The P6 / K7 MTRR management package has been updated (6/23/2001) to version 0.06b. This is a device driver that can manage MTRRs of Intel P6 / AMD K7 series processors. It includes VFBWC.exe, which uses MTRR write-combining for the video frame buffer; this can often improve graphic performance, especially DIVE.
