Made some progress today. In my research on creating custom pxe boot file for Linux images I found another post talking about customizing ipxe boot files. Interestingly he mentioned adding two lines in the dnsmasq.conf file. In Centos 6.5 this file is in the /etc folder. When I examined the file the two lines where there, but remarked out.
# Include a another lot of configuration options.
conf-file=/etc/dnsmasq.d/ltsp.conf
conf-dir=/etc/dnsmasq.d
After I un-remarked and added the lines above restarted the service and my test system promptly displayed my ipx option option screen 30 second countdown: A network boot, B hard drive boot.
I selected network boot and I was shocked to see the standard fog screen come up. This may have fixed it?
Unfortunately when I tried to register the computer the process jammed with an error
/bzImage32… 21%
I am very close now though and with some more work I think this will work in Centos 6.5 not using fog as a dhcp server but as a proxy dhcp server with the fog pxe boot options.
I am happy. Hope this helps someone else this was painful to figure out. I now understand the .0 automatically being added. I still don’t understand the difference between the undionly.pxe file and the unkionly.kpxe file, but I am taking this as a win!!!
Thanks for your help guys.
