RE: Bigmem Kernels in RHEL AS 5

Ok, once more - figured this out - to support more than 4GB
RAM on RHEL AS 5 32-bit machines, you must install the PAE
kernel.

I've happily got 16 CPU's and 8GB RAM now.  Well, I'd be
happier using 64-bit, so it's as happy as I can get at this
moment 

Cheers,
Mike.

Ok, I think I figured this out - for application reasons,
the 32-bit version of RHEL AS 5 was installed.  By default,
32-bit Linux doesn't support more than 4GB RAM.  I've heard
you can enable more than 4GB of RAM on 32-bit systems.  Can
someone point me to a HOWTO for doing that, or give me a
quick explanation?

Thanks,
Mike.

Hmm... I have 8GB of RAM in the machine, and POST shows 8GB
on boot, but the OS sees only 4GB.

I believe that since RHEL4 the default installed 2.6.9
kernel will  
handle large amounts of memory just fine. Red Hat puts
artificial  
limits on their kernel but even in WS it is like 16GB.
