I have a basic install of xCAT installed via RPM on a CentOS 6.4 machine,
configured according to the QuickStart guide. However, I cannot discover my
compute nodes according via Sequential Discovery. DHCP properly responds to
the request and I see a tftp request in the logs. However, on the node
console, it give a "File not found" error message.

On my head node, all of the pxeboot files are in subdirectories:

How do I get this system to pxeboot correctly?
