Is PAE enalbed for CSM on 5,1s?

[Project Alice]

I am thinking about installing Server 2003 in an extra drive on my 5,1 as I miss the XP days sometimes, and theres a few old games I'd like to play again that don't get along with anything above the NT5.x versions of windows.
Anyways, Win2003 32bit can take 64GB of ram as long as it has PAE. I can't find anything on google about it. If it won't have PAE I can use the 64bit version, it just that drivers are easier to come by for the 32bit variant.

Also just to address this now because I know its coming: I don't care that the OS isn't supported, I won't be doing online banking using it. If it gets malware I can reinstall the OS in about 15 minutes. If you're going to tell me not to use a 15 year old OS, don't even reply please. Yes I know about VMs, I use them all the of the time. I want a bare metal installation. Thanks!

I’d say PAE should be platform independent. Server 2003 should also have PAE enabled by default. Not 100% sure. 64bit in XP era has more problems than the benefit it brings in terms of application support based on my experience.

PAE I thought was usually a BIOS option as long as it was supported with the CPU, like virtualization support. I might be wrong about that though. I will probably just install it and find out for myself if it's enabled or not.

You're definitely right about 64bit application support. I've forced a lot of things to install on 64bit XP/2003, and they work once installed. But anything that relies on a certain driver or a service that was only 32bit won't work (such as those old starforce copy protection drivers games used). This is why it would just be easier to use 32bit.
