Unplug the modem on the PCI slot and read part number on the Conexant chipset. If the
chipset has part number R6795-XX on the one chip modem (Picture 1) or both 11229-XX and
RLVDL56DPF/SP R6785-XX or both 11235-XX and RHP56D/SP R6789-51 on the 2 chips
modem (Picture 2), it is a HCF modem. If the chipset has part number R6793-XX, it is a HSF
So mine is a HCF modem:)
But should I use Modem driver from Conexant or Interstar????
