I recall having to enable "Legacy Only" mode on various IBM UEFI servers to get USB storage to work correctly at boot time in the past. Maybe try that. Also check out this document: http://communities.intel.com/servlet/JiveServlet/download/84573-3395/introducing_uefi-compliant_firmware_on_ibm_system_x.1.0.pdf -- Quote -- USB storage: USB storage is similar to a hard disk in that it has an MBR. However, because it is removable media, the specification allows for USB storage to include a \efi\boot\bootx64.efi file. If a USB key contains the file, it is EFI bootable. You can place a fullshell.efi file on a USB key and rename it to \efi\boot\bootx64.efi. Then, if you boot to the USB key, it EFI boots to the shell. If there is no \efi\boot\bootxX64.efi file on the USB key, the UEFI boot manager examines the MBR, and if it is designated as bootable, the server goes into BIOS mode and boots the USB key. (See “Starting the UEFI shell” for information about obtaining and running the shell environment.) ------- Try investigating or placing /efi/boot/ files on the USB drive. The UEFI shell is also fairly useful for diagnosing boot issues. -- Tim _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list
