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. -----Original Message----- From: Young, Mike Sent: Friday, March 23, 2007 11:20 AM To: 'General Red Hat Linux discussion list' Subject: RE: Bigmem Kernels in RHEL AS 5 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. -----Original Message----- From: Young, Mike Sent: Friday, March 23, 2007 7:44 AM To: 'General Red Hat Linux discussion list' Subject: RE: Bigmem Kernels in RHEL AS 5 Hmm... I have 8GB of RAM in the machine, and POST shows 8GB on boot, but the OS sees only 4GB. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of David Miller Sent: Friday, March 23, 2007 12:37 AM To: General Red Hat Linux discussion list Subject: Re: Bigmem Kernels in RHEL AS 5 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. David.
