Increase OS ROM and reduce EXTROM/STORAGE possible?

Hey, I have just had this idea.
We actually have a single ROM, which is segmented in 3 parts: ROM, EXTROM and STORAGE right?
originally we have 43MB for storage, 26MB for EXTROM and the rest (32MB? not sure) for the OS ROM.
originally, a way has been found out to reduce EXTROM to the minimum of 128KB and add it to storage, giving is a 60MB goodness of space.
The thing is, over time compaction can cause slowness, so it's preferred to use a storage card to manage data and keep internal storage empty, as BAs haev not been designed for WM5 (nor vs. nand and stuff, we know about that).
BUT compaction never messes with our IMGFS in the OS ROM right?
What if instead of adding the EXTROM space to torage we added it to OS ROM?
That would give us +16MB (more, since IMGFS is compressed) of OS ROM to play with.
That's an upgrade from a bacon-and-eggs kitchen to a Cordon Bleu Chef kitchen
Maybe even storage could be reduced to add even more OS ROM space...
OK, I have had the idea, what the ones which actually get their fingers greasy (Tuatara, mamaich, Bepe, Midget, Helmi & co.) have to say? Is it possible?

Htc should make its Diamond shine

With the latest rom upgrade to 1.37 the diamond is much snappier and is much much better than its original rom 1.35.
What is disappointing though is that the diamond comes with only 60Mb free storage for the user as compared to 115-150mb for the kaiser or tytnII(all these devices comes with 256mb rom)
Htc ought to install some of its default programs and files eg opera, music,ringtones and pictures,etc that had occupied space in the rom(storage) into its internal storage which had 4 gig instead of using the precious rom space that had only 256mb thereby freeing the rom storage space for additional programs to be install by the user.
Perhaps some rom developer can make a clean rom and the default programs can be installed into the internal storage as cab files subsequently
If the above is done the diamond will definitely shines.
I am therefore looking forward to using the touch pro as it comes with 512mb rom and therefore I assume that the free rom storage should be adequate for the user to install a lot of additional programs

Where can one get the updated ROM? I just got my diamond a week ago.. its sluggish at times.. freeze's atleast once every other day.. etc.. I am currently running 1.34.831.1 WWE.
Thank you in advance.

according to the htc helpdesk version 1.37 is not much different from 1.35
it is just a new country rom.

Huh? What's the point of that? Why not just install your user apps to the storage? Besides, installing factory-shipped apps in a user-deletable area is a crazy idea.

This will happen. Why you'd want to waste space installing the optional apps into your precious storage space instead of the spare ROM space intended for that purpose I don't know though...

so you get 256MB (probably actually a lot less, they'll install more) more ROM, and that's better how?

deleting cabs from rom help

i have the sprint stock daimond and i actually like the stock sprint rom except for it was lacking in memory but i was browsing through windows and there are a few cab file that put together take up about 12mb of memory and way to delete them tried with total commander and cannot delete them

Where is all the memory?

Hello all,
I have the Rogers Wireless HTC Touch Diamond, which is advertised with 192 MB RAM, 256 MB ROM and 4 GB internal storage.
When viewing the memory page via Settings-->System (or the drop down menu on the Today screen), it shows total storage memory to be 91.8 MB and total program memory to be 115.0 MB. This doesn't add up to either of the amounts of advertised memory.
I was curious if anyone knows which portion of the memory this information represents - i.e. the RAM or ROM - and where you can find the usage information of the other. I understand the basic concept of RAM vs. ROM, but neither of these figures add up to the advertised 192 MB RAM or 256 MB ROM.
Any help would be greatly appreciated!
Regards,

Rom
All your data is stored in flash and the flash is not erased if your battery runs flat.
This is called persistent storage.
Flash space in the Pocket PC is split between storage and ROM.
The amount of data or programs you install is limited by the amount of free storage (flash) on your device.
Storage in flash is not compressed.
Due to this design, programs that are installed / stored in flash are copied to RAM to be executed - they occupy twice the space.
The directory of data stored in the boot ROM is merged with the storage flash so the user sees the file system as one.
If a file in the boot ROM is replaced by a file in storage flash the storage flash file is used.
RAM
RAM is dedicated to running programs.
If you attempt to run multiple programs that are "hogs", they may not run or the operating system may close some of them.
The memory management for programs flushes pages of programs that are no longer needed, thus optimizing the use of RAM in the system for other programs to execute.
RAM Cache for Flash Storage
A portion of the RAM is used as a write cache to increase the performance of the mobile device when writing to the flash.
This RAM cache is fixed in size by the OEM and the RAM is not usable for any other purpose.
So before performing a soft reset or removing the battery you must turn the unit off and wait 5-10 seconds. If you fail to do this you may corrupt your internal flash storage.

Thanks for the reply, Mike; that's some really good info. However, I still don't understand why my memory page is only accounting for 92 MB (storage) + 115 MB (program) when there's supposed to be 192 MB + 256 MB (as listed in the Diamond specs). Where's the balance? I've attached an image for clarification.
Any insight into this would be much appreciated.
Regards,

Out of the 192MB ram (program), 64MB is dedicated GPU (video) memory. So in fact usable ram is around 128mb.
Out of the 256MB Rom, usually about 80-100mb can be attributed to the ROM image (firmware) of the phone and especially since you're is branded (rogers), there are pre-installed goodies (ya right) that are taking up your space as well.
For your reference my phone shows the following:
Storage
Total: 105.17mb
In Use: 82.54mb
Free: 22.63mb
Program:
Total 107.02mb
In use: 76.67MB
Free: 30.35MB
Keep in mind that i'm on a custom ROM so the numbers will be a little off right off the bat.

Perfect! That's the info I was after. I had a feeling the 'missing' memory was attributed to something like this, but now it's all cleared up.
Thanks again.

Memory for G1

Hello. Sorry for my bad English. I use rom Froyo biffmod v2.01 and I want to ask. This ROM applications stored on the external cache dalvik 4 is so and so does not diminish my phone memory. The 105 applications installed in my phone memory still around 85 MB free. And the question is, is it even something like eclair rom? There I had the same number of applications and the same applications on the phone about 10 megabytes free because of large applications (IGO, copilot), a large part installed into phone memory. I tried the search but unsuccessfully. Thanks for the advice
