I was trying to get the 90079-2 Riptide Modem/Soundcard combo board working on an HP Pavilion desktop PC (Pentium 3) without the original driver disc. This Riptide card is a combination modem and sound on the same PCI card. I got the sound card section working with the Chamelon.zip but it didn't get the modem section working. I used camhsf2k.exe to get the modem section working by using the NT52013 and restarted the computer. This was for the Conexant chipset. Took almost 8 hours of trying different driver combinations to get this combo board to work!
