			==Processor==
			The Linksys processor is a 200MHz MIPS32 core which has a memory management unit with simple fixed mapping translation (FMT) - see this link for more details - so FreeBSD may be possible!

			description of MIPS32 core

			Reminder of other details:

			RAM: 2 x IC42S16400, 64Mbit (4M X 16) RAM chips (16MB)
			Flash: Intel TE28F320 C3 flash 32Mbit chip (4MB)
			CPU: Broadcom [WWW]BCM4712KPB, running at 200MHz
			Ethernet: [WWW]ADMtek ADM6996 5 port 10/100 switch
			Wireless: On board; Broadcom BCM2050KWL

			==Linksys WRT54G specs summary==

			Specs

			Ports:

			* WAN: One 10/100 RJ-45 port for WAN connectivity
			* LAN: Four 10/100 RJ-45 Auto-MDI(X) switched ports
			* WLAN: 54mbps 802.11g on a MiniPCI card (1.0)/built-in (1.1) with dual external RP-TNC antenna ports

			LED Indicators (1.0):

			* Power, DMZ, Diag
			* WLAN: Act, Link
			* LAN: Link/Act, Full/Col, 100
			* Internet: Link/Act, Full/Col, 100

			Channels: 1-11 (USA)

			System requirements: One PC (200MHz or Faster Processor) with: 64MB RAM, Internet Explorer 4.0 or Netscape Navigator 4.7 or Higher for Web-based Configuration, CD-ROM Drive, Microsoft Windows 98, Me, 2000, or XP, a 802.11g or 802.11b Wireless Adapter with TCP/IP Protocol Installed or Network Adapter with Category 5 Ethernet network cable and TCP/IP Protocol installed

			In the box: Wireless-G Broadband Router, Power Adapter, Setup CD-ROM with User Guide, Ethernet Network Cable, Quick Installation guide, Registration Card

			Device details:

			* Width: 7.32 inches
			* Height: 1.89 inches
			* Depth: 6.89 inches
			* Warranty, parts: 1-year limite
			* Warranty, labor: 1-year limited

			Transmit Power: 15 dBm (Can be increased to 20db/84mw) (FIX: 84mw=19.24db) Info: 15db=31mW 17db=50mW 20db=100mW

			Receiver Sensitivity (unconfirmed):

			* -65db for ofdm 802.11g 54 megs
			* -80db for dsss 802.11b 11 megs

			Power (1.0?): 5V @ 2.0A, center

			Power (2.0): 12V @ 1.0A, center positive. (Regulated internally down to 3.3V by an AnaChip? 1501-33, so the unit should be very tolerant of input fluctuations from 5 to 40 volts. Get the polarity right and it'll make do with whatever you give it.)

			To turn on ripd and zebra, go to Advanced -> Routing -> Dynamic Routing and click Apply."

			linksys: adding files to the code.bin firmware

			Community I developed a script to add custom files into the Linksys filesystem. This was needed, for example, to add ripd.conf and zebra.conf to /usr/local/etc for the zebra routing daemon.

			This is how it works ($LINKSYS_SRC is the directory of your linksys source code eg. /home/djohnson/downloads/linksys/sveasoft/Alchemy-2.3.4/)

			1. Copy the script (makeimage.sh) to $LINKSYS_SRC/src/router
			2. Copy files that you need to the $LINKSYS_SRC/src/router/mipsel-uclibc/target directory (you can make directories and add/delete files in here)
			3. Execute the makeimage.sh script from the $LINKSYS_SRC/src/router directory
			4. A new code.bin will be built which can be uploaded to the linksys box

			The makeimage.sh script looks as follows:

			#$include .config
			#iLINUIXDIR=(shell pwd)
			#echo $LINUXDIR
			#export LINUXDIR
			#export PLATFORMDIR := $(TOP)/$(PLATFORM)
			#export INSTALLDIR := $(PLATFORMDIR)/install
			#export TARGETDIR := $(PLATFORMDIR)/target

			../linux/linux/scripts/squashfs/mksquashfs mipsel-uclibc/target mipsel-uclibc/target.squashfs -noappend
			cp ../linux/linux/arch/mips/brcm-boards/bcm947xx/compressed/vmlinuz mipsel-uclibc
			../../tools/trx -o mipsel-uclibc/linux.trx mipsel-uclibc/vmlinuz mipsel-uclibc/target.squashfs

			cp ../linux/linux/arch/mips/brcm-boards/bcm947xx/compressed/zImage mipsel-uclibc
			dd conv=sync bs=64k < mipsel-uclibc/zImage > mipsel-uclibc/linux.bin
			cat mipsel-uclibc/target.squashfs >> mipsel-uclibc/linux.bin

			cp mipsel-uclibc/linux.trx ../../image/linux.trx
			cp ../../image/linux.trx ../../image/code.bin
