The slot numbers will display the same in the web interface, physically they will change though.
Ok it works well, i just tested it thanks to the |help command of XMEM.
Now there is one remaining problem, i don't know if you're the one that can help me :
I have M4board starting at slot 32, with the M4 relay rom on slot 6 of the XMEM.
It works well, the M4 board is started at launch at the same time that the XMEM...
... but, if i upload a application in slot 33 (i tried with protext and discology 6), i have the rom recognized by |help, with the RSXs described, but a "Unknown command" happen if i try to use a RSX (|p for protext, |d6 for discology6).
I guess i need something to relay the command to the upper slots (ie >31), as i guess FW315 only activate 32 roms, but i don't now what is needed, and neither if it even exists !
EDIT : everything works if i start the M4 board at, say, slot 26... so it's really a slot >31 thing !
