Seeking Serial Bootloader Code for MC9S12A256B - orange107bc - Apr 27 22:39:00 2004

I need this information to help me determine where the bootloader code
is initially stored on my New Micros, Inc. NMIN-12A256B board. I am
also looking for how to use the Dbug-12 monitor on this board using
the serial cable to my PC. I find the User Manual very skimpy on using
the bootloader and the Dbug-12 monitor. It seems that the serial
bootloader in initially stored in Flash then moved to RAM, but before
I can download a new application, I must first erase Flash and I'm
afraid of losing the bootloader code and never being able to download
another application again.
Anyone else having problems with the user manual?

Gil
