I just bought this "Planet" modem and i installed it on a P III 500 Mhz (ABIT BE6 Motherboard). Windows XP Recognized it as "Generic Soft56k Data Fax Modem" but it worked toooo slow! i also tried it on a Athlon XP 3200+ (Asus A7V8-X Motherboard) it recognized it the same way but i had tons of blue screens (yeah same crap stable in time from Win95... Sux!!). i installed those drivers from the original CD it had inside (yeah read the R.T.F.M. out there lad!!). So dudes (and why not pretty chicks too!) install THIS driver and don't let windows install their generic so as not to happen those that happened to me! Cheers!
