NAME

prtconf − print system configuration

SYNOPSIS

/etc/prtconf [ −F ] [ −p ] [ −P ] [ −v ]

AVAILABILITY

SUNWcsr

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

−F 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 Displays information derived from the device tree provided by the firmware (PROM). 

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

−v Specifies verbose mode.

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.
