This procedure explains what to do to start an individual computer. If the system is operating correctly, things should pretty much happen as described. If there are problems, refer to the Linux manuals for more information.
Note that the file server computer should be the first machine started. Remember that the other computers use the file server.
Procedure 1.1. Linux Startup
Turn on the power.
Wait for the disk drive to reach its operating speed and for the machine to perform its power on self tests.
Wait for the booting menu to appear.
Press <Enter> (if you wait long enough the machine will proceed on its own)
Linux may decide to check the file system if it detects the computer was not shut down properly. If error messages appear while the file system is being checked, it indicates that there is a problem with the files contained on the disk. Usually it is safe to answer "y" to the questions fsck (the file system check program) asks. Sometimes the file system check will require a reboot of the machine.
When this sort of a problem occurs, it usually means that the computer was shut off or restarted in a disorganized manner. Perhaps the computer crashed, the power failed, or someone pushed the reset button. Consult the Linux manuals for more detailed information.
When the login prompt appears, the system is ready for operation.
