Different kind of ROMS...

[Z£Y$]

Ok i still in the process of reading various threats regarding ROM backups.

Can someone please clarify the differences between the three kind of ROMS:

WINCE ROM
Radio ROM
Extended ROM

As far as i can tell the WINCE is self explanatory -- its the OS

Which one of the rest 2 ROMS hold the settings of the provider.

E.g. If i want to upgrade my device to WM6 and want to reload the settings of my provider which one of the two i will have to use?

The radio ROM does what it says on the tin - it controls the radio.

The extended ROM is about 10Mb of memory used by the carriers for configuration / customisation information. It is usually programmed to autorun after a hard reset so that the customisation files in there can be processed first. For example, with O2 UK, the customisation puts in the GPRS/3G/locale settings, makes the Uni look pretty (if you don't use corporate mode) at the expense of it being very slow indeed!

If you empty the extended ROM, you then have 10Mb which you can use for storage / running progs. I run TomTom 6 and various other key apps from there with no difficulties.

The only downsides are if for some reason you need some particular form of customisation installed by your carrier. I have happily dispensed with all of the O2 customisation and all I have to do when I hard reset (after a new ROM) is to reinstall the O2 GPRS/MMS settings, which takes about thirty seconds.

If you do empty the extended ROM, bear in mind that it will be re-locked whenever you change the main ROM so you will need to unlock it again. Also, one of the unlocking progs around also wipes the Extended ROM - there is another (which you will find somewhere on this site) which only unlocks it.
