This is the memorandum recording the procedure I use burning Optiboot bootloader to Arduino Pro Mini.
The procedure:
1. Upload ArduinoISP sketch to Uno R3 as any general sketch.
2. Connect Arduino Pro Mini RST to Uno R3 D10, Vcc to Vcc, Gnd to Gnd, D11 to D11, D12 to D12 and D13 to D13 respectly.
3. Select Board -> Arduino Uno, Programmer -> Arduino as ISP, Burn Bootloader from Tools menu. Wait for a minute or so, the status bar of Arduino IDE will show "Done burning bootloader.".
That's it.
No need to download Optiboot hex file from any website, to compile optiboot from source or to edit board.txt, Arduino Uno use Optiboot as its default bootloader and the hex file is include in the Arduino IDE ( the Arduino IDE I use is 1.0.5-r2). The parameters set for Uno in board.txt is suitable for all boards using ATMEGA328P-PU or ATMEGA328P-AU microcontroller.
I burn Optiboot to Arduino Pro Mini following the procedure above and upload the example blink sketch to the Arduino Pro Mini by selecting Tools -> Board -> Arduino Uno repeatly and successfully.
If Arduino Uno R3 with ArduinoISP uploaded is used, skip to step 2 directly. Step 2 can be done before or after plugging USB type A connector to computer.
Following the procedure, I can minimize the needed size of board and bytes occupied by bootloader and maximize the functions the bootloader provides such as watchdog timer.

Burning Arduino Uno Optiboot Bootloader Using Duemilanove Compatible
This is the note recording the procedure I used burning the Optiboot bootloader to ATMEGA328P-PU microcontroller.
Tools used:
1. Duemilanove ( no need for adding a 10uF capacitor between rest and ground) compatible Justduino TTL ( I made a few years ago) with ArduinoISP uploaded (since Justduino TTL been made).
2. AVR ISP Shield (no need for wiring, more productive and error free).
3. Arduino IDE 0.022 and 0.023 (In Arduino IDE 1.0 and above, ArduinoISP sketch need to be modified, compiled and uploaded) .
Procedure:
1. Stack AVR ISP Shield upon Justduino TTL.
2. Power the Justduino TTL by plugging FT232 Cable compatible cable into USB port on computer, the PLS led on the AVR ISP Shield starts breathing:) ( Kit Review - AVR ISP Shield on tronixstuff.com) .
3. Open Arduino IDE 0.022 or 0.023 (I used both without fail).
4. Load ATMEGA328P-PU IC upon 28-pin ZIF socket and pull ZIF lever down.
5. Select the items in the Tools > Serial Port menus that correspond to the board you are using as the programmer.
6. Select the item in the Tools > Board menu that corresponds to the board (Arduino Uno) on which you want to burn the bootloader.
7. Select the w/ Arduino as ISP in the Tools>Burn Bootloader.
8. The PROG led will light on during the burning process, the process takes about one minute.
That's it. Easy!
After inserting the ATMEGA328P-PU upon the socket on the Justduino TTL, the D13 led doesn't blink the same way as the new Arduino Uno dose. I just compile the example blink sketch and upload it in Arduino IDE 1.0.5. Now, the D13 led blinks the same way as the new Arduino Uno does.
I find that I cannot re-burn the bootloader to the ATMEGA328P-PU.
Next Step:
I want to buy some Yamaichi IC51-0324-1498 socket and make some TQFP32 to TQFP28 adapters to stack upon the AVR ISP Shield for burning Optiboot bootloader to ATMEGA328P-AU for use on the coming projects featuring watchdog and software reset.
