I've recently bought an Elonex EB-600, that is, a rebranded Netronix Device, as you know.

Since then I've tried to use other Firmware, via SD-Card. No Success till now.

As far as I know, several available firmwares should be compatible with the EB-600 model.
Yet none worked.

I assume I'm doing something terribly wrong - unless it's necessary that the current firmware actually helps the new one?

I'm not sure I understand how the new firmware is started, btw - it seems to me that every version has it's own file names, so it can't be names alone.

From a post here I gathered something in the Device looks at a certain sector(the first GB apparently) on the SD-Card and loads the boot record from there - is that correct?
If so, what exactly is looking for the "boot record"? Is there a Bios in there? (I'd assume this would be the Linux from Netronix? With the software from Elonex put atop?)

Could it be the Elonex software prevents other firmware being used?

Any ideas what I should try?

(I know this isn't really that much about OI, but I didn't find another forum more fitting. I didn't want to post in one of the more specialised forums, even if it's EB600-hardware. Unfortunately, there is no generic EB600 forum. If there is a better forum, it would be kind if a mod could move this thread there.)
