If any one wants to help with this Modem section of the site let me know. I don't have a lot of info on the modems used in eMachines, but I'll gladly post what-ever info you guys have.

Since eMachine Inc. used what-ever modem they had on hand, you may have to pop the case cover and physically look at your modem to correctly identify it, but I think these drivers will cover most everything eMachine uses.

In reference to the systems made in the 500MHz to 1GHZ range, these systems mainly use three different types of modems. One has a Rockwell (now called Conexant) chipset (either Rockwell or Conexant will be stamped on the main modem chip); one has a Lucent (now called Agere) chipset (either Lucent or Agere will be stamped on the main modem chip); and one has a PCTel chipset (either PCTel or PCT followed by numbers will be on the chipset). Some systems may have an AMR modem instead of a PCI modem (the AMR modem usually has the PCTel chipset, while the PCI modem will usually have either the Rockwell or Lucent chipset).

The following systems usually include Rockwell Chipset 56K V.90 based modems:
600is, 600id, 633id, 600ix, 600irx, 667ix, 633irx, eMonster 800, 700id, 766id, 667ir, 700, 700irs, 766, 566iz, 566ir, 700irx, eMonster 1000 and 633ids
