Edward Flottwell <edward@mudhoney.mitropa.com> wrote the following about his kernel patch for allowing the kernel to work with an adapted AS400 keyboard. (In fact no kernel patch is required - the utility setkeycodes will do. But the technical info below might be useful for somebody.) ----aeb "Keyboard.c patch for IBM Keyboards" (Aug 9, 20:04): > The last 2 Weekends I spent on hacking a little bit in the keyboard code to > make a keyboard from a IBM AS400 Terminal work with LinuX.

( README.AS400 ) --------------------------------schnipp----------------------------------- Connecting and using a non standard IBM keyboard by Edward von Flottwell edward@mudhoney.mitropa.com If you would like to use an old IBM 122-key AS400 Terminal keyboard with Linux, you should to do some small things: 1. Get your 'new' keyboard from a recycling company. If you haven't done this already :-) 2. Solder a new 5pin DIN Connector instead of the RJ/??? Plug to the wire. 3. Patch the kernel and build an new one. 4. Load a new keymap and fit it to your needs. I hope you managed the first step - so I'll continue with the second one: Get a keyboard connector from your nearest electronic-shop, cut off the original plug and you will hopefully find 4 colored wires: black, red, yellow and white. Connect them in the following way with the DIN Plug: Wire Signal DIN ___ Black +5V 4 / 3 \ Soldering White GND 2 (2 4) View Red Data 3 \1^5/ Yellow Clock 1 BUT BE VERY CAREFUL!!! Connecting the wrong signals can damage or blow up your keyboard or your mainboard! The table above comes with NO warranty, because I don't believe IBM always use the same type of cable :-} You should open the keyboard and trace the wires to find the matching out. And you should consult your mainboard for the keyboard-plug layout! Now you're ready to switch on the computer... Some mainboard bioses will produce a keyboard error. You can ignore this :-) BTW the F1 key is the very left of the function-key group near the tabulator key. O.K., now you can try to type something, e.g. LILO: linux :-) You will find out that some keys are swapped, others are dead. To make all of the keys work apply the kernel-patch to /usr/src/linux/drivers/char/keyboard.c and comment the lines with /* #define KBD_IS_FOCUS_9000 */ /* #define KBD_IS_IBM_AS400 */ out. Recompile and install the new kernel. Now you need the last missing part: the keymap. At the end of this README you will find an example for German users. How to make it fit to your national keyboard is explained in the Keystroke-HOWTO. Most other questions about keymaps, scancodes,... are explained there, too. I would also suggest you read the manpages of showkey and loadkeys. Don't forget to load the keymap every time you boot, I prefer the rc.local shellscript doing this for me :-) The keymap: # # File: AS400.map # keycode 0 = keycode 1 = Escape Escape alt keycode 1 =
