Some information needed about memory in the Wizard

[azmerlin]

Hi all,
Can someone please explain to me how the memory is configured in the wizard ? When I look in the Settings>>Memory>>main, I can see that I have Storage memory ( 42.55 Total) and Program memory ( 44.01 Total)
In both areas I have almost 25mb free, what is actually stored in each ? Where is the ROM stored ?
I have read about the 'Extended Memory' is this in one of these or is there another area ? I have read that it is possible to unlock the extended memory, what exactly does that mean, what can I do with this unlocked memory ?
Is there a way to store programs is a memory area where they will not get deleted after a hard reset ?
Hope some one can clarify these points to me.
Chees AZ :roll:

Here is the explanation. It is the same for all WM5 based phones:

1) Program memory - This is your RAM. Just like in the PC it is the memory used to run programs. Part of it will always be used by the OS and other things you have running in the background, which is why you never get all the 64MB printed on the box.

2) Storage memory - This is like your hard disk. It's actually flash memory (just like disk on key) and is used to store files, settings, and all the outlook databases. It is deleted when you hard reset the device.

3) Extended ROM - This is another partition of the flash memory, but unlike storage memory it is hidden and read only. Usually the cellular provider puts it's customization cabs there. If you check the Wizard section of the wiki you will find a tool that will make this partition visible and writable so you can use it just like a built-in storage card. It's contents will not be erased during hard reset, but it will become hidden and read only again.

4) ROM - This is where your OS is stored. It isn't really ROM, but another partition of the same FLASH that contains storage and extended ROM, except it is always hidden and can only be written to by special programs (like the ROM updater). The files there are organized in a special way so they are ready to run and you can see most of them in your windows directory.

On the box of your (and most new devices) it says 128MB ROM. About 64 of those are the OS, another 10MB extended ROM and the rest is storage.
