This invention discloses a method for preventing BIOS from viruses. Electrostatic discharge protection circuitry is provided that prevents damage or undesired programming of the sensitive circuitry in the presence of an electrostatic discharge event. The graphical interface includes a map on which an area is traced to define a closed geographical area. A dummy photomask pattern is disposed in the third region and is structured to form a dummy wafer pattern on a wafer. An electro-active multi-focal spectacle having a blending zone is also disclosed. Reliability of the PDCP status and reset messages may be assured by acknowledgment according to an acknowledged mode or to an unacknowledged mode.
