A few month ago i stumbled onto a firmware call Legend for the F*nera, it comes preloaded with the aircrack suite and pre-patched MadWifi drivers for the atheros chipset that fon runs on. Which makes these little babies great for Wep key testing. The problem with this is the 8mb of storage the 2100 has.

I wanted something more permenant than a network cifs share. Now im not goin to run through how to flash legend onto the f*n as theres already a great guide which Prochobo wrote on fonerahacks.com found here,

This was what i came up with after looking at various sd/mmc guides and pinouts ive read..

Find a reader to victimize

Firstly find a sutable candidate to be pulled apart for the Sd/Mmc reader. An elcheapo usb reader will do the trick, just avoid combo ones like Mspro/sd/mmc ones (to many pins is a pain in the arse to figure.) Using a multimeter and the Sd card pinout below test for which pin you will need to solder lead wire to, i marked mine with a OHP pen to make it easyier.

Unscrew the F*n

Remove the two screws under front black pads on the bottom, unscrew the nut on the antenna jack. you should now be able to easyly remove the F*n's pcb. Looking at the topside of the board, underneath where you removed the antenna jack. There will be 8 empty points on the pcb. Ignoor the two outer ones as these are unused, the picture below shows Sw1-6 and also capasitors(C142, C143, C144, C145.) Remove these caps with twezzers or desolder them, just make sure you don't short any of them.

The clock signal (sclk) will be dirty if you don't remove these, trust me it will still work with out them.

Solder it up

Solder wires onto the Sd/Mmc card reader as marked on the Sd card pinout, you only need the contacts marked red. Solder these wires to the F*n board as in this chart

The Vss+ and Vcc- can be soldered to the fon serial pins like so.

Fix it all in

The best place i could find to mount the reade in the F*n was on top of the metal cage next to the heat sink.

Using a Dremel I cut the slot for the card reader, and hot glued it in place. I later realised this wasn't such a great idea, because of the heat from the F*n.

Check your logs

Power it up with a formatted card, using ext2 is best as it removes the need for the kmod-fs-vfat driver to read fat (windows) filesystems.

Check the syslogs from the webinterface you should see this at the bottom if it works.

Install the drivers

Download Phrozens mmc driver, and if you need FAT filesystem access you will also need kmod-fs-vfat These can be installed by copying them to /tmp then running

ipkg install package_name.ipk

or via the web interface, you may have to create a cifs based swap to install these. nows the time to test it all so reboot, ssh in and type the command

mountmmc

The card should now be mounted on /mnt/mmc and working.
