I have a box that we recently installed 16GB of RAM on. The box is i386
FreeBSD 6.2. It only recognizes 4gb.
I am currently recompiling the kernel to support options PAE (KERNCONF=PAE)
in order to see this. I understand this is still considered a Beta
implementation ,and this is a production box.
Does anyone have any alternative solutions that would provide a more
reliable environment other than PAE?
