V.90 Flash/Driver Updates for
Lucent & Rockwell Chipset Modems

These files are for use with Windows 95/98/ME/NT, unless otherwise noted. These files are not for use with Windows 2000.

You can determine if your modem has a Lucent chipset or a Rockwell chipset by the serial number of your modem. An "L" or an "M" in your modem's serial number indicates that you have a Lucent chipset. The absence of an "L" or "M" indicates that you have a Rockwell chipset. The modem's serial number is located on the bottom of external models and on the back bracket of internal modems (near the phone jacks).

"n" is any integer from 0-9 in the following examples:
nnnn-Z2925-nn-nnL-nnnn uses a Lucent chipset.
nnnn-Z2925-nn-nnM-nnnn uses a Lucent chipset.
nnnn-Z2925-nn-nn-nnnn uses a Rockwell chipset.

These chipsets differ in manufacturer only and offer the same functionality. Please note the presence or absence of an "L" or "M" in the below model #'s when selecting files for your modem.
Product with Lucent chipsets will also have a Lucent sticker on the front of the box.
