My experience is RH9 auto detected machines >= 2GB of RAM and installs the PAE bigmem kernel by default. I'm pretty sure the FC2/3 installer will do the same.

I understand that the 2.6.* kernels are much better at large memory
support (with respect to performance issues), so unless you have a
64-bit machine lying around - this is probably worth a try.

You may need to build a new kernel with the various parameters :

CONFIG_NOHIGHMEM
CONFIG_HIGHMEM4G
CONFIG_HIGHMEM64G

set appropriately (or even upgrade to the latest 2.6.10). I would expect
that some research and experimentation will be required to get the best
out of it - (e.g. the 'bounce buffers' issue).


In the standard rpm FC 2-3 with a newly install server , would it automatically
detect and config it if I use the mechine with > 4 Gb [6Gb.] or should I
manually config it?
