Configuration Files

IRIX uses a number of configuration files to supplement its knowledge of devices and device drivers. This is a summary of the files. The use of each file for device driver purposes is described in more detail in other chapters. (The uses of these files for other system administration tasks is covered in IRIX Administration: System Configuration and Operation.)

Most configuration files used by the IRIX kernel are located in the directory /var/sysgen. Files used by the X11 display system are generally in /usr/lib/X11. With regard to device drivers, the important files are:

/var/sysgen/master.d.* Descriptions of the attributes of kernel modules
/var/sysgen/boot/* Kernel object modules
/var/sysgen/system/*.sm Device configuration information
/var/sysgen/mtune/* Values and limits of tunable parameters
/var/sysgen/stune New values for tunable parameters
/usr/lib/X11/input/config/* Initialization commands for Xdm input modules
