Is linux limited to 4GB memory?
Nope, not 2.4 anyways. I don't remember the limit, but it's a big number. ;-)
I have inherited some boxes with 5GB each and I'm planning on loading linux.
Some things to remember - if these are x86 architecture boxes, you still have a 3GB per process user space limit. Even with 64GB of RAM, no single process can see more than 4GB and the top 1GB of that is mapped as kernel space. Big memory means that you get to have lots of large virtual address spaces that can remain mapped in physical RAM. For virtual address spaces with wider than 32-bit addresses, you need 64-bit processors. ccb -- Charles C.
