82810e/DC-100 Integrated Graphics Controller
The Intel graphics controller includes special enhancements for 2D operations. Motion
compensation logic is included to improve performance during software decoding of MPEG2
video. Hardware cursor and overlay engines relieve software processing and provide independent
gamma correction, saturation, and brightness control.
The 230-MHz RAMDAC can support a variable-scan rate monitor up to a maximum resolution
of 1600 x 1200 with 256 colors. Video BIOS for the controller is held in the system BIOS ROM
and copied into systems memory at runtime for maximum performance.
