4.1.2 Flash update As part of your installation procedure for the x450, we recommend that you check the firmware levels on the system components and update to the most current revision: System firmware Onboard diagnostics Remote Supervisor Adapter firmware Additional devices if installed, such as ServeRAID adapters and FAStT Fibre Channel host adapters The latest updates and firmware code can be found at: http://www.pc.ibm.com/qtechinfo/MIGR-4JTS2T.html System firmware and diagnostics updates Unlike an IA-32 platform, the normal boot process does not permit booting from a diskette, so a flash update procedure must start differently. The flash program is embedded in the system. To start a flash update, select Flash Update from the Boot Manager menu (Figure 4-1 on page 69). Once the program loads, it looks exactly like the diskette version but with one change in the EFI version. The diskette version searches for the update files on the diskette, whereas the flash program on x450 reads the root directories of all accessible file systems until it finds firmware update files. The implication is that once the utility successfully locates a flash update file, it will stop searching. Tip: The routine that searches all devices for suitable flash files stops as soon as it finds the first one in the root directory of a file system. This may not be the newest flash file. The routine does not search subdirectories. We should realize this behavior when we have, for example, the latest firmware updates on a USB memory key and an older version stored in the root of EFI System Partition. In such situations, the flash update utility will keep offering only the older file for update. To resolve the issue in this specific case, we have to delete the firmware update files from the system partition and repeat the procedure. If you want to delete the files from ESP, enter the EFI shell, identify the EFI System Partition and use the rm command (for the exact syntax, use the help command). 80 IBM ^ xSeries 450 Planning and Installation Guide
