But then, it's not completely accurate either ;-) I don't see it mention the largesmp and PAE kernels, for instance. Tim, I think the SL5/32 limit is 4 GB (3 GB usable) with the regular kernel, 16 GB with the PAE one. I guess the PAE kernel doesn't get as much testing in the field as x86_64. Just curious: why would you want to run a 32-bit OS on a machine with that much RAM? Regards, Stephan -- Stephan Wiesand DESY -DV- Platanenenallee 6 15738 Zeuthen, Germany
