A flash-upgradeable 2 MB ROM 56K chipset that simultaneously supports both V.90 and K56FlexTM. Voice [speakerphone] capable (depends on OEM implementation). Desktop, internal & PC-Card (PCMCIA) versions available.

Caution! Make sure that the flash upgrade is for the correct model. See Media Force for a cautionary tale. The better flashes check for the correct chipset before going ahead, & this chipset has many variants.
Flash "hangs" at 91% Go and make a cup of tea - the flashing process must not be interrupted or the modem will be useless, permanently. This behaviour is normal & it normally goes to completion in a few minutes.
Don't forget the drivers! Upgrading is often a 2-stage process:

    1 flash-upgrade the modem
    2 update the computer drivers
      Windows - INF file - the modem in Dial-Up Networking Properties (General page) will need changing if an upgrade causes a name change.
