Will Arch See Large RAM?

I have a box with 6 GB of DDR2 RAM and normally under Debian I can either install x86_64 and go through Youtube withdrawal or I can simply install the i686 version and then load the 2.6.2x-i686-bigmem kernel and this allows Linux to see over 3.2GB's of RAM. Is this the case in Arch Linux using a 32 bit version?

I don't know about the particular question, but I run 64-bit Arch AND install Flash according to the info in the Arch Wiki.  I have 64-bit AND get YouTube.  Does that help?

Yeah - it tells me that Adobes proprietary version of Flash works on 64 bit kernels. Do you know if you used the older Flash 9 or the latest Flash 10 on your system?

Not by default, you would need to compile the 32bit kernel with pae enabled. However if flash is the issues theres other options, I just use the lib32 method with arch64 which works great. Check out the arch64 faq.

I have 8GB of RAM on my Arch64 system and it works fine (free displays all of it). The lib32 flash fix works too; I've had somewhat less succcess with gnash.

In case you wanted to get your hands dirty with a custom kernel compilation, the kernel you're looking for is
Processor Type & Features ---> High Memory Support ---> 64 GB.

If memory is the only issue, and you're willing to spend a bit of time poking around and learning about the kernel, I would suggest this method, as I haven't see too much speed increase between 32 and 64 bit Arch, and I've had a whole host of problems dealing with 64-bit distros (not just Arch)

I'm using: 2.6.25-ARCH x86_64

And playing a video with youtube with Opera (the world most advanced web browser). You don't have to do anything special, just copy the flash plugin to the right directory. Or you could just use Gnash.

I'm also using Arch64 with the lib32 flash method. It works well for the most part, but sometimes CPU usage of the plugin in really high. I don't notice it on my workstation but the laptop sometimes lags when running flash. YMMV.

Re: Will Arch See Large RAM?

Thanks all. Running Arch64 and all my RAM is available however when I did:

pacman -Syy
pacman -S firefox

Firefox installed fine however I have no flash plugin support and when it detects a missing plugin from a page, it will not auto install.
