nope, the amount of available languages doesn't matter, as there is only one left after initial setup.

i didn't add any language. but when I go to Control Panel->Other->Select language, two items are listed (item1=UK English, item2=American English) and I could select one. |

This is interesting. The first time I heard of a P990 not made in France.
P990i: A mistake, a curse and a disgrace  So I lowered my expectations and settled for a P1i. I couldn't keep my expectations so low for a long time so now I have an HTC Touch HD |

I'm not sure about that. In an earlier fw version, first I had set up my P990 to use Turkish, several weeks later I changed it to UK English without downloading anything.
I don't know if the files are the same but with this latest fw I am using UK English but I'm able to select Turkish as my primary T9 (or whatever the equivalent is) language.

so what's in ROM now?
Why it's not consistent across CDAs? |

@makbil
So we can conclude that we get UK English, regardless if selected or not.
If we select UK English, we get UK English only, and if we select any other language, say Turkish, we get both, UK English + Turkish.
Interesting, didn't know that.
Well, this also proves that the amount of installed languages does not affect the ram/rom ratio, as I have only one language and still 59/5.
And then, aren't the additional languages being stored in c: anyway ?

Here is some more detailed info on the ROM issue:
- SMP uses standard system calls to retrieve the two values that it displays as "RAM total" and "ROM size", respectively.
- The sum of the above two values equals to the RAM chip's total size, as given in the phone documentation. The sum is 128 MB for P1 and W960, and 64 MB for all other current UIQ3 phones (including Z8).
- The value of "RAM total" is widely used by programs as the total amount of runtime memory (where all programs are kept while running), like when calculating the percentage of available free memory.
- "ROM size" is rarely used by programs, its exact meaning is undocumented and remains uncertain.
- The "ROM size" can be between 2 and 5 MB, depending on phone model. As an extreme value, it is 14 MB on our prototype Z8. It also seems to differ between certain hardware and firmware versions within the same phone model.
- "ROM size" does not represent the size of read-only memory in the classical sense. True ROM is where the firmware resides, that is the Z: drive of the phone, whose contents occupy much more space than 2 to 5 MB.
So what exactly is the memory area represented by the "ROM size" value? We don't know. Our best guess is that it is an area of RAM that is not used by ordinary programs, not even by most parts of the OS, but instead may be reserved for a limited range of system components that are always loaded and specially treated. The available documentation calls it ROM, but this looks plain misleading.
And, why does its value vary between phones? We know that even less. What really counts is the absolute (not percentage!) amount of free available RAM. It would be interesting to see if a firmware change, that results in a change of the "ROM size", results in a change of available RAM, under the very same conditions.

Lisa, you seem to be on the right track according to this info:
http://my-symbian.info/forum/viewtopic.php?p=290852#290852 (follow the discussion some posts from there)
and
http://my-symbian.com/forum/viewtopic.php?p=284939#284939 (linked to from a post in the thread above)
To summarize: The "ROM size" value seems to be the CoreOS part (seems to be the Symbian kernel among other stuff) of the firmware, which is permanently loaded into the RAM (while other apps get loaded into RAM when they are used).
This explains why "ROM" + RAM = 64 MB, and the reason why it changes between firmware versions might be that more stuff is classified as CoreOS for some unknown reasons. I guess that some of the hidden tasks shown in SMP (when "show hidden tasks" is enabled) are parts of the CoreOS. In any case, the "Phone" app is probably part of the CoreOS, since a smartphone with no phone functionality left is not a phone anymore, it's just a PDA... That's probably the reason why it can't be closed down.

Thanks @firetech. Quoted from the second thread linked above:
('real') ROM, which contains the most essential parts of the firmware ... and which is permanently copied to RAM ('shadowed').
Most probably the fixed amount of the above-mentioned shadow RAM is what SMP reports as "ROM size".

I think all the languages remain on the P990 unless you do a format. When I was setting up my phone, I just chose UK English, nowhere did I specify Turkish anywhere. Later on, after the setup was finished, I was able to add the Turkish language for writing SMS etc.

Yes, the language support for T9, letters and virtual keyboard remains, even after format, but the menu languages are being deleted during initial setup.
Otherwise they would appear in the list of available languages.

guys, I have 61MB Nand
and drive Z: is Total Space 0,0MB
impossible?
edit: I remember that I did a master reset right after the reflash of R6E28, then I selected UK English, after that all other languages where gone. I had about 59MB of the 61MB free!!

guys, I have 61MB Nand and drive Z: is Total Space 0,0MB You are making even bigger confusion  This thread is not about the size of the C: (Nand) and Z: drives, but instead about RAM, which is entirely different. You should look into the Memory dialog of SMP, not the Drives dialog.
BTW, the size of the Z: drive is surely not 0.0 MB, but the OS reports that value for a ROM drive, so SMP displays that. The correct value can be obtained by adding the sizes of individual directories on the Z: drive.
