Only modules that have been imported into the "Available Modules" area are in flash.

Ah! Okay. I assumed that the need for copying modules to the dedicated flash area was so the CPU could address them directly from a consistent (non-FAT) location.

How is the HEPAX RAM handled on the DM41X? i.e. how do I make sure RAM isn't lost when swapping modules and such? Do I just need to use the "Save RAM Pages" function to safeguard the contents?

I'm looking through scans of Datafile for HEPAX info, and found this in V6N8:

"Since HEPAX organises its memory as blocks of ROM then a HEPAX 4K or 8K block of programs (or data) can be directly copied to, say, a ZEPROM to make it totally permanent. Building your own custom ROMs is now within the reach of everyone."

So it sounds like that will meet my needs. Do I need to worry about setting a module name or XROM ID with this approach?
