== A Little History ==

To provide some background, m0n0wall is a PHP based management layer on top of 
FreeBSD. Management of FreeBSD based software service is provided to the user by 
exposing a HTML based user interface.

The intent is probably similar to projects like Webmin. In contrast m0n0wall 
doesn't provide a general purpose administration interfaces but puts an emphasise 
on a FreeBSD based administration facility. Additionally, compared to Webmin, 
m0n0wall is pretty lightweight and fits on a small sized compact flash card which 
may then serve as a foundation for an embedded firewall system.

== About (Embedded) Firewall Hardware ==

Embedded firewall systems are regularly run on embedded boards like the Soekris 
boards with the following specifications:

 * 433 to 600 Mhz AMD Geode LX single chip processor with CS5536 companion chip
 * 128-1024 Mbyte DDR-SDRAM, soldered on board
 * CompactFLASH Type I/II socket, 8 Mbyte to 32 Gbyte FLASH or Microdrive
 * UltraDMA-100 interface with 44 pins connector for 2.5" Hard Drive
 * Serial ATA 1.0 interface for Hard Drive, with +5V and +12V power header
 * 1-4 VIA VT6105M 10/100 Mbit Auto MDIX Ethernet ports, RJ-45, protected with 2KW/100A TVS

 * USB 2.0 interface, one internal, one external port
 * Mini-PCI type III socket. (for t.ex. hardware encryption or wireless controller)
 * PCI Slot, right angle 3.3V signalling only, dual PCI slot option

Source: []

A PCI slot and SATA/PATA should be considered optional because they are still not 
commonly found on embedded boards.

Another embedded device having even more constraints regarding computing power 
is the Armadillo-300 Series:

 * CPU Clock: 200MHz (ARM926EJ-S)
 * 10BASE-T/100BASE-TX Ethernet port
 * USB2.0
 * miniPCI IEEE802.11a/b/g module
 * CompactFLASH Type I/II socket

Source: []

At least on such embedded devices, computing power and the amount of RAM
available should be considered as a constraint that will influence the design of 
the Bennu system.

Of course a software system designed for embedded x86 based hardware may run on 
regular x86 based hardware as well.
