Hello. Do you have QLogic HBA card installed on this server? If so, it may not be configured to boot from external storage because it is disabled. Enable the adapter using Ctrl+Q during POST and monitor the messages thereafter.
I just recently bought a T710 and a strange message shows when booting:  ROM Bios not installed BIOS for adapter 1 is disabled BIOS for adapter 2 is disabled  Should I worry or just leave it as is?
ROM Bios no tinstalled
