Therefore if we install to /SDCARD or even the whole OS keep running it from the SDCARD we will have all this free memory for the OS...correct?

You're making my brain hurt... I don't know what you're trying to ask, and I think you might be using the wrong terms.

RAM is volatile. It is wiped every time you shutdown your phone (or computer).

ROM is where the WinMo OS is stored. We're trying to get Android to take over this portion, so WinMo would no longer be required on our phones - we could run pure Android.

I'm still not sure if that answered your question.

Yep. So what memory does the OS use when we install programs? (For example, APK's, will it take up RAM therefore giving less RAM to the OS? The OS needs memory to run software as well to store them, computers have hard drives where programs get stored and when you run the program it gets moved to RAM.

Ok, lets see it this way... When you use ADVANCED TASK KILLER you have a FREE MEMORY that gets decreased when you have a WM ROM installed on the phone, also when you install APK's this memory starts decreasing....! So if we keep the OS and installed apps on SDCARD we will have all this RAM available for the OS, correct?

I think you're mixing up RAM and ROM. Let's stick with Android for this example - anything we install it will take up memory on the SD card. Any app that's RUNNING will take up RAM. RAM is used by everything - it's a placeholder for information between the processor and disk.

So Advanced Task Killer will free up RAM when you kill apps. If you remove the app from your phone, you free up space on the SD card.

Make sense? This is all pretty OT too dude... I'm not sure where you should ask these questions either tho lol.

Do you know how to compile the kernel ? it would be great if more people were able to compile it and test it. I'm still trying to finalize the battery changes so we have more accurate readings. After that i'll probably venture into the panel light staying on issue. Thats killing power like no other so it needs to be looked into.

I may need to go back to wince to look into the 3d issue. Unless someone wants to start dumping memory off haret .. so much to do ..

I've compiled linux kernels in the past, though I have yet to do one for Andriod. Let me run through this and see if I have the right process, and maybe give me a refresher.

I'm cloning git://gitorious.org/linux-on-qualcomm-s-msm/linux-msm.git
Then checkout htc-msm origin/htc-msm
Then make defconfig (What defconfig are we using?)
Then clean
Then cross compile zImage (What is the path to the toolchain we are using?)

Do we care about cleaning compiled files and rebuilding from scratch? I've got a Core i7 930 machine with a Vertex 2 SSD to crunch this on. I'm totally willing to help. Just need specifics

I know that part, now that we have the OS on the SDCARD and we install software it goes to SDCARD, but what about when we install software on Windows Mobile, where is our "hard drive" for the phone? If RAM gets wiped out when we power-cycle the device, where are these programs getting installed at? I install to "DEVICE" not "SDCARD" so there must be some "memory" that doesn't get wiped out on power-cycle....

Yeah, I think the easiest way to explain this for him is to compare it to a computer. The internal NAND is like a hard drive, the microSD is like an external drive, and the RAM is like System Memory. Currently, Android is running off the microSD card and does not access the NAND.

Your RAM is not a storage component and does not decrease based on the amount of things you have installed. When you launch an application, it loads itself into RAM as needed. If you launch of ton of applications, they will all stay loaded in RAM, but Android unloads parts of the applications from memory as needed. Do not use a Task Killer in Android 2.2 as you are preventing Android from doing its job in managing your RAM.

Think of the SD card as an external hard drive. In Windows, you install applications to the internal hard drive. Android is running off the external hard drive and cannot access the internal hard drive. All applications are installed to the external hard drive with Android.

Also, if any mods can come along and move this crap into a new thread, that would be great.

WinMo has nothing to do with this topic, so I'm done responding to these OT posts... Sorry for dragging it out so long mods! If a mod could break this out into another thread that's not in Android Dev, I'd be happy to continue talking to you about it.

[m4f1050]

It has nothing to do with WinMo I was using it as comparison. I thought we had RAM, FLASH and SDCARD...

Ok, so the NAND is our harddrive, which holds the ANDROID (os) and installed programs.

The ANDROID and installed programs load into RAM from the NAND (harddrive)

What I don't understand is when we flash the phone with a small ROM on NAND why does our available RAM increase in ANDROID? Do we "partition" these 2 different sections of memory?

Holy f*ck...
