"In  1990 the  company  introduced Single  Chip  AT Controller  (SCAT)
technology, by  which the  functionality previously found  in chipsets
could be integrated  into one chip. In turn,  integrating several SCAT
chips,  the company  introduced  the Entry-Level  Enhanced AT  (ELEAT)
CHIPSet,  a  platform  incorporating  systems  logic,  graphics,  data
communications, mass storage, and BIOS."
