The automated extract and build scripts are pretty generic and target 
Linux-based firmware only. This 3COM router uses a RTOS (real-time operating 
system), and is not supported by FMK.

WIth that said, you should be able to use the tools included in the FMK 
(binwalk in particular) to identify the different sections of the firmware, 
which you can extract from the firmware image with dd.
