INTRO(4)	     OpenBSD Programmer's Manual (Zaurus)	      INTRO(4)

     intro - introduction to special files and hardware support

     The manual pages in section 4 describe the special files, related driver
     functions, and networking support available in the system.	 In this part
     of the manual, the SYNOPSIS section of each configurable device gives a
     sample specification for use in constructing a system description for the
     config(8) program.	 The DIAGNOSTICS section lists messages which may
     appear on the console and/or in the system error log /var/log/messages
     due to errors in device operation; see syslogd(8) for more information.

     This section contains both devices which may be configured into the
     system and network related information.  The networking support is
     introduced in netintro(4).

     This section describes the hardware supported on the zaurus platform.
     Software support for these devices comes in two forms.  A hardware device
     may be supported with a character or block device driver, or it may be
     used within the networking subsystem and have a network interface driver.
     Block and character devices are accessed through files in the file system
     of a special type; see mknod(8).  Network interfaces are indirectly
     accessed through the interprocess communication facilities provided by
     the system; see socket(2).

     A hardware device is identified to the system at configuration time and
     the appropriate device or network interface driver is then compiled into
     the system.  When the resultant system is booted, the autoconfiguration
     facilities in the system probe for the device and, if found, enable the
     software support for it.  If a device does not respond at
     autoconfiguration time it is not accessible at any time afterwards.  To
     enable a device which did not autoconfigure, the system will have to be

     The autoconfiguration system is described in autoconf(4).	A list of the
     supported devices is given below.

     The devices listed below are supported in this incarnation of the system.
     Pseudo-devices are not listed.  Not all supported devices are listed.

	   apm(4)	  advanced power management device interface
	   cd(4)	  ATAPI and SCSI CD-ROM driver
	   com(4)	  serial communications interface
	   lcd(4)	  Zaurus LCD display
	   pxadmac(4)	  PXA2x0 DMA controller
	   pxagpio(4)	  PXA2x0 GPIO interface
	   pxaintc(4)	  PXA2x0 interrupt controller
	   pxaip(4)	  PXA2x0 Integrated Peripheral Bus
	   pxammc(4)	  MMC/SD/SDIO controller
	   pxaost(4)	  PXA2x0 OS timer
	   pxapcic(4)	  PXA2x0 PCMCIA interface
	   pxaudc(4)	  PXA27x USB device controller
	   scoop(4)	  Compact Flash and GPIO controller
	   sd(4)	  SCSI disk driver
	   wd(4)	  WD100x compatible hard disk driver
	   wdc(4)	  WD100x compatible hard disk controller driver
	   zaudio(4)	  Zaurus audio device
	   zkbd(4)	  Zaurus keyboard support
	   zrc(4)	  Zaurus remote control support
	   zssp(4)	  SSP for inter-chip communication
	   zts(4)	  Zaurus touchscreen support

     A further list of available devices is contained within the pages
     describing the system buses and controllers.  For example, a PCMCIA
     device would be listed in the pcmcia(4) man page.	The following buses
     and controllers list these devices:

	onewire(4)    1-Wire bus
	pcmcia(4)     introduction to PCMCIA (PC Card) support
	usb(4)	      introduction to Universal Serial Bus support

     autoconf(4), config(8)

     The zaurus intro first appeared in OpenBSD 3.7.
