There are TWO ways to do this without re-installing Windows NT. ONE method is: CD \winnt40\system32\drivers ren ATI.sys ATI.ati Windows NT looks for ATI.SYS drivers at boot time, so if it cannot find it, it cannot use it. SECOND method is: While running Windows NT, execute the Win NT Setup program. Select a NON-mach64 driver (try VGA-compatible) ***************************** 3.0 Known Problems Some applications do not handle 24bpp and 32bpp properly resulting in the colors not looking right. What to do if "ACCELERATOR not found" message appears: Is there another adapter card in the system that CONFLICTS with I/O locations in the 350-35F hex range? Relocate the I/O to 300 to 31F range. Attempting to run the mach64 Install program under NT will report "Mach64 Adapter not detected". The Install program must be run from DOS. ***************************** 4.0 Reporting Problems If you experience any difficulties, open the file REPORT.TXT and complete the Problem Report form.Download Driver Pack
