NAME

prtconf − print system configuration

SPARC SYNOPSIS

/usr/sbin/prtconf [ −F ] [ −p ] [ −P ] [ −v ] [ −V ] [ −D ]

x86 SYNOPSIS

/usr/sbin/prtconf [ −p ] [ −P ] [ −v ] [ −V ] [ −D ]

DESCRIPTION

The prtconf command prints the system configuration information.  The output includes the total amount of memory, and the configuration of system peripherals formatted as a device tree. 

OPTIONS

−P Include information about pseudo devices.  By default, information regarding pseudo devices is omitted. 

−v Specifies verbose mode. 

−F (SPARC only). Return the device pathname of the console frame buffer, if one exists.  If there is no frame buffer, prtconf returns a non-zero exit code.  This flag overrides all others, and returns only the name of the console, frame buffer device or a non-zero exit code.  For example, if the console frame buffer on a SPARCstation 1 is cgthree in SBus slot #3, the command returns: /sbus@1,f80000000/cgthree@3,0.  This option could be used to create a symlink for /dev/fb to the actual console device. 

−p Display information derived from the device tree provided by the firmware (PROM) on SPARC platforms or the booting system on x86 platforms. 

−V Display platform-dependent PROM (on SPARC platforms) or booting system (on x86 platforms) version information. This flag must be used by itself, because it overrides all others. The output is a string. The format of the string is arbitrary and platform-dependent. 

−D For each system peripheral in the device tree, display the name of the device driver used to manage the peripheral. 

EXIT STATUS

If successful, prtconf returns 0.  If an error occurs, prtconf prints an error message and returns 1.  For example, when an illegal option is specified, prtconf returns 1.  On a SPARC system, when the −F option is specified and the console output device is not a framebuffer, prtconf returns 1.

NOTES

The output of the prtconf command is highly dependent on the version of the PROM installed in the system.  The output will be affected in potentially all circumstances. 

The driver not attached message means that no driver is currently attached to that instance of the device.  In general, drivers are loaded and installed (and attached to hardware instances) on demand, and when needed, and may be uninstalled and unloaded when the device is not in use.
