An FPU is not required as the 76default kernels include FP-emulation support. 77.It Hades 78A standard Hades with either an 040 or 060 processor and at least 8 Mb of RAM. 79.El 80.\" 81.\" 82.\" 83.Sh DEVICE SUPPORT 84This section describes the hardware supported on the atari 85(atari-clone) platform. 86Software support for these devices comes in two forms. A hardware 87device may be supported with a character or block 88.Em device driver , 89or it may be used within the networking subsystem and have a 90.Em network interface driver . 91Block and character devices are accessed through files in the file 92system of a special type; see 93.Xr mknod 8 . 94Network interfaces are indirectly accessed through the interprocess 95communication facilities provided by the system; see 96.Xr socket 2 . 97.Pp 98A hardware device is identified to the system at configuration time 99and the appropriate device or network interface driver is then compiled 100into the system. When the resultant system is booted, the 101autoconfiguration facilities in the system probe for the device 102and, if found, enable the software support for it. 103If a device does not respond at autoconfiguration 104time it is not accessible at any time afterwards. 105To enable a device which did not autoconfigure, 106the system must be rebooted. 107.Pp 108The autoconfiguration system is described in 109.Xr autoconf 4 . 110A list of the supported devices is given below. 111.Sh LIST OF DEVICES 112The devices listed below are supported in this incarnation of 113the system.
