This is the entire Driver disk that came with my Aims Lab Instant TV.
Although it was intended for Win `95, it seems to work fine for Win `98 as well. Just create a folder and unzip ITV.zip to this folder. Then from the start menu choose "Run", browse to the folder where ITV.zip has been unzipped, and select "Setup.exe". Run "Setup.exe" and it should be self installing from there. Good Luck!!
