Hey guys! So since posting in April that I was having trouble getting REX to work, there's been a little progress, but not a lot. Stephen kindly supplied me with a ROM file that was compatible with the REX and using a company Kurt had told me about. I had a new System ROM burnt for my machine.
The ROM arrived last week and after installing it, the REX still doesn't respond to the CALL63012 command. When I input that command, the machine locks up and only by pressing the RESET can I get it back. This also has the side effect of wiping clean the computers memory, which I thought was interesting, because pressing the RESET shouldn't do that. Only a hard reset zaps your ram (unless I'm mistaken?). Stephen asked me if i could do a system dump and compare results with (I believe) the original file he sent me. However I'm not entirely clear on the method he wants me to use, e.g Am I comparing the file sizes of each file or something more involved like comparing the contents? The latter of which I wouldn't have a clue about. The system dump I made over the weekend curiously comes to 64kb, while the image file Stephen sent me weights in at 32kb. I'm a little confused why the dumped file is twice the size, surely it should be the same size as the file Stephen sent me. File size aside, everything else about the ROM seems to work, except I'm still having issue with the REX. So either the fault is with the module or my M100, or there is something else about the EU M100 that makes it incompatible with REX. As its been established the motherboard and the system rom of my machine differ from US machines. The only part of that which bothers me, is compatibility. It just seems like bad business sense to make US and EU machines so radically different. that they can't share addon modules. Well thats the slog so far, big thanks to those people who have helped me on this. It sucks big time that it didn't worked out the box, but at least we know that EU M100's are funny buggers...well mine is at least! lol <http://www.buyicnow.com/it.php?i=72>
