Description of Problem:
The RedHat 7.1 installer doesn't appear to recognize memory above 16MB
on some systems, and thus the installation fails.
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?
