz) 136.br 137SPARCstation SLC (20 MHz) 138.br 139SPARCstation ELC (33 MHz) 140.br 141SPARCstation IPC (25 MHz) 142.br 143SPARCstation IPX (40 MHz). 144.It sun4m 145desktop SPARC systems with Mbus for CPUs, and Sbus: 146.br 147SPARCclassic (50 MHz microSPARC I) 148.br 149SPARC LX (50 MHz microSPARC I) 150.br 151SPARCstation 4 (70 MHz microSPARC II) 152.br 153SPARCstation 5 (70, 85, 110 MHz microSPARC II) 154.br 155SPARCstation 5 (170 MHz TurboSPARC) 156.br 157SPARCstation 10M (36 MHz SuperSPARC I) 158.br 159SPARCstation 20M (50 MHz SuperSPARC I) 160.br 161SPARCstation 10 (Mbus modules) 162.br 163SPARCstation 20 (Mbus modules) 164.El 165.Pp 166The SPARCstation 2 and IPX can be upgraded with a Weitek PowerUP CPU 167that is clock-doubled (i.e. internally it runs at 80 MHz). 168.Nx 169supports this configuration. 170.Pp 171Hardware level clones of these systems from other manufacturers 172will likely work (e.g. Xerox, Tatung, Axil, Cycle); 173other systems which have a SPARC CPU but do not 174use Sun's hardware architecture (e.g. Solbourne) will likely not work. 175.Pp 176The sun4m architecture with Mbus modules for the CPUs is supported 177with the following modules with only one CPU: 178.Bl -tag -width speaker 179.It SM41 18040 MHz SuperSPARC I with 1MB SuperCACHE 181.It SM51 18250 MHz SuperSPARC I with 1MB SuperCACHE 183.It SM61 18460 MHz SuperSPARC I with 1MB SuperCACHE 185.It SM71 18675 MHz SuperSPARC II with 1MB SuperCACHE 187.It SM81 18885 MHz SuperSPARC II with 1MB SuperCACHE 189.It HS11 190100 MHz Ross Technology hyperSPARC 191.It HS21 192125 MHz Ross Technology hyperSPARC 193.It M151 194150 MHz Ross Technology hyperSPARC 195.El 196.Pp 197This list is not exhaustive; 198.Nx 199is continuously being improved, and may well run on Mbus CPU modules 200not listed here. 201.Pp 202There is also some support for Sun 203.Tn JavaStation 204computers based on the microSPARC CPU. 205.Pp 206.Nx 207does not yet properly support multiprocessor systems, 208but will run on one processor of a multiprocessor system. 209.Pp 210The Sun 4/400 series, and sun4d (SPARCcenter 1000, 1000E, and 2112000) are not supported. 212.Pp 213The sun4u (UltraSPARC 64-bit) architectures are supported by 214.Nx Ns Tn /sparc64 . 215.Sh LIST OF DEVICES 216The devices listed below are supported in this incarnation of 217the system.
