Chassis ID

Chassis ID

The Chassis ID or Chassis Type is internally used to identify the so called Range of Target Hardware (the motherboard and it's original planned surroundings) of a PS3.
The Chassis Type only consists of one letter, it should not be confused with the letter appearing in the SKU model name of phat consoles (e.g. CECHAxx).
The SKU model names of prototypes allow you to get the Chassis Type reliable (e.g. DEH-FH1500J-A for a CECHLxx prototype),
you can also find the Chassis Type in the Platform ID and only on prototypes also on labels (e.g. F or N) and inside the cISD1 board_id.
The PS3 firmware actually uses the Product Sub Code to derive the Chassis ID.
Since the Chassis Type only gives you the Range of Target Hardware you need to consider the Platform ID, which holds an additional numeric value, to identify the actual revision of the target hardware.
