Yes what? Wm, will be totally removed from ram. It will startup linux as kernel 
with android as mobile OS. I can remember a dev was talking about not being 
able to free all available ram....

No, you are wrong. There is no emulation at all, Windows Mobile is fully 
removed from RAM memory, and the Linux kernel and Android replace it. The only 
reason why a part of the RAM seems missing is because it is being shared with 
hardware parts.

"LOST" ram is reserved for videocard chip and other hardware.
I don't think that it can be used safely, even if you can "unlock" it.

Are you sure about this, or do you think that?

Changed title: other: less ram in android (158MB/256MB)

GoogleCodeExporter commented 8 years ago

64 mb - radio (radio chipset has no ram so it uses system mem)
15 mb - os crap(pagepool,etc..)
32 mb - graphics mem
10 mb - camera buffer

256-64-15-32-10=137 mb available to wm

So remove the 15MB pagepool of WM and you're dangerously close to 158 MB 
already.
