The were somewhat famous in the mid 90s to early 2000s for building motherboards with fake cache chips on 486 boards, including modified BIOS to show the presence of a cache when there wasn't one, and relabelled chipsets (socket 5, 7 and slot 1) suggesting they were better than Intel's. Founded in 1984, they later became one of the major shareholders in Elitegroup (ECS) in 1998 and finally merged with ECS in 2005. PC Chips (Hsing Tech Enterprise Co.) was a low-end motherboard manufacturer for the IBM PC and its compatibles during the DOS era.
