Angie and others: The firmware is currently about 152 KB, but we don't want to commit to the = firmware being any size in the future. An appropriate error message will = be given if the card fills while sending the firmware update. For now, plan on having at least 200KB free, and things should be fine.

Angie <<The firmware update file gets stored on the card, then when you unplug =3D Book Port from the USB prot, the firmware reads the file, updates the =3D brain, then deletes the file.>>
