P6K7MTRR.SYS: Difference between revisions

Latest revision as of 23:50, 4 June 2020

A simple interface physical device driver(PDD) that can manage memory Type Range Registers (MTRRs) of Intel P6 / AMD K7 series processors. Programmer can query/modify any MTRR settings via DosDevIOCtl() API, from non-Ring0 privileges. A sample executable, VFBWC.EXE, using P6K7MTRR.SYS, sets MTRR write-combining strategy to video frame buffer aperture. It can often improve graphic performance, especially DIVE. By Takayuki Suwa
