Hi i have downloaded windows 7 rc and there you have a nice option to use your usb stick for gaining extra RAM for boosting up your system
My question is is it possible to take an amount of an sd card like 8gb , like 1gb of it for giving this space for the device for using as RAM?
At my opinion flash cards are fast enough to do this job
Sry for my english
Read this:

But i dont know how that works exactly how can i find the boot.rgu file and what is a XIP?
i dont know anything about programation what i have to do exactly?
Does it exist an tutorial for this?

I'm trying to get expert answer what should be the right way to partition sd card of 8gb class 4 for mt3g 32b. Some developers are saying that fat32 is good enough, some are saying that we need ext 3 and swap, some are saying that swap slows down the performance ? I'm just not sure what is the right way ?

Depends what Rom you running, really. Linux wise, an Ext bigger than 1GB is a waste. i dont think the OS can use more than that. 512 is adequate. As far as swap, unless you are using a Rom that takes use of it or run a script to implement it. Its was a waste as well. As far as ext3 to ext4, i would recommend googling it or looking it up on wikipedia. I currently use ext4 with the cyanogen roms since i read that is the way he has his dev phone set up.
I was using "search" to find similar question but i didnt found anything.
My question is :
So far the biggest problem with battery , and android speed was related
with using SD Card.
Ok . I'm a NOOB with Android so don't laugh please :
Is there a way to build WM Rom with smallest number of files
to make device bootable and implement into this Android files ?
I know ... Android is building a BIG folder ( aprox. 700 MB ).
But if we could keep only most important system files
inside the rom , and all the rest will be kept on memory card ???
What you think ?
Is it possible ?
It could save battery , mayby more speed - only if it possible
??????
Still learning - sorry for bad EN.

There are no drivers for the NAND as far as I know. That is why there is SD boot. Go to a file explorer in android and there is no nand partition or folder in the root alongside 'sdcard'
so from what i understand, we need windows booted to power up all the hardware. correct?
i think what he was asking and i was asking earlier is:
if we build a minimal windows boot, ONLY to power up the hardware, and then move the "android" folder from memory card to main phone memory and create the launcher to start the haret and the other file from the phone memory just like it would start from SD card.
in other words treat the phone memory like a SD card am i missing something?

That is right !!!
But not to move everything from catalogue Android from SD card to phone memory.
Only most necessary files like drivers, kernel and such.
Files that could keep battery lives longer on stanby with good system stability.
If not possible...... maybe your way will be better ...if possible.
well to split the filesystem between main memory and sd card you have to change alot of file refferences and links its gonna be a nightmaire.
but i dont know enough about this system to tell if this could work or not
[Q]What's the different between (512Mb & 1Gb) data file running Android from sdCard??
Good day everybody,
I just want to know [Q]What's the different between (512Mb & 1Gb) data file running Android from sdCard??
because I'm having problems with running the MDJ FroYo HD v.4.6 in 512 Mbyte HTC HD2 version, such as;
- freezing
- slow movement while browsing the menu
- can't access the Market where it always saying that the username or password is wrong
while the same Android ROM is running smoothly on the T-Mobile HD2 version without any single problem and very fast.
both phones, the T-Mobile HD2 version and the HTC HD2 512Mbyte version are updated to the latest Radio (2.15.50.14) and Microsoft Windows 6.5 ROM (3.14.531.1)
any hints??
512Mb & 1Gb data files are simply the amount of space u'll be taking off d sd card for android apps & data installations...So d bigger,d more space you'll have for your android and less space on your sd card for things like music, ebooks, images etc...
IMHO....1GB & above is highly recommended so u don't have low memory issues after tossing android on your sd card..This is cuz u might end up needing more apps & some apps lyk high-end games do tk up a lot of space.
As for speed differences between the two Leos...Well d TMobile Hd2's more buffed up and so..........U might want 2 try lighter android builds cuz d HD versions are some what heavier....Also your choice of Memory card class & capacity also helps...i'd recommend an 8GB Class (4)...
The Data.img isnt your problem anyway your problem is that you are trying to use a very old and outdated rom that was never very good to begin with

hi
what kernel do you use?
try the hastarin 8.6 kernel. i used to have similar problems (i mean laggy phone) and the kernel kind of sorted it out (i use the same android build as you do). maybe it'll help you (i don't know if it's gonna help market problem but i think 'freezing' might be cured)

Thanks for the reply, so does it mean that I will have only a 1 GB in the sdCard dedicated for Android and all applications from the market???
I mean if I move the apps & games I downloaded from market to the sdCard using the Manage Applications under setting menu, will it make any diffrence???
Thanks

Thsnks for the reply, but it's not helping as I said in the first post
" I'm running the same version of this ROM in more than one T-Mobile HD2s and all of them run very smoothly without any problems"
Then how it works in the T-mobile smootly but not in the 512Mbyte version ???

Aha, here we go somebody with the same problem
Yes it might be the kernal, the kernal in the phone shows these lines:
2.6.32.15.s8.0-gf06973d-dirty
[email protected]#10
Mon Dec 13 17:53:37 KART 2010
And I do remember that when I un-rar the ROM file, there was a kernal folder but I didn't use it because I don't know how!!!
Whould you please upload me the kernal you're using or give me the link you download it from??
Would some tell me how to install the new kernal ???
Regarding the Market issue, just don't worry about it " I was entering the wrong pass " Many thanks

Swap the SD cards between the phones and try again.
If it follows the SD Card (and you're sure the setup is EXACTLY the same) it's your SD
It could be a bad SD or you may just have to delete/recreate the partition and format it.
Your phone are also different. I'm not sure it's just the mem size, some chip could be differents, drivers...

Yes u'll have only 1GB dedicated to android and all apps...By this i mean it'll show up as available "phone" memory (just think of it as a virtual drive but in reality it takes physical space 4rom ur sd card)...I.e..using an 8GB mem card? Phone storage will read 1024MB while SD storage will read abt 6.xxGB...
Yes, if u move apps 2 sd it'll mk a difference but i think 1Gb is enuf for apps and u don't really need 2 move apps 2 "sd" storage as it might cuz slight speed issues since u r running android from d "same" mem card.

here it is. try the 8.6 (that's the one i'm using).
to install it on your phone:
unpack it
find the zImage file
copy it into android folder
find the root folder from the kernel zip
place the folder onto android
reboot
delete the root folder you pasted

As The Title Suggests, Is There Any Way To Install A ROM Onto A 16GB MicrSDHC (class 10) Instead Of The Phones Internal Memory?
I 'Googled" It For Several Hours, Unfortunately Did Not Find An Answer.
Let Me Explain Further As To What I'm Really Trying To Accomplish. I Want To Flash A(ny) ROM Onto The MicroSD Card So I Will Have The Entire Internal Memory Free On My G1. And Then (if at all possible) Somehow Use The Internal Storage As Extended RAM.
Even If This Seems "Close To Impossible", Could Someone With Enough Knowledge (a dev?) Explain How Something Like This "Could" Be Accomplished??
Thanks For Your Time! Can't Wait To Read What People Have To Say About This..
Ideas & Possible Solutions Are Better Than Just Saying 'It Can't Be Done..etc'
As for installing a rom onto sdcard (even on ext2 partition as it is being done on the HTC Fuze/Diamond/Topaz/etc windows series phones), it is completely possible, but it is very slow.. i don't see why you would want to do that even compared to NAND install if you have lots of ram
I used to be a developer for the HTC Fuze (Touch Pro) and made a 2.2 aosp SD-ext rom, it still isn't as fast as the G1 even though it has slightly higher specs: 288 ram, msm7201a (same cpu as htc dream)..
You can't extend the RAM, but you can make it swapspace. It would kill the internal memory very quickly because it is only yaffs and has a limited number of read and writes...

Google Android rom's or Operating systems have rules and limits, I do know androids 2.2 did not allow system files to run outside /system folder, now it's allowing more as you see lot's of rom's using /ext (linux partitions) I do not know all the limits, but do believe there has to be a part of the rom in internel memory to be able to boot sd-card
So i have a list of stuff that i couldn't do so im seeking ur guys help !!!
1. How to use more than 445 mb of system size when partitioning ...
i use magldr 1.1.3 and when i flash TWRP i modify the flash.cfg file and i write for example
500 mb in system and 10 mb for recovery and 44 mb for cache
...what do i need to do use more than that i always use [datatoext] so i really don't use the onboard nand
correct me if im wrong but its only used for system date and cache right ... or is cache take a part in the ram nand
2. what ever rom i use it always shows 410 mb of ram will im using a 1042 rom / 576 ram t-mobile HTC HD2 with
t-mous radio version 15.42.50.11U_2.15.50.14 so is it right or is there missing ram ..
3. I have used a lot of roms like each pixilfreak rom ,parnoid android , slim rom , miui roms ,aokp roms
and i have 120 / 130 mb ram usage with custom launchers like adw , nova ,apex .. good right !!
4. How do i know for sure that the 200mb swap partition that i created is being used ...
.. and then an of subject question i have a nokia lumia 920 so is wp on the hd2 any where close to that i know that the difference is like
moon and sun but i just want a couple of views cause i want to try wp 7 on the hd2 but i don't like one bit of it ..
and the 920 i gave to my sis just so u know *
1- 445mb is maximum for any hd2 (eu or tmous) afaik, never seen someone using more on tmous so i don't think it's possible
2- it's 576mb ram, but android shows 410 because parts of it are for video memory (128mb i think) and the rest is for system/kernel etc so you can use 410mb
3- is 3 a question?
4- that depends whether you created the partition correctly, and if the rom SUPPORTS swap (it should be an option in installer)

thanks man for the fast repely this were just stuff going thru my mind that i wanted to clear ..
any how the swap partition is right because i use lubuntu linux as my main computer system
and i have a swap on that and also i have partitioned my sdcard with the gparted app .
i just wanted to know if there is a tool to monitor swap usage in android :cyclops::cyclops:

well i don't know about that
but there are 2 commands, swapon and swapoff in terminal emulator which you can use but they need linux knowledge and i never used them before so try google-ing for what you want to know

your phone is using the onboard nand constantly, since that is where the system is running from.
Re:swap - personally i only use roms that either don't offer swap, or have the ability to choose not to activate it. The (usually very small) performance gain is hugely outweighed to my mind by the increased load/decreased life of the sd card.
