Re: PAE Kernel?
zgrep HIGHMEM64 /proc/config.gz
# CONFIG_HIGHMEM64G is not set
Bad luck.

Re: PAE Kernel?
Is the default kernel package for Arch compiled with PAE enabled?
In case you didn't understand the last guy, he was showing you how to search your current kernel. Anyway, it's not hard to fix this issue with the makepkg/abs system, just `sed` the config.* file to set HIGHMEM accordingly. If you need highmem support and use ccache for compiling you can get kernel compilation down to few minutes.

Re: PAE Kernel?
But keep in mind that it will be kinda slow when you need the RAM that you gain because of HIGHMEM.

Noticeable 'slowness?' I mean, he apparently has a good setup if he needs over 4 gig of mem support. The extra time it takes to access that memory will easily be outweighed by the benefit of having more memory.

How much slower? I'm considering moving from 64 to x86 because of problems with WINE.

Re: PAE Kernel?
Not too much slower... somewhere around 5% I'd guesstimate. But IMO there's no point using PAE if you can do x86_64. Wine should work perfectly fine?

According to the wine devs, there are bugs with combining the 64bit and 32bit nvidia drivers. I get slowdowns and crashes that I never got before.

Re: PAE Kernel?
Huh? Combining the 32-bit and 64-bit NVIDIA drivers? Whyever would you install both? The 64-bit NVIDIA drivers work fine for 32-bit Wine, I've been using them for quite a while.

Re: PAE Kernel?
You need nvidia (64-bit kernel module) and lib32-nvidia-utils (libgl 32bit stuff for wine), and most likely nvidia-utils (64-bit libgl stuff for Xorg, unless you want to run a 32bit Xorg) too.

Re: PAE Kernel?
It's fine to enable PAE and continue the use of 32bit. It makes life a lot easier.
I personally don't plan to switch to 64bit anytime soon.
