ATI vs MWAVE
knock-down drag-out battle of the drivers
Many of those who have upgraded their ATI display drivers in the past with either the IBM upgrade files (ATI30C9C.EXE or APTATI.EXE) or drivers from the ATI website report GPFs during the install of the 20D drivers. One of the commonly reported errors references MACXW4.DRV, a common ATI device driver. MWAVE and ATI tend not to get along with each other and their ongoing battles are often bloody and error-filled. In the name of peace, and to avoid conflicts during MWAVE install you might want to do the following prior to running the 20D setup:
