Error generation
The error is generated when the data from the EEPROM is not received correctly.
EEPROM (Electrically Erasable Programmable Read Only Memory): A memory chip that holds
its content without power. It can be erased, either within the computer or externally and usually
requires more voltage for erasure than the 5 volts used in logic circuits. It functions
like non-volatile RAM, but writing to EEPROM is slower than writing to RAM.
Supposed
Causes
The possible cause is a malfunctioning indoor PC board.
