Thanks, OS4User. I will go that route when I get a chance. As I work with QSINIT to find the rest of my RAM, I'm seeing a conflict with the Arca Noae release of MultiMac (R8169.ADD). This may affect the OS4 loader as well. If I revert to MultiMac from eCS 2.2 b2, QSINIT works well to show the full RAM of the system.
