If the ACT LED blinks in a regular four blink pattern, it cannot find bootcode(start.elf).
If the ACT LED blinks in an irregular pattern then booting has started.
If the ACT LED doesn't blink, then the EEPROM code might be corrupted, try again without anything connected to make
sure. For more detail please check the Raspberry Pi forum:
