• Faulty or Leaking Electrolytic Capacitors

Some motherboards may contain faulty or leaking electrolytic capacitors, which can negatively impact system performance or stability. These capacitors may exhibit issues such as bulging, leaking, or even exploding, potentially damaging other components on the motherboard. Users should inspect their capacitors regularly and replace any that are faulty or leaking to avoid damage or system instability.

• Engineering Sample

This is an engineering sample, not a final product, for testing and evaluation.

1. Compatibility: Limited compatibility with hardware, software, or peripherals.
2. Stability: Potential for crashes, freezes, or unexpected behavior.
3. Performance: Differences in memory bandwidth, data transfer rates, or overall system performance.
4. Feature Limitations: Missing or incomplete features compared to the final product.
5. Engineering Features: Additional options or settings not found in commercial versions.

Intel 850-based Socket 478 engineering sample motherboard. Likely the earliest Socket 478 motherboard known to exist.

The D-0015 BIOS was seemingly compiled on July 30, 2001, predating the official Socket 478 launch by at least about a month.

Judging by the "WN" portion of its name, its codename might be "Winnipeg", which would have been re-used for the D845WN.
