[NTLUG:Discuss] fundas gone for a toss!!

[Fred James]

Assuming we are discussing a PC
  - BIOS determines which device to boot from, reads the Master Boot 
Record (MBR) found there, and attempts to load the "boot loader" 
specified in the MBR
Assuming LILO is the boot loader specified in the MBR
  - At this point LILO is loaded, and the rest depends on configuration

But - lilo.conf is only read on install, and any time "lilo" is run - 
not on boot.

In short: lilo.conf is read by "lilo" and used to configure LILO, and 
this process only has to happen whenever there is a change in the the 
boot process (i.e., at install, or should you add/remove an OS to/from 
the machine - stuff like that).
