Sorry, I don't know about HP's iBFT support. IBM blades support iBFT out-of-the-box. I took a look at that PDF, and it seems much of that is for distros without iBFT support. Also, it's dated May 2008. RHEL5.2 was released in May 2008, and it's the first release of RHEL to have (preliminary) iBFT support. I think you'd need newer documentation from HP.. -- Pasi _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
