That company's GPU was used in a few of Intel's early Atom SoCs, and infamously lacked documentation and source code, unlike other Intel GPUs of the time. It was also dismal in performance and efficiency, lacking a blitter and other acceleration for 2D unlike nearly all PC GPUs since the original 8514.

Ironically the source and docs were leaked many years ago, causing a lot of commotion in the OSS community; and more relevantly to this article, a Chinese underground forums community managed to make a decent usable driver for Windows XP, something neither Intel nor Imagination had.
