Description of Problem: The RedHat 7.1 installer doesn't appear to recognize memory above 16MB on some systems, and thus the installation fails. How Reproducible:
There is a bug in the way some motherboards report their amount of memory to the kernel. You can force it to recognize all your RAM by passing 'linux mem=xxxMB' where 'xxx' is the amount of RAM that you have. Does this fix the problem?
