You can also download the source code and modify the bootloader yourself (see this page for more details and a link to the source). There are alternative bootloaders that eliminate these delays, including the Diecimila bootloader, the Adaboot bootloader, the LilyPad bootloader, and others. This delay also occurs when the Arduino is powered up, or after programming. The bootloader on Arduinos prior to the Diecimila imposes a 10 second delay after resetting, while it waits for information from the Arduino software. Replace the existing bootloader with a different bootloader.This is unlikely to be the case with a Mini, since the chip is not replaceable, and all Minis have the bootloader installed when shipped. This might happen if you have replaced the microcontroller with a new chip. Your Arduino does not have a bootloader on it.There are at least four reasons why you might need to do this: When we refer to "bootloading" the Arduino, we are talking about using a special device (called an In-System Programmer or ISP) to replace the bootloader software. The bootloader is what enables you to program the Arduino using just the USB cable. This is important, because normally you need a special device to program the Arduino. Its main function is to wait for the Arduino software on your computer to send it a new program for the Arduino, which it then writes to the memory on the Arduino. The bootloader is the little program that runs when you turn the Arduino on, or press the reset button.
What is a bootloader, and what is bootloading? If you know what a bootloader is, why you want to do it, and are just looking for specific instructions for the Arduino Mini, then skip ahead to the section called "bootload the Arduino Mini".
