Most AVR models can reserve a bootloader region, 256 bytes to 4 KB, where re-programming code can reside. At reset, the bootloader runs first and does some user-programmed determination whether to re-program or to jump to the main application.

My ATTiny worked fine until I decided that I need to step up the clock speed from 1MHz to 20MHz so I selected ATTiny85 at 20MHz from the Boards menu and then clicked on Tools>Burn Bootloader. But that was stupid, since now my ATTiny doesn't work at all. I cannot upload sketches on it and if I try I get this message: avrdude: Yikes! Select ATTiny 8MHz from the list of boards and then select tools>Burn Bootloader. Everything else is taken care of and in a few moments your ATtiny85 will be configured to run at 8MHZ. This is necessary when timing is a crucial part of your program.
