Okay before anyone starts to flame or start saying "Oh God" to the screen, this isnt the typical "When are we going to get Android to boot from HD2" question.
I know we all boot Android from our SDCard, but I went looking to see if there was any google pages on why the sd card? Being that we have an HD2 and it has alot of space (My phone says 768mb free internal storage), would it slow Android and the experience down if we had the "Android" folder copied to our phone instead? I know currently it probably wouldnt work, but being that the avg Android folder is 230mb to 260mb thats more then enough space to put the folder in, and possibly change maybe the daily useage or app installations onto the sdcard. If this was just a general rule of thumb that it was decided to be put on an sdcard across the board because not all phone had the room then is there no way to change that now since most phones are coming out to have larger internal space opposed to older ones?
And again, would it be slower to run this way or not?

hi
Haret cannot currently read from NAND, its code reads and searches for Data IMG and Rootfs and kernal in SD ONLY .....
hence NAND is so very different from HARET.
well Magldr is what would do the trick
I'm assuming your talking about nand as to boot from the phone like as if you are powering it up and windows loads, Im not actually talking about that. I'm actually talking about how it currently loads, except, instead of placing the Android folder on the SDCard and running clrcad and haret, instead placing the folder into the root directory of the phone and running clrcad and haret from there, same exact way we are running it now, except changing the location of the folder from card to phone.

hi
Well firstly NAND does not necessarly mean booting from start, NAND= Internal memory, in fact cotulla's MAGLDR can boot android of the SD straight from power up whilst having WIN MO on NAND.
So to answer your question again,
HARET CANNOT READ NAND (INTERNAL MEMORY), it always looks for SD for everything , in some cases RAM, as in the new RAM builds that are popping up by devs.
the code for HARET cannot handle NAND at the moment and i dont thing it will ever be implemented.
I'm neither a dev or a hacker, this is just what i ahve understood from reading, i'm open to corrections,
best regds
I have to admit, this idea is very cool.. If haret could "see" the nand memory after WinMo is loaded, then all you need is a WinMo rom stripped down to the maximum and Android folder burned in it (at least the system part). if if if i am not sure, if its technicaly impossible for haret to see the nand memory after booting WinMo or if its impossible at all..

guys remeber HARET is a bootloader for LINUX, its crazy enough its helping us boot android from SD, I think the possible reason HARET is not designed for reading NAND is the potential damage it could do to SPL leading to a BRICK, now we dont want a brick do we ?

never say never and expect the unexpected, thats what life teached me
phone wouldnt get bricked if you just read nand, but writing into it could do damage, i agree on this.
OK, so when I first read the OP, I thought he meant booting Haret from the phone's internal storage memory, not NAND.
Though the NAND Haret idea is really not bad, I couldn't see it corrupting the bootloader as long as it behaves the same way as it does from the sd. I mean, the phone is already booted WinMo, so HaRet and Android have no need to touch the bootloader, just as when running from sd. It would be more or less a startup.txt change/ rel_path = NAND/Android (not exact, but general idea). Seems alot different to me from MAGLDR, maybe there is just confusion about this
But if the NAND idea is not workable, wouldn't it be possible to run HaRet Android from the phone's internal storage memory, yielding a performance speed increase and less wear on the sd?
Clearly we couldn't do like I have now, a ton of builds with exceller, all running from internal storage, obviously we don't have 16gb internal. But what about just loading our daily driver from internal, and testing/less commonly builds from sd?
I like the idea because it could mean less wear on the sd, and possibly performance increase
BTW 300th post
Thats exactly what I meant, once WinMo is loaded, we normally go into the sd card thru file explorer and then go to android and then run clrcad and haret, winMo is already loaded and doesnt corrupt winmo, but if we could run the core system from the phones storage space, (Putting the android folder into the main directory, and then running clrcad and haret, this way the core system would load and any user installable files would just end up on the storage card, cause obviously we wouldnt be able to load all our apks into the phone (Some might, others like us go nuts).
But the concept is not a bad one, especially if there was a way when installing the apk's it asked for the location to add.

I would say that if HaRet was pointed to the correct place correspondingly, either NAND or storage would work as I previously mentioned. I am unsure about any performance gains to be had, but it would surely save on sd card wear.
People say that going from NAND would corrupt bootloader, but since WM is already booted using HaRet, there is no reason that the bootloader is touched, even if it is all stored to NAND. MagLDR is different, that is going for a cold-boot of Android, no WM involved at all. HaRet and MAGLDR work different and I think that if Haret was made to look for /Android in NAND, it could work just the same as if off of sdcard.
And booting from the phone's storage memory would be even safer, as no far-fetched idea of HaRet corrupting the bootloader is even conceivable, as NAND would never even be touched at all.
I honestly believe though that if a version of Haret was released that looked to NAND memory for /Android, that WM chefs could bake lite version WM ROMs with popular Android builds already built into NAND, maybe in the \Windows directory. The chef could even cook in a modified version of Exceller's Android loader which would look to \Windows for the Android folder.
Since Android development is so far along, and there are so many builds that are 100% or near 100% stable, I do think that going this route is a viable option, I mean there are already WM builds that will install an Android build to the sd card all by themselves after you boot them up the first time. This seems a natural progression of that concept to me.
Maybe somebody could contact Netripper, and ask him more about this idea, and see if he would be kind enough to build a HaRet version to look to NaND memory, and another to look to internal storage space, the rest could be done by the end user, as there are WM kitchens available, and most ppl here could make a .cab to install \Android to internal.
That's my $0.02

Very possible,
Haret needs to be modified for that,
not sure who can do it.
Guys as far as i know, on hd2 is nand memory the same as internal phone memory.There is no built in sd card. I am not 100% sure, but there is 512mb nand memory (internal memory). I mean, we install winmo roms into the nand. So if your winmo rom is about 200mb, you will be left with soemthing like 300mb internal phone memory. Correct me, if i am wrong..

Well true except the TMOUS, which is 1024 mb, so it should be plenty then to run Android this way right?
Even with just 300 left after WM ROM, Android could still be done conservatively, without much apps installed, or with some kind of a2sd functionality, Froyo has inbuilt app to sd functionality, albeit not as good as a2sd ext2 or ext3 setup.
Guys I think you are missing the point, If this was possible, viable or worth it, it would have probably already been tried and tested and released along time ago.
The fact that this hasnt been done already tells me that its been thought about and rejected for good reason.
PS. NAND ..IS.. Internal memory guys so the running loading of kernel and files from internel memory instead of nand is a moot point.
Here's a question for you guys thinking it *could* be possible to put Android on internal storage(NOT NAND) instead of SD...
What do you think will happen after your device creates the data.img and tries to place it in the Android folder on Internal Storage? I for one think my device(1024 TMOUS Leo) would run out of memory and throw error after error about internal storage being critically low until I did something about it.
To top it off, what about the 100 some odd folders that Android creates on the SD card now? Where are you going to put all of that on internal storage?
To sum it all up folks, until we're running from nand and have dedicated internal storage(W/O WM), it's not likely to EVER happen due to sheer lack of space, even if haret was reprogrammed to allow booting from internal storage.

well in that case, kernel could be programed to create Data IMG on SD, if you have been following the Rhodium Nand Project , you will see what i mean, a few components are on NAND and a few on SD

Its not about putting the whole Android folder into nand, but for example only the system partition, just like in the RAM builds. All data and user stuff goes to sd.
Btw what do you mean by "...*could* be possible to put Android on internal storage(NOT NAND)." ? nand is the internal storage (memory). Or you guys are using different terms do you mean by "nand" the reseverd space where roms are stored and by "internal storage" the free space left (still in nand)?

Actually your part right, it was tested and released in the initial phases of the Rapheal (aka Fuze) and ran smoothly from what I read, yes there were hiccups, but that was due to the build being still in the alpha stages.

This is where your part wrong as well. if you use a pre-set data.img file, yes for the most part you cant use anything larger then possibly 512mb on a TMous, 256 on others, definitely could not use the 1gb img file thats for sure, but the other part of this your missing is that if you dont put a pre-set data.img file, during the initial loading of android, android will create the file itself, and IF I am right the file will be sort of dynamic, dynamic in the sense it will expand as needed, I seriously doubt it shrinks. And on top of this you would then use the function a2sd, which in then would install your apk's to sd card. As of right now how much bigger is your 1gb data.img file that everyone added to their SDCards? Bet still the same size.

Actually after doing some reading, neither the kernel (if I read correctly) nor is haret.exe the cause of pointing the boot location. I did some searching (Mind you I am NOT a LINUX person), but reading some of the files, I am guessing that the key file which controls the loading of Android, is located in the "init" file in the rootfs.img file. I mounted this file in windows to look thru it and view files, and that file seems to have a major role in it, how it works I dont know yet.
To All, please I am not trying to cause a stir here, I am merely looking at possibilities, and unfortunately I cant test them out since I dont have a spare SDCard as of yet (Will ina couple of days, 32GB SDCard for $40, woohoo), and then I have nothing to loose to try, cant brick the phone, since winmo is the default loading OS anyway. One of the reason it might not have been put on the phone as I said, could be speed, I dont know how much faster internal phone storage would be opposed to sd, but another reason why could be cause then the installation would put folders on the root file system of the stroage card and make it messy. Also alot of people constantly flash new builds, this would also hamper your android install being on the phones storage. And remember our normal HD2 roms are between 225 and 250mb stock or custom, where lite versions or stripped down version would be considered better for taking up less space.
One thing to keep note, during all this, I have an HTC Aria (Liberty) as well that I just recently got as an upgrade to one of my ATT lines, and I checked the internal storage of that phone, its stock with ATT's build of Android, and it has ONLY 168mb of storage available, and it came with a 2gb sd card. Now think about that when saying that the files would get to big, obviously the HTC Aria doesnt have anywhere near the capacity of the HD2.
And again to anyone else, let's be clear, yes the phones storage is a NAND, but just to make clear, we aren't talking about doing a cold boot of android, I know how sometimes that can get confusing.
Sorry guys, yes internal storage is NAND memory, the reason I drew a distinction was to make a distinction between loading from internal storage and ROM space. I only meant to illustrate the difference between the two and demonstrate my opinion that both are possible. I think with further investigation and testing, advantages of booting this way will begin to emerge. For example we will be able to remove the sd card while Android runs, not a great benifit, but you get the idea. But yeah, I should have used the term 'ROM Space' instead of NAND, I only meant to show difference between the 2 places to boot from.
Sorry if i caused any confusion.

Title says it all
I am wondering that question as well..., how do you access the data/files on ya SD inside Android/NAND Android?
Well there's always file managing apps like Astro, but I'm not sure if it works that way, so, if someone could put kill our question!
Android is Linux based so there should be a similiar command to ls -a where you can see the files and be able to run SD Roms? Or I'm kinda hoping there is..., in SU maybe???
Thanks for the feedback bro, appreciate them.
We just need a response from actual experience; surely trying to run Android off SD wouldn't harm the device in any way.
I don't think we can boot an android build from an android build seeing as how clrcad and haret was build for winmo. >.> but looking at the magdlr notes, if i'm wrong, it has an option to boot android from SD or to boot from NAND, so guess that means you can have an android build in SD and NAND.
NEVER MIND... it failed the second time.
Yes but the build has to be built like a nand build. So you can't just boot the ones you have now.

I just tried..., I done what I would normally do for an SD Build and used the NAND boot menu to try to run the SD Build. Even though there is an option which says you can run from AD SD..., it doesn't happen.
http://forum.xda-developers.com/showpost.php?p=10202441&postcount=146 <-- This makes sense ( no pun intended )
I understand that a Nand build on SD card will work the same as Nand build on phone, that makes perfect sense.
Question is, is the SD card memory used for application files or will it use up all the memory on my phone like Nand on phone does? Is it possible to use a data.img. Of course, the perfect solution would be to add the option in Magldr (Nand) to boot into recovery so the SD card could be partitioned for files and ext3 for extra application system files like we can with a normal Android phone. Then the need to add another Android rom onto the SD card just for extra storage would not be needed for us European users.
Sent from my HTC HD2 using XDA App
besides apps, is there anything else stored in the internal storage? i just got android on my HD2 and got everything set up, and i really don't feel like formatting my sd for a2sd, and i won't need too much space for apps.
also, is there a way to install apps on the sd without formatting anything? thanks.
System stuff, like the system.img from the android build you downloaded, uhh cache, HSPL/SPL, MAGLDR (This is if you're using a NAND android build). Mhm, pretty much that? Note even if you delete some system stuff it won't really free of storage for apps, as the memory is partitioned (meaning that it has a set amount of available space for apps, etc, and a set amount for system).
Well you could use the the freed system data for apps, just navigate to /system/apps and copy your apks to there. You can use droid or root explorer, or any explorer that has access to the roots of your device.
You can try move2sd, but it doesn't completely install the app to sd, it just moves a big chunk of the app to sd, leaving some left in the phone.
huh, seems like moving to sd will work for stuff like Astro File Manager but not system stuff PowerAmp. gonna try games if i can get them to download from the market.
have another question. is it possible for WP7 to load from the SD and boot from android, preferably without deleting the contents of the sd? i can't deal with magldr because of my touch screen problems. whenever i use the end key, my touch screen could start freezing, and i've set up android so that i never have to use the end key.

WP7 needs to be installed on NAND with magldr. You can run android off SD,then. Thats the only way to dualboot.
