The Deliverator – Wannabee

So open minded, my thoughts fell out…

If only XP were this easy to reinstall…

I did a complete reformat/reinstall on my Jornada today. On a normal PC, reinstalling the OS and all associated applications would have taken the better part of a day, but it only took me about an hour on my Jornada. The Jornada’s OS (Handheld PC 2000 – based on the Windows CE 3.0 Core) is stored in ROM, with applications and user data installed in ram or to a storage card. I have been careful to store everything that can possibly be installed on a storage card, rather than waste precious ram. This and a LOT of tweaking has enabled me to keep a couple hundred apps installed on my Jornada while only using up 5-6 MB of the Jornada 720’s 32 MB of ram. Windows CE is a real fun OS to tweak and I have gained a pretty solid understanding of Win CE OS internals in the process. I have managed to screw up my Jornada a number of times from all the tweaking, but the ROM includes an excellent backup utility. I store my backups on my 512 MB CF card. If I manage to hose the OS while out and about, I can simply reset the unit, run the restore utility and have all my settings restored in a few minutes. Despite my best care, I have been accumulating cruft from applications that I have tried and subsequently uninstalled, leaving behind orphaned .dll files, registry entries and misc detritus. I decided it was time do a hard reset, wiping the ram and bringing the unit back to factory defaults. Most of my programs were installed to my storage card, so reinstalling was just a matter of reinstalling the drivers for my bluetooth and compact flash cards, reconfiguring a few programs whose settings were stored in the registry database (and were thus reset back to defaults when the registry got zapped) and installing a few applications that insist on being run from ram. I now have 3900 KB of ram in use, compared to ~6MB before the reset and my Jornada seems far more responsive than before.
