i had 2 zoom modems, and tried SEVERAL zoom drivers, which SHOULD HAVE WORKED. none did. no surprise. i typed in the chipset number, AGERE 1648C, and found the correct driver(s). if you have a zoom 2925n, YOU BETTER NOT THINK THAT THE COMPANY'S DRIVERS WILL WORK FOR YOU.
oh, did i mention that i think bill gates and his winXP... SUCKS??!!!!!! :))
