adapter. The gPXE InfiniBand device should be listed as the first boot
device.

Boot Server Setup
NOTE:
The dhcpd and apache configuration files referenced in this example
are included as examples, and are not part of the QLogic OFED+
installed software. Your site boot servers may be different, see their
documentation for equivalent information.
Instructions on installing and configuring a dhcp server or a boot server
are beyond the scope of this document.
Configure the boot server for your site.
NOTE:
gPXE supports several file transfer methods such as TFTP, HTTP, iSCSI.
This example uses HTTP since it generally scales better and is the preferred
choice.
NOTE:
This step involves setting up a http server and needs to be done by a user

1. Install Apache.
2. Create an images.conf file and a kernels.conf file and place them in
the /etc/httpd/conf.d directory. This sets up aliases for and tells
apache where to find them:
/images — http://10.252.252.1/images/
/kernels — http://10.252.252.1/kernels/
