HTTP Boot Setup

This is the kernel that will boot.
This file can be copied from any machine that has RHEL5.3 installed.
2. Start httpd

Steps on the gPXE Client

1. Ensure that the HCA is listed as the first bootable device in the BIOS.
2. Reboot the test node(s) and enter the BIOS boot setup.
This is highly dependent on the BIOS for the system but you should see a
menu for boot options and a submenu for boot devices.
Select gPXE IB as the first boot device.
When you power on the system or press the reset button, the system will
execute the boot code on the HCA that will query the DHCP server for the IP
address and boot image to download.
Once the boot image is downloaded, the BIOS/HCA is finished and the boot
image is ready.
3. Verify system boots off of the kernel image on the boot server. The best way
to do this is to boot into a different kernel from the one installed on the hard
drive on the client, or to un-plug the hard drive on the client and verify that on
boot up, a kernel and file system exist.
HTTP Boot Setup
gPXE supports booting diskless machines. To enable using an IB driver, the
(remote) kernel or initrd image must include and be configured to load that driver.
This can be achieved either by compiling the HCA driver into the kernel, or by
adding the device driver module into the initrd image and loading it.
1. Make a new directory
2. Change directories
3. Create a initrd.img file using the information and example in

4. Create a uniboot.php file using the example in
