see 48.Xr syslogd 8 49for more information. 50.Pp 51This section contains both devices which may be configured into 52the system and network related information. 53The networking support is introduced in 54.Xr netintro 4 . 55.Sh DEVICE SUPPORT 56This section describes the hardware supported by 57.Nx Ns /arc . 58Software support for these devices comes in two forms. 59A hardware device may be supported with a character or block 60.Em device driver , 61or it may be used within the networking subsystem and have a 62.Em network interface driver . 63Block and character devices are accessed through files in the file 64system of a special type; see 65.Xr mknod 8 . 66Network interfaces are indirectly accessed through the interprocess 67communication facilities provided by the system; see 68.Xr socket 2 . 69.Pp 70A hardware device is identified to the system at configuration time 71and the appropriate device or network interface driver is then 72compiled into the system. 73When the resultant system is booted, the autoconfiguration facilities 74in the system probe for the device and, if found, enable the software 75support for it. 76If a device does not respond at autoconfiguration time it is not 77accessible at any time afterwards. 78To enable a device which did not autoconfigure, the 79system must be rebooted. 80.Pp 81The autoconfiguration system is described in 82.Xr autoconf 4 . 83A list of the supported devices is given below. 84.Sh SEE ALSO 85.Xr config 1 , 86.Xr autoconf 4 87.Sh HARDWARE 88.Nx Ns /arc 89supports a variety of systems conforming to the ARC machine 90specification. 91The following systems are supported: 92.Pp 93.Bl -tag -width XXXXXX -offset indent -compact 94.It Acer PICA 95.It DESKstation rPC44 96.It DESKstation Tyne 97.It MIPS Magnum 4000 98.It NEC Express 5800/230 PCI R4K 99.It NEC Express 5800/240 EISA R4K 100.It NEC Express RISCserver 101.It NEC ImageRISCstation 102.It NEC RISCserver 2200 103.It NEC RISCstation 2200 EISA 104.It NEC RISCstation 2200 PCI 105.It NEC RISCstation 2250 106.El 107.Sh LIST OF DEVICES 108The devices listed below are supported in this incarnation of the 109system. 110Devices are indicated by their functional interface. 111Not all supported devices are listed. 112.Pp 113.Bl -tag -width jazzisabr -offset indent -compact 114.It arcsisabr 115DESKstation rPC44 ISA host bridge 116.It jazzio 117Jazz internal bus host bridge 118.It jazzisabr 119Jazz ISA/EISA bus bridge 120.It necpb 121NEC RISCstation PCI host bridge 122.It tyneisabr 123DESKstation Tyne ISA host bridge 124.El 125.Pp 126The following devices on the Jazz internal bus are supported. 127.Pp 128.Bl -tag -width mcclock -offset indent -compact 129.It asc 130NCR 53c9x-based SCSI interface 131.It com 132NS16550-based serial communications interface 133.It fdc 134Floppy disk controller 135.It lpt 136Parallel port 137.It mcclock 138DS1287 real-time clock 139.It oosiop 140Symbios/NCR 53c700-based SCSI interface 141.It osiop 142Symbios/NCR 53c710-based SCSI interface 143.It pckbc 144PC keyboard controller 145.It sn 146SONIC Ethernet 147.It timer 148Interval timer 149.It vga 150VGA graphics 151.El 152.Pp 153PCI devices are supported through the 154.Xr pci 4 155bus and associated device drivers. 156.Pp 157ISA devices are supported through the 158.Xr isa 4 159bus and associated device drivers. 160.Pp 161.\"EISA devices are supported through the 162.\".Xr eisa 4 163.\"bus and associated device drivers. 164.\".Pp 165Console devices using ISA, Jazzio, or PCI video adaptors and standard AT 166or PS/2 keyboards are supported by the machine independent 167.Xr wscons 4 168console driver. 169.Sh UNSUPPORTED DEVICES 170The following devices are not supported, due to unavailability of 171either documentation or sample hardware: 172.Pp 173.Bl -tag -width XXXXXX -offset indent -compact 174.It AD1848 audio on Jazzio 175.It EISA devices 176.It VXL framebuffer on MIPS Magnum and RISCstation 2200 EISA 177.El 178.Sh HISTORY 179This 180.Tn arc 181.Nm intro 182appeared in 183.Nx 2.0 . 184.Sh BUGS 185DESKstation rPC44 and Tyne support is currently broken. 186
