55see 56.Xr syslogd 8 57for more information. 58.Pp 59This section contains both devices 60which may be configured into the system 61and network related information. 62The networking support is introduced in 63.Xr netintro 4 . 64.Sh DEVICE SUPPORT 65This section describes the hardware supported on the SPARC 66platform. 67Software support for these devices comes in two forms. 68A hardware device 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. 82When the resultant system is booted, the 83autoconfiguration facilities in the system probe for the device 84and, if found, enable the software support for it. 85If a device does not respond at autoconfiguration 86time it is not accessible at any time afterwards. 87To enable a device which did not autoconfigure, 88the system must be rebooted. 89.Pp 90The autoconfiguration system is described in 91.Xr sparc/autoconf 4 . 92A list of the supported devices is given below. 93.Sh SEE ALSO 94.Xr config 1 , 95.Xr cd 4 , 96.Xr ch 4 , 97.Xr le 4 , 98.Xr scsi 4 , 99.Xr sd 4 , 100.Xr sparc/autoconf 4 , 101.Xr sparc/bwtwo 4 , 102.Xr sparc/cgeight 4 , 103.Xr sparc/cgfour 4 , 104.Xr sparc/cgfourteen 4 , 105.Xr sparc/cgsix 4 , 106.Xr sparc/cgthree 4 , 107.Xr sparc/cgtwo 4 , 108.Xr sparc/fd 4 , 109.Xr sparc/kbd 4 , 110.Xr sparc/magma 4 , 111.Xr sparc/mem 4 , 112.Xr sparc/ms 4 , 113.Xr sparc/openprom 4 , 114.Xr sparc/tcx 4 , 115.Xr ss 4 , 116.Xr st 4 , 117.Xr uk 4 118.Sh SUPPORTED SYSTEMS 119The following Sun SPARC system architectures and models are supported: 120.Bl -tag -width speaker 121.It sun4 122first generation SPARC systems on VMEbus: 123.br 124Sun 4/100 series (14.28 MHz) 125.br 126Sun 4/200 series (16.67 MHz) 127.br 128Sun 4/300 series (25 MHz) 129.It sun4c 130desktop SPARC systems with Sbus: 131.br 132SPARCstation 1 (20 MHz) 133.br 134SPARCstation 1+ (25 MHz) 135.br 136SPARCstation 2 (40 MHz) 137.br 138SPARCstation SLC (20 MHz) 139.br 140SPARCstation ELC (33 MHz) 141.br 142SPARCstation IPC (25 MHz) 143.br 144SPARCstation IPX (40 MHz). 145.It sun4m 146desktop SPARC systems with Mbus for CPUs, and Sbus: 147.br 148SPARCclassic (50 MHz microSPARC I) 149.br 150SPARCstation LX (50 MHz microSPARC I) 151.br 152SPARCstation 4 (70 MHz microSPARC II) 153.br 154SPARCstation 5 (70, 85, 110 MHz microSPARC II) 155.br 156SPARCstation 5 (170 MHz TurboSPARC) 157.br 158SPARCstation 10M (36 MHz SuperSPARC I) 159.br 160SPARCstation 20M (50 MHz SuperSPARC I) 161.br 162SPARCstation 10 (Mbus modules) 163.br 164SPARCstation 20 (Mbus modules) 165.El 166.Pp 167The SPARCstation 2 and IPX can be upgraded with a Weitek PowerUP CPU 168that is clock-doubled (i.e. internally it runs at 80 MHz). 169.Nx 170supports this configuration. 171.Pp 172Hardware level clones of these systems from other manufacturers 173will likely work (e.g. Xerox, Tatung, Axil, Cycle); 174other systems which have a SPARC CPU but do not 175use Sun's hardware architecture (e.g. Solbourne) will likely not work. 176.Pp 177The sun4m architecture with Mbus modules for the CPUs is supported 178with the following modules with only one CPU: 179.Bl -tag -width speaker 180.It SM41 18140 MHz SuperSPARC I with 1MB SuperCACHE 182.It SM51 18350 MHz SuperSPARC I with 1MB SuperCACHE 184.It SM61 18560 MHz SuperSPARC I with 1MB SuperCACHE 186.It SM71 18775 MHz SuperSPARC II with 1MB SuperCACHE 188.It SM81 18985 MHz SuperSPARC II with 1MB SuperCACHE 190.It HS11 191100 MHz Ross Technology hyperSPARC 192.It HS21 193125 MHz Ross Technology hyperSPARC 194.It M151 195150 MHz Ross Technology hyperSPARC 196.El 197.Pp 198This list is not exhaustive;
