Is common to want to convert the ESX cd into an ISO file – and mount into ILO session to install to blade servers – rather than having to take off a dongle and attach an external IDE-CD-ROM. Problems can occur with certain plade systems. The problem isn’t immediately obivious – you will get 2/3rds of the way through the ESX install and then freeze. Solution? BIOS update on the ILO cards general fixes this issue.
