Hello,
I am trying understand the swap. I would like to know which is the
maximum swap size on i386. Is 64 MB? If yes, how to know the origin of
this "magic" number? I don't found it (Internet).
Thanks in advance.

Look into the manpage of mkswap. It's 2 G x 32 swap partitions,
minus a tiny overhead.

Ok. But, mkswap man is old (1999). However, from Linux Partition HOWTO:
"footnote: "official" max swap size: With kernel 2.4, the limit is 64
swap spaces at a maximum of 64Gb each, although this is not reflected in
the man page for mkswap. With the 64 bit opteron on the 2.6 kernel, 128
swap areas are permitted, each a whopping 16 Tb! (thanks to Peter Chubb
for the calculation)"
I want to know: why 64 GB???
Thanks,

It's how big the available pointers are.
