XP memory/disk support

[Timboi]

You would think it's easy to find the answer to this question in a nice table
somewhere but I haven't been able to find it.
I'd like to know how much memory and disk space the various flavours of XP
can support.

Cheers,

Disk space is unlimited, unless you are referring to the native partitioning
size limits when creating a FAT32 volume . On memory,:

All 32-bit versions support 4GB of RAM (but can only use around 3.1GB
of it).

All versions support NTFS volumes of 16 terabytes.

Except Starter, of course. I think it only supports 1GB.

Thanks for the addition--I forgot about that. I'm not sure what it
supports.

That page discusses PAE (Programmed Address Extension). It says that
PAE allows 32-bit Intel machines to address as much as 64GB of RAM,
which is correct. But 32-bit WinXP doesn't support that. It uses PAE
only to enable DEP (Data Execution Prevention). The result is that
32-bit WinXP supports at most 4GB of RAM. (And, as Ken said, you can't
actually use that much. See http://members.cox.net/slatteryt/RAM.html
for a discussion.)
