Pae

Does the standard Arch x86 (32bit) kernel support PAE? If so, how does one enable it? Searching for PAE on the wiki doesn't bring up anything.

Thanks!

Re: Pae

If I'm not mistaken, you have to enable HIGHMEM64G in the kernel config in order to use PAE. Default Arch kernel doesn't have that enabled - PAE-enabled kernel wouldn't work on non-PAE-enabled hardware.

Re: Pae

The enabling of highmen 64G requires re-compiling the kernel.

Search the web for PAE and its consequences before you decide to re-compile.

How to recompile kernel with all options set by Arch Team plus this PAE?
I have 4GB memory and I need to see it but 3.5GB like right now.

One way would be to just  grab all required kernel26 files from abs and edit the PKGBUILD to incorporate a 'menuconfig' (or similar) just before the  "# build!" line to be able to select PAE. A simpler way would be to directly select PAE support in the Kernel26 .config and use abs from there.
cheers,
