#5880, "RE: MS2 Daughterboard upgrade for MS1 v2.2" In response to In response to 0
Looks about right. I have never constructed a MS1 and later upgraded to a MSII processor, but as long as you follow the manual you should be safe.
http://www.msextra.com/doc/index.html#ms2 is the place you should be at, as the /Extra code is the most up to date etc, however they do not have anything related to running an MSII chip in an old 2.2 board. Follow what you have, and check the MSExtra forums for the easiest support as there are always active members there.
