Why delete ext ROM?

[tinto]

It's a few month that i'm using my jam and i'm trying every day to learn something new to get the best from it.
Anyway i see many people here discussing on deleting the ext rom and i still haven't understood why i should i delete it. I know that by deleting it you can allocate more memory to your storage (http://forum.xda-developers.com/viewtopic.php?t=20043) but won't you loose some features? I've always thought that ext rom contained custom region/operators settings. Am i wrong? Then again, won't i loose them if i delete the ext rom?
Any info would be very appreciated, thanks in advance. :idea:

What Features do u lose?

that's exaclty what i'd like to know... if it's there i belive it should do something.

george, do you have programs like truefax installed without the ext rom?

The ext_rom is filled with some provider customisation,
it has about 20mb.

If you delete this extended rom u will have more space
available for other use, for example storing today plugins etc.

You don't have to 'lose' the extended rom. The data on the extended rom is only used after a hard reset to install some software and some operator customization.

You can easily do this by hand. Either download an appropriate extrom from the FTP here or...

- First install the rom with extended rom included.
- use Loadvdisk.exe in the windows directory to show the extended rom
- copy all files from the extended rom to your sd card (or pc)
- install the rom without the extended rom
- now install any files from your extended rom backup you want.

Presto, more storage and still all the functionality.

Or even simpler down load watever you want from the FTP itself evrthing is there..
The extended Rom Files are there in this server under the norwegian Ext_ROM Folder

Can I use the org autorun.exe file to execute all requested extended_rom pgm instead of instaill in one by one?

I'm curious if that would work as well. I wonder if the target install place would have to be modified. Of course that does kind of defeat the purpose, but even by installing all of the extended ROM, you should still end up with quite a bit more storage memory. My imate Jam 1.06 extended ROM install files are 8.5 megabytes. They could just as easily be kept on an SD card in case of a meltdown :shock:
In theory, that should still leave at least the original 7 meg (maybe more) plus the 8.5 meg (size of the extended ROM install files) free in the storage area for a grand total of 15.5 meg. (or more). Which still ain't bad for a fully loaded unit. Anybody abserve this?
