thanks for pointing out this, because I was curious and grepped the config
files on my 32bit system.

I'm not familiar with "M$", but if you're referring to "MS", short for
"Microsoft",

With pae enabled kernel on 32bit systems, you can split memory on 4GB
slices.
It comes with some overhead, but still works fine. also 4GB process
limit applies to processes.

MS allows some versions of Windows systems to bypass such limit on 32
bits machines (by means of PAE and AWE), so yes, nowadays it's fictional.

IIRC the answer is yes, it's a "natural" one, imposed by the address
lines being limited to 32 bits: 2^32 gives you 4G, the remaining 1G was
last seen being swallowed by the "Doors, Gates and

Hi,
Sorry if it is a FAQ,
Is the 3G memory access limit is the natural one, or something
superficial imposed by M$? I mean, does 32bits Linux (the i386
architecture) has such 3G limit as well?
thanks
