Hi,

For my internship, I have to find a way to manage more than 4GB of
memory with 32 bits processors. It seems that the FreeBSD kernel is the
perfect candidate for that. According to the architecture handbook(*),
"FreeBSD could theoretically handle memory configurations up to 8TB on a
32 bit platform."

For the last two days, I was looking for documentation, articles,
thesis, or e-mails on that topic, but I can't find relevant
informations. Is anybody have informations on that topic ? Where should
I start to read the source code to find my answers ?

Thank you in advance.
