Solution

1. Reseat the SDRAM DIMMS. Note: The computer does not come with any on-board memory. You must have an SDRAM DIMM installed for the computer to start up properly.

2. Verify that only PC-100 SDRAM DIMMs are installed and not EDO memory.

3. Run MacTest Pro and located the bad SDRAM.

4. Replace the SDRAM with a known-good DIMM.

Note: Wireless Internet access requires an Internet service provider (fees may apply) and AirPort (or AirPort-compatible) wireless Ethernet card and base station. Some ISPs are not compatible with AirPort. For more information, see technical document 106590: "AirPort: Requirements for Wireless Internet Access".
