Basics The Cuda Chip - 16
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 red
Cuda reset button on the logic board to reset the Cuda chip.
(See "Logic Board Diagram" later in this chapter to locate
the Cuda reset button.) If you continue to experience system
problems, refer to “Resetting the Logic Board” in this
Basics chapter.
