Re: Flashboard questions...

There is always room somewhere... I plan on losing the modem as soon as I 
can since I don't plan on using it..

just sucks...  I just wonder if you could tear both those  ROM chips off -- get 
a newer flash chip (Like from a Motherboard BIOS 512kb, just big enough to 
boot and load thebootloader and get the rest from the CF card) and wire it in 
place.

Chris:

Those are all excellent ideas - except (you knew it was coming, right??):

1. the ROM board and the Flash board look very different;
2. there isn't enough physical space to accomodate a CF card (check the Jornada archives);
3. if you could put a CF card in there, there's no room for RAM;
3. the circuitry to support MMC/SD/XD/whatever would require our own board anyway;
4. desoldering/resoldering surface-mount is not an easy thing to do, but a one-time soldering onto a blank board is (as long as the components are all on one side!); and
5. the chips used in the Jornadas and the original Jornada flashboards have all been EoL'ed anyway - even the Jornada's processor isn't made any longer.

Sorry, there just isn't another option other than building a new flashboard.  And the problem with building a new flashboard is that there is no way to get an initial flash without a custom flash programmer (e.g. flashing *after* the flash is mounted on the board).  If you try to flash *before* the flash is mounted on the board and you have a bad flash (or mess up during a subsequent update), you're royally hosed....
