I tried another V.90 upgrade (prac5676.exe), but like many others, was told that my modem was not a valid practical peripherals modem,(even though it is).I then used this
file from flashcom,and had no problems
with the flash process. I used the driver from the win98 CD, and greatly
improved conectivity and download speed. I then upgraded to win2000, and the modem is still working great,
although I had to re-install it after the 2000 upgrade. Good Luck!
