REB1200 EJFM, an Overview – First Page Commands

As we mentioned in our first article, one of the great “easter eggs” of the REB1200 firmware is a mode called EJFM.   EJFM is part test mode, part setup, part rescue console – one of the nicest looking, and best outfitted management routines we’ve found.

This article will give a little overview of the features and whatever explanations and notes we may have written down on those features as they were explored way back when.
First things first – the ebook’s keys.   When the REB is in EJFM mode, pressing the Menu key launches the “execute command” routine with a few more choices of interesting things to do.   We’ll get to that later, as we consider it somewhat of a second page of choices and we’d like to address the first page first.

Back to buttons: Pressing the Shortcut key (Called Book key in EJFM) fires the BabyFinder, a sort of shell terminal that you can use to access the device with a little more flexibility than the standard page of menu choices.   Or for those folks with the proper authorization – some real gems await.   But that’s the topic of another story, so let’s get back to the program.

Sorry for the crummy pic, but we’ll do our best to list and describe the commands in human-friendly HTML.   Starting from the top, moving from left to right:

Xmodem – Sets up acceptance of an Xmodem transfer of a firmware image.   Selecting Xmodem gives you the additional choice of where to place the firmware: ROM, FlashDisk, Expansion, Emerg, or RES.

• Not sure if the device can Xmodem over ethernet, never tried.   And we never used the actual modem on this beast so this downloading has been unexplored so far.   But the choices seem very clear:

1. ROM – Download firmware into flash.
2. FlashDisk – the internal storage, called B:\ IIRC.
3. Expansion – The CF card, called C:\.
4. Emerg – intriguing, but untested – an emergency loader, perhaps?
5. RES – Download to current directory, as described by the menu
