I.14 What are flash ROMs and how will they work?

--------------------------------------------------------------------------------

The current U-1496 generation of ZyXEL modems update ROM versions via a ROM
*replacement*.  This involves opening the modem, removing the ROM chips, and
inserting the new chips.

The new ZyXEL modems will have flash ROMs to facilitate ROM updates.  Users
will get a new copy of the ROM images, and run a program in DOS or in MacOS.
The new ROM images are sent to the modem, and the new images are "flashed"/
written to the flash ROM chips.  This method of ROM updates should be much
easier to perform.
