XDA ll loses apps when battery goes flat

[peanut]

I have been given an 02 XDA ll at work to carry out some decent homes surveys .

The special software for the surveys has been installed but every time the battery is allowed to go flat the XDA re-installs windows and various apps on restart but loses the special survey software . This has to be re-installed which takes about a week to organise (Council)

Shouldn't all software the OS and apps be installed on non volatile memory ?

Can someone explain what the root structure is in these things and where software should be installed to please.
It has a external 1Gb memory . I can transfer the survey data and photos etc to that for safety . Couldn't we install and run the survey software from the memory card also?

xdaII's with wm2003 have all apps in normal mem and they will be lost if the batt goes belly up

with wm5 wm6 wm6.1 one get some flash storage and programs installed there and on the sdcard will make it passed a flat battery

but since the storage is limited in size
people use ramdisks which use normal mem as a disk
and that too can be cleared at flatbatt

thanks for your quick reply.
If all the apps are stored in non volatile memory where do they get restored from when the batt goes flat ? they must be stored somewhere in non volatile for restore purposes.?
Don't understand this at all.

If the XDA can store the OS and apps somewhere shouldn't my employers install the special app in the same place so that it doesn't get lost when the batt goes flat?

Can the firmware be updated on these ? if so what difference would it make
Thanks for any help

the os itself is located in flash and stay there unless it's flashed with another rom

on WM2003 many htc devices have a list of install cabs in what they call extented rom which are auto executed after a hardreset or 100% flat batt

one can open the extented rom and add install cab's oneself but the space in limited so it may require other of the auto install apps are removed

with wm5 and later it's the exntented rom which is used as normal data storage
so it's not really present there

yes the firmware/rom / os can be changed as i state when i describe the diff between 2003 and wm5 or 6 or 6.1

how one goes about that you can read in the wiki
or in the rom from the wm5 or wm6 sub forums you download they include a txt file
describing step by step what to do

thanks Rudegar
I have found a good explanation of the different types of memory in these pocket PC devices Here (http://www.pdagold.com/articles/detail.asp?a=243)

If our IT remove redundant OS files and some of the unwanted apps in the flash memory there might be room to install the special survey software (Anite)into the flash memory instead of into Ram that way we wouldn't lose the damn app every time the batteries go flat ?

Alternatively would it be possible to install and run the Anite app onto the SD card ? that way it would be safe and easier to re-install from and PC

Are the OS upgrades WM5 and WM6 available free to download or do they require a license like Winxp etc?

[Rudegar]

the roms wm5 and wm6 is not sold by ms they only provide them to the pda makers
so you cant get hold of them that way but if you go to the subforums for himalaya wm5 and wm6 you can find plenty of versions for free

thank you for your helpful advice. Much appreciated

Sounds very much like the battery has expired and is not holding a charge. Do you have a spare battery you could test with?
