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 intro 4 , 94.Xr autoconf 4 , 95.Xr config 8 . 96.Sh SUPPORTED SYSTEMS 97The following systems are supported: 98.Bl -tag -width speaker -offset indent -compact 99.It Decstation 2100 and 3100 100also known as "pmax". The 2100 and 3100 differ only in CPU clock speed. 101.It Decstation 5000/200 102also known as "3MAX". The 5000/200 has a 25MHz r3000 and is the 103first-generation TurboChannel platform. 104.It Decstation 5000/1xx 105also known as "3MIN" or "kmin". The 5000/1xx comes in 20MHz, 25Mhz, 106and 33MHz versions and is numbered appropriately. 107Two 12.5MHz 108turbochannel slots are provided. 109.It Decstation 5000/2x 110also known as "Personal DECstation" or "MAXINE". The 5000/xx comes in 11120MHz and 25Mhz variants. A baseboard 1024x786 framebuffer 112Two 12.5MHz turbochannel slots and are provided. 113.It Decstation 5000/240 and DecSystem 5900 114aslso known as "3MAXPLUS". These systems have a 40MHz r3400 115CPU and three 25MHz TurboChannel slots. 116The 5900 is an expanded-cabinet version of the 5000/240. 117.El 118.Pp 119Turbochannel systems (except the 5000/200) can be upgraded to an R4000 120or r4400 cpu by upgrading the cpu daughterboard. These systems (5000/150, 5000/50, 121and 5000/260) are not supported. 122The DECstation 5100 and the Qbus-based Decsystem 5400 and 5500 are not supported. 123The multi-processor XMI-bus Decsystem 5800 is not supported. 124.Sh LIST OF DEVICES 125The devices listed below are supported in this incarnation of 126the system.
