Patent ID: 7167945

Claim:
A method for programming non-volatile memories in an x86-based data modem having a JTAG port using a in-circuit emulator, comprising the steps of: resetting a communication system so as to place all components into a known state; utilizing the emulator to seize control of a main processor of the communication system via the JTAG port; configuring a first chipset and a second chipset, wherein a configured first chipset provides access to system dynamic random access memory, and a configured second chipset provides a PCI-to-ISA/IDE bridge function; configuring the system synchronous dynamic random access memory; load a first binary image and a first non-volatile memory burning program into the system dynamic random access memory by way of the first chipset; programming the first non-volatile memory with the first binary image by executing the first memory burning program to effect the transfer of the first binary image from the system dynamic random access memory to the non-volatile memory through the second chipset.
