Remove Level 2 Cache Card
1. Identify the internal components of your Power Macintosh.
Touch the power supply metal shielding (Figure 3) to discharge
any potential damaging static electricity.
2. If installed, remove the Level 2 cache card (Figure 3) located next
to the CPU.
Reset CUDA Switch
Reset the CUDA switch on the logic board (Figure 4). It is located
underneath the riser card brace, next to the power supply and cable
connectors. You may need to carefully move the cables aside to gain
access to the CUDA switch. Using a nonmetal ballpoint pen, press
down on the switch. Resetting this switch ensures that a processor
upgrade card installed into your computer is recognized at the
next startup.
