confused about mem alloc. in wm2k5

hi there,
i've been looking for info. about upgrading himalaya to wm2k5 on this forum for days and i found there are several versions of the wm2k5 rom.
does it mean that wm2005 has NO memory (RAM) allocation setting so the amout of memory used to run programs is decided ONLY by (thus cannot be changed like wm2k3) the ROM being used?
but what if someone on 128Mb version found his 30M storage is not enough and he wants a 32M ramdisk?
the only way change it is to re-flash a different rom and hard-reset the device?

You got it right both times.
You did a good research job.

Roms, hard resets and windows mobile.

Hi, I'm looking for more info on how the memory is partitioned between storage and programs. I don't quite understand how a hard reset is equivalent to a reinstall, and how it works.
Is there a site or book with more information on this? Any help or pointer would be greatly appreciated!

a pocketpc have ram and rom
rom is read only memory
the os is located in rom
and storage and application memory is in ram
how much you want to have free for application ram
and how much you want to use as storage is up to you using the memory slider
a hardreset or too long without batt
clear the ram leaving the os which is in rom
as the only thing on the pocketpc
which is why it's the same thing as a reinstall
because all the stuff you put on it are gon
leaving what the maker of the device put in the rom
but with 2005 things have changed a bit
here some of the flash rom is used for storage
and all ram is used for application memory
(though buzz and the lads made it so some of the ram can be used for stroage on older HTC devices which otherwise only have 32MB)
here a hardreset dont mean a reinstall
if you want to clear the device to default you have to format
the storage from inside the bootloader

I think what he meant is the one shown in "Settings"->"Memory"->"Main"
Think of the "Storage" as the hardisk of your PC and "Program" as the RAM of your PC. For WM5, when you soft reset your unit, the "Program" memory will be cleared off and program will be loaded again into this "Program" memory.
As for the "Storage", it is the `hardisk` where you have your OS installed. The OS is kept in the ROM (which I don't think is part of the "Storage"), and it is installed into your "Storage" everytime you perform a hard reset. (e.g. the "Storage" will be wipe clearn upon a hard reset). Anything that you do, e.g. edit file, add contact, etc. will be recorded/saved into this "Storage".

Thanks for the replies. So what I see when I browse the device, including the 'windows' folder, that's a copy of the operating system, and the original master copy is in the ROM?
So theoretically, I could go and delete the whole windows folder, perform a hard reset, and everything would be fine?
Has anyone already tried to see what could be reasonnably removed from the windows folder in order save 'storage' space?
Cheers!

no whats in the windows dir is the os which is stored in the rom
you cant remove things in the rom

I'll reply to my own question in order to close this thread and make it useful to others:
(from pocketpcdubai)
The Universal comes with 128MB ROM and 64MB RAM as compared to its predecessors who had the exact opposite.
The 128MB ROM is divided into 2 parts:
1) OS + Extended ROM (around 84MB)
2) Storage (remaining 43.5MB as shown above

I am sure this question has been asked somewhere in this forum, trust me I have searched alot before posting this question here, the only reason that I am asking this question because there are so many threads and so many pages to it. I am confused like anything.
i installed wm2005 after a long long time.
installed Rom Version : 2.01a00
when i click on memory it shows 120 and storage shows 14 something mb's
my device is XDA II, which as far as i know has 128 + 32 for rom + 32 for storage (please correct me if am wrong)
is there a way to increase 14mb storage ?
when i install Ramdisk i get 64mb more, where does that come from ?
when i install extended rom unlocker i get another chunk of mb, dont remember the size. where does all this come from ? the 128 mb i mentioned above, or is this hidden and the mentioned tools make it available ? and how can 14mb storage be increased for program installations.
a quick response would really be appreciated.
jeetz..

ramdisk is ram and is taken from the 128MB application ram

and secondly storage is showing 14 something mb's, when ever i try to install a program xda II gets frozen up and i get an error message saying critical low memory, so where's all that 128 mb gone ? and how can i install programs with out freezing up the pda.
thanks rudegar for an early reply.

install them on the ramdisk

my RAMDISK lost, why?

I cook my own ROM of Hima WM5, based on llsbasha and C_Shekhar.
after several times, I decide using 64M program, 32M RAMDISK, 32M PagePool. At First, I success, but the second time, when I open memory from Start --> Settings, my Hima says no storage cards (my sd card ejected)
RAMDISK DISAPPEARED
How can I find it back?

I don't know what happened to your storage card but I think I know for the ramdisk.
Well, I suggest that you hard reset your xdaII and do not install ramdisk software to increase ramdisk size. Based on my experience, after I installed the ramdisk 64, the size increased to 90+ but everytime I soft reset, the data I saved in it gets lost.
After hard resetting, the ramdisk came back to normal 30+, I found the lost previous data intact though.

Can you list out the steps you are taking for the configuration you are trying to finalize? Because if you change the configuration after flashing the ROM (or on a working ROM) the settings are likely to disappaer after soft-reset).

This will only happen if your battery are old and need to change.. Some how it will not keep the RAMdisk and only by another flash will bring it back.

storage problem. help pls

i upgraded my himalaya with wm5 helmis rom. my problem is its storage capacity. it only has 14 mb of storage. how am i going to extend its storage. is there any procedure for doing this? thanks.

http://www.buzzdev.net/index.php?option=com_remository&Itemid=132&func=fileinfo&id=125
or use another rom with more storage

i have the exact problem...16MB storage...always have 0.6MB free...can't install software...
tried to reduce the RAMDISK to 32 MB, program is increased, storage the same...

storage cant be inc it's flashrom and cant use the normal ram
but one can just install programs on RAMDISK it's faster then normal storage anyway it being ram (well ½ of it) and storage is flash

Use HIMA_DOC_TOOL v1.0 to increase the storage from 15 MB to 30 MB. Search the forum.

Thanks c_shekhar for your response. I searched around the forum, seems this extrom unlock has been discussed for years.
for my understand, need to run the ExtROM Tools to unhide/unlock extrom, then run the Hima_DOC_Tool_1.0 to merge storage and extrom. Now here is the question, I unhide the extrom successfully, can see it for 15.97MB, however the unlock does not work, it has the "blue square" icon and fails "Either it is not signed with a trustred certificate, or one of its components cannot be found".
Not sure this is a corrupted package or something missing from my ROM, the .rar opens fine, but the winrar reports .cab file is corrupted when trying to open it.
My ROM is 3.50c.40CS version...appreciate for your time to help!

Excellent, found the solution from buzz forum...i installed the unlocker to SD card that is why it faied...after re-installing to DEVICE, it works!!! got 30.5MB storage, very happy. Thanks guys.
