The Cuda Chip - 61

The Cuda Chip

The Cuda is a microcontroller chip. Its function is to 

• Turn system power on and off

• Manage system resets from various commands

• Maintain parameter RAM (PRAM)

• Manage the Apple Desktop Bus (ADB)

• Manage the real-time clock

Many system problems can be resolved by resetting the Cuda 

chip (see Symptom Charts for examples). Press the Cuda 

reset button on the logic board to reset the Cuda chip. (The 

Cuda reset button is at the edge of the logic board near the 

PCI slots. See “Logic Board Diagram” later in this chapter.) 

If you continue to experience system problems, refer to 

“Resetting the Logic Board” in this Basics chapter.
