Brian,
Well I think I must be in the .00001%. I uninstalled the program, uninstalled the driver in device manager, removed mach3.sys from the found backup files, searched for any hint of Mach3.sys (hidden folders, system folders, etc) on the computer, deleted anything and everything related, and rebooted. Installed ver 3.042 and rebooted. Tried DriverTest and it gave zero for pulse/sec. Ran SpecialDriver then ran Driver Test and it gave the 36K pulse/sec. Ran Mach3 and still 0 for pulse frequency.
Thanks for the suggestion msraynford! Gave it a try with this new install and still nothing.
Now does the fact that I have to run the "no apic" SpecialDriver to get Mach to work with any version hint to any conflicts?
Thanks again. Roger
