Diosdado P. Banatao (born May 23, 1946) is a Filipino entrepreneur and engineer working in the high-tech industry, credited with having developed the first 10-Mbit Ethernet CMOS with silicon coupler data-link control and transceiver chip, the first system logic chip set for IBM's PC-XT and the PC-AT, and the local bus concept and the first Windows Graphics accelerator chip for personal computers. A three-time start-up veteran, he co-founded Mostron, Chips and Technologies, and S3 Graphics. His father, Salvador Banatao, was a rice farmer. His mother, Rosita Banatao, was a housekeeper. Banatao is known for his rags to riches story. During his childhood, he walked barefoot on a dirt road just to reach Malabbac Elementary School. He pursued his secondary education at the Jesuit-run Ateneo de Tuguegarao. After high school, he pursued his Bachelor of Science in Electric Engineering from the Mapúa Institute of Technology and graduated cum laude. After college, he turned down several job offers, including one from Meralco. He joined Philippine Airlines as a trainee pilot, and later joined Boeing. At Boeing, he worked as a design engineer for the company's new commercial airliner and cargo transport aircraft, Boeing 747, in the United States. With the opportunity to stay in the United States, he then took his Master of Science in Electrical Engineering and Computer Science at Stanford University and finished in 1972. Banatao also joined the Homebrew Computer Club, where he met Steve Jobs and Steve Wozniak. After finishing his master's degree, Banatao worked with different technology companies such as the National Semiconductor, Intersil, and Commodore International where he designed the first single chip, 16-bit microprocessor-based calculator. In 1981, he developed the first 10-Mbit Ethernet CMOS with silicon coupler data-link control and transceiver chip while working in Seeq Technology. He was also credited for the first system logic chip set for IBM's PC-XT and the PC-AT; the local bus concept and the first Windows Graphics accelerator chip for personal computers. Career Business In 1984, Banatao and his business partner Francis Siu, founded a high-technology company, Moston, starting with a capital of half a million US dollars. Mostron was launched as a manufacturer of motherboards. They also hired Ron Yara of Intel as a company executive. After he developed a five-chip set, he co-founded Chips and Technologies in 1985. The company developed system logic chip set for IBM's PC-XT and the PC-AT. The company earned $12 million in
