Methods and systems for fast Ethernet controller operation using a virtual CPU are disclosed and may comprise controlling an on-chip Ethernet controller utilizing a virtual CPU comprising a microcode engine that loads a single instruction and executes the instruction prior to loading or executing a subsequent instruction. The instructions may be fetched by the virtual CPU from an external non-volatile memory or on-chip ROM. The virtual CPU may initialize the Ethernet controller and provide patches for supporting hardware workarounds, wake on LAN service, and vital production data such as serial number, product name, manufacturer and related manufacturing data. The virtual CPU may power down the Ethernet controller and may be halted via a particular command and procedure.
