FC4 - Does Fedora recognizes memory?

[Hoffmann]

Hello:

In the future, I intend to add more memory to my
machine. Does Fedora (automatically) recognizes the
new memory, as Windows does?

Thanks,
Hoffmann

No recognition needed.  The motherboard is the only device that needs to
recognize the memory.  Fedora will use all available memory regardless
of how little or much.  (At least to 4G)

For the most part, yes.

On x86-64, it'll just work.
On 32 bit x86, if you have > 4GB, you'll need to run kernel-smp
instead of 'kernel' (even if you only have 1 CPU).

Yes. You may need a different kernel if you put in more
the the kernel was compiled to support. (1MB, 4MB, 4MB+
for X86 machines)

As I know 4G memory is default for kenerl. If the memory is larger
that 4G it need to recompile.

Not true. The SMP kernel supports (theoretically) up to 64GB.
In practice after 8->16GB, you really want to be thinking of
moving to a 64bit system.  A few years ago, making stupid amounts
of memory work on 32 bit made sense, now.. not so much.
