Choose "1 - Update POST/BIOS". 3.4 You will be asked if you would like to move the current POST/BIOS image to the backup ROM location. If you select 'Y', the current code will be flashed in to the backup bank immediately. 3.5 If the current system POST/BIOS supports the Asset Tag feature, you will be asked if you would like to change it. If you select 'Y', you will be able to enter a new number. 3.6 You will then be asked if you would like to save the current code to a disk. If you select 'Y', you need to have a formatted disk already available, or specify a fully qualified path and file name. 3.7 At this point, the image will be loaded from the disk, and you will be asked to choose which language you wish to use during POST and in Setup. If you select a choice other than English, the selected language will be merged into the image. There is also an option to Quit the flash update on this menu. 3.8 After this completes the system will update the flash ROM with the new code. When this is complete you will be prompted to remove the disk and hit return to reboot the system. 4.0 Configuration Information 5.0 Unattended Mode 5.1 Steps for unattended mode. 5.1.1 Modify CONFIG.SYS on the Flash Diskette to read: "SHELL=FLASH2.EXE /u /r" Or use FLASH2.EXE /u /r from your script. /u is for unattended mode /r is to specify reboot after flash is done ** reboot is recommended after flash. 5.1.2 Reboot the system with the Flash Diskette in Drive A: ** Note: An optional parameter of "/a:" can be added to allow for storing a system asset tag number where "" is replaced with up to a 32 digit string. 6.0 Web Sites and Support Phone Number 6.1 IBM Support Web Site: http://www.pc.ibm.com/support 6.2 IBM Marketing Web Site: http://www.pc.ibm.com/ww/eserver/xseries/ 6.3 If you have any questions about this update, or problems applying the update go to the following Help Center World Telephone Numbers URL: http://www.pc.ibm.com/qtechinfo/YAST-3P2QLY.html. 7.0 Trademarks and Notices 7.1 IBM and the e(logo) are registered trademarks of International Business Machines Corporation. 7.2 U.S. Government Users Restricted Rights - Use, duplication or disclosure restricted by GSA ADP Schedule Contract with IBM Corporation.
