System Configuration Files

System Configuration Files

The files /var/sysgen/system/*.sm direct the lboot command in loading the modules of the kernel at boot time. Although there are normally several files with the names of subsystems, all the files are treated as one single file. The contents of the files direct lboot in loading components that are described by files in /var/sysgen/master.d, and in probing for devices to see if they exist.

The exact syntax of these files is documented in the system(4) reference page. The use of the VECTOR lines to probe for hardware is covered in this book in the context of each type of attachment. For example, probing for VME devices is covered under "Configuring the System Files".
