Well, > Why the hell can't PalmOS get installed/upgraded from Linux? That doesn't make much real sense to me.. the connection to the PalmOS device is a simple serial interface. Any task that Win32 can perform with a serial interface, can also be done in Linux (only better :). Since the OS upgrade is just a serial transfer, I image that the Linux pilot-link suite should be fully capable of this, with only a little hacking. Heck, you might be able to do it with minicom... The question in my mind is, what is the 'magic bullet' that turns a run-of-the-mill app install or data fetch into a flash-OS programming operation? If this is not already documented, it should be possible to log the entire transaction between the PC and the PalmOS device performing an OS upgrade (Win32 SoftICE?), and then begin reverse-engineering the procedure from that data. I doubt there is any form of encryption used. Or maybe I'm oversimplifying it.. -- Bill Layer Sales Technician <b.layer at vikingelectronics.com>
