The ROM routine used to load the OS is often known as the 'bootstrap', from the expression "pull yourself up by your own bootstraps". **The Article [[http://www.ucapps.de/mios_bootstrap_newbies.html|MIOS Bootstrap For Newbies]] (also available as [[http://www.ucapps.de/mios_bootstrap.html|MIOS Bootstrap]] in different languages) contains important informations about how to upload MIOS - the operating system - and an application.** If you buy the Pic microcontroller at SmashTV's or Mike's Shop you do not need to burn the bootstrap loader onto the chip. You can simply upload [[MIOS]] and the selected application by [[MIDI]] ([[SysEx]]). \\ {{http://www.audiocommander.de/pics/sonst/MIOS_Overview.gif}}
