(Redirecting to the iPXE mailing list; see http://ipxe.org/faq)

I think the standard build as shipped by QLogic has the Ctrl-B prompt 
disabled.  You can try booting from the iPXE CD-ROM, which you can download 


You can attach this as a virtual CD-ROM via iLO.  This will allow you to enter 
the iPXE command line, where you can start testing.  The iPXE error page for 
the "Connection timed out" problem that you are seeing is at


and contains some hints and tips on dealing with this specific problem.

You should be able to use iPXE in the same way as a standard (Intel) PXE 
stack; there is no specific DHCP configuration required, and your usual OS 
deployment mechanisms (e.g. Altiris RDP) should work.
