Ensure BMC release 00.50 or later is pre-installed before attempting this FRU/SDR update. 2. Copy all of the files in the FBC_21.zip archive to a USB key, hard disk drive or floppy drive. All of the files in this zip archive must reside in the same directory. 3. Boot to EFI and then execute the following script to bring up the main FRU/SDR load menu: updFBC.nsh 4. Boot to EFI and then run the following command to display the contents of the baseboard FRU device: FRUSDR /d FRU If device is empty, which is the case for all new FAB4 baseboards, then execute the following command to program the empty FRU device: FRUSDR /fru BC_BMC.fru 5. Now execute the following command to bring up the main FRU/SDR load menu: FRUSDR /cfg master.cfg 6. Select the option which is applicable to what you want to do. On a brand new baseboard I would highly recommend to run option 3 to program both the FRU and SDR. By reprogramming the FRU you will be given the option to input data from the keyboard into various chassis, board and product areas. Ensure that you select the correct chassis from the chassis selection menu otherwise your fan sensors will not be configured properly. 7. If the following message is displayed: "This is either the incorrect FRU/SDR package for this baseboard or your platform ID is incorrectly programmed." Then you need to ensure that you are installing this package on a S5500BC baseboard and that your platform ID is correctly programmed. 8. The package should auto-detect the chassis. If it does not, it will print an error message indicating why auto-detection failed and then present the standard chassis selection menu. 9. Once the package has finished its installation, I would highly recommend to DC power off the system and cycle AC power. ============================================================================= KNOWN ISSUES/WORKAROUNDS ============================================================================= - Some Power-on chassis do not support a 2-wire SMBus front panel temperature device so this FRU/SDR package will not install the front panel temperature sensor data record. This will be resolved once Alpha chassis hardware becomes available which does have support for 2-wire SMBus front panel temperature device. - Processor VRD Hot sensors and CPU status sensors will log events and cause the front panel status LED to indicate a fault. This is a know issue with the BMC firmware rev 00.05 and will be resolved in the BMC 00.06 release. ============================================================================= FEATURES ADDED ============================================================================= FBC_21 (Gold 7): - Corrected some errors in three "other" sheets according to the BluffCreek_CONFIG-FSC_V2.1.xls. - Update other chassis names according to the BluffCreek_CONFIG-FSC_V2.2.xlsm.
