CHAPTER 8
Firebox Read-Only System 
Area
WatchGuard ships all Fireboxes with a fixed, baseline set of functionality 
stored on the read-only system area of the Firebox flash disk memory. It is 
possible to start the Firebox using this read-only system area when the 
primary user area is misconfigured or corrupted. This functionality 
allows you to:
Troubleshoot problems where all access to the Firebox is lost
Reset Firebox passphrases when you do not know or have forgotten 
them
Fireboxes shipped before Firebox System (LiveSecurity System) 4.1 
shipped with the original, standard functionality called the read-only 
system area. Fireboxes shipped with Firebox System 4.1 or later contain 
both the older functions and a new set of features designed to enhance 
usability, called the enhanced system area.
Read-Only System Area
All Fireboxes, both new and old, have a read-only system area which the 
unit can be booted into utilizing the serial cable shipped with the Firebox. 
When a Firebox is running from the read-only system area, the Sys B light 
on the front panel is yellow and the Armed light is green.
