Network Everywhere (Linksys) NC100

Network Everywhere Fast Ethernet 10/100 Network Card

The Network Everywhere logo, the above tagline, "Model No.: NC100", "A/N: PCB-E540-MA3", and "P/N: E540 Rev. A" is silkscreened on the top of the card.
 * All the radial capacitors on this particular board are STONE branded.

The Network Everywhere labeled Ethernet controller (NC100, C994031DBX) would simply seem to be a relabeled Macronix chip.
