I have to check which version is here (used by my son :) )

Ahh, the slim version is a new toy. As our one was purchased in May for sure it is LINUX compatrible. Will try YellewDog, it was already planned...

Wouldn't you need 64-bit applications in addition to a 64-bit kernel to take advantage of >4gb ram?

I've compiled a multi-lib build - 64-bit kernel and 32/64-bit apps - on a ps3, the difficult part was to prevent the compiler from makeing 64-bit apps, so I have a feeling that if you compile the tinycore source on a 64-bit machine, it would automatically compile a 64-bit kernel.

You can look at http://cross-lfs.org/view/svn/x86_64-64/ for pointers

Definately 4gb, and definately only showing up as 3gb.

Hmm... but really..? That simple? just compile the source on a 64bit machine? I assume the build environment would have to be 64bit at least. Will take a look at the CLFS stuff later. I'll be surprised and impressed if it's that simple.

Juanito:
I use ydl from time to time, but it's way too bloated for a ps3 - hence compiling the cblfs multi-lib...

2^32 = 4.29GB or 34.36Gb

There might be some confusion on how the memory capacity is measured or how the system shows the memory. But a 32 bit machine can reference 4G of memory for sure.
