He should install all necessary software and drivers in Win 2k. Then see if it still loads fast and runs fast in 128k on such a processor.
A friend of mine has a computer with 2 harddrives, one with Win98 on fat32 that on a 20gb harddrive the other has windows 2k on NTFS 60gb drive.He have optimum high speed internet on the 20 gb drive. If he loads the modem in win2k would he be able to run the optimum high-speed program from windows 2k. I am asking because the computer take days to load in 98 if the optimum is running then after it loads it freezes once u start using it. The Win 2k loads very fast never freezes. by the way its a celron 400mhz processor and 128mb stick of ram
