For the PCA200E adapter, if no file is specified on the command line a built-in copy of version 4.1.12 microcode is used. When the option -3 is specified version 3.0.1 microcode is used instead.
Microcode as distributed by FORE Systems is not ready for downloading directly into SBA host ATM adapters. Instead, the supplied microcode needs to be processed with the objcopy(1) command to create an image suitable for downloading. Arguments to objcopy(1) are ""-S -l -Fcoff"".
