Done and running! I did create my own problem by unzipping Nvflash.zip to a folder on my hard drive and then copying the .exe to a formated system floppy disk. In the process, I ommitted to copy CWSDPMI.exe which it ( nvflash.exe ) needs to run and NOBODY MENTIONED! I, too, also needed to use the -6 switch with the new rom.
I am using v. 81.94 from Laptopvideo2go.com with its modified INF File, which is working fine, but it is NOT WHQL, so I may eventually upgrade a version or two to one that is. ( Anyone know why the WHQL Certified Drivers have much smaller .exe files? )
Now it's working great!
Thanks, everyone! :-)
