Installation Instructions * * * * Please print out these instructions or write them down before * * starting this flash update utility. * * * * BIOS update by UEFI utility: There is now one compressed folder * * released with each BIOS (image name **JTxxUSA.ZIP), containing the * * BIOS image, Shell flash utility, script files for auto execution, * * release note and flash instructions. Unpack and copy all files in * * **JTxxUSA.ZIP to the root of USB memory key. * * * * BIOS update by bootable CD: There is now one CD image file * * released with each BIOS (image name **J9xxUSA.ISO), containing the * * BIOS image, UEFI flash utility, release note and flash instructions. * * If you prefer to create a bootable CD to update BIOS, please follow * * the instructions for CDROM. * * * ***************************************************************************** ***************************************************************************** * About Applied Fixes or Features Added * * * * CHANGES.TXT is a file that lists known problems which are corrected * * and/or features added after applying this update to your system. * * If you like, please take the time to read or print that file before * * using this flash program to update your system BIOS. * * * ***************************************************************************** ***************************************************************************** * Basic Installation Instructions * * * * 1. Please make note of any settings you have changed in the BIOS * * Setup utility. They may have to be re-entered after updating * * the BIOS. * * 2. Please disable Secure Boot options in Security menu and check * * CSM options is disabled in Startup menu before flash BIOS. * * 3. Use the flash update program by putting it in a USB storage * * key, or creating a CD with the ISO image. Power up the * * system and make sure the device with the flash program is * * selected as a boot device. * * 4. The current BIOS level on the computer is compared to that of * * the flash update. If the levels are the same, or the level on * * the update is older than the ROM, a message is displayed stating * * "BIOS ROM file is older than (or same as) BIOS ROM image. * * Continue anyway? (y/n)", type in 'y'. * * 5. Update may take up to 2 minutes. Do not power off or restart the * * system during this procedure! * * 6. After the flash update is complete, system will automatically * * reboot. Don't forget to remove the flash device or you may be * * got your BIOS re-updated. * * 7. Please enable Secure Boot options again after BIOS upgrade, this * * could protect the security of Windows 10 * * * ***************************************************************************** ***************************************************************************** * 2. Flash Program Options * * * * The default operation of the flash update program is a step by step * * dialogue with the user that presents choices and gathers responses * * from the user about which choices are desired. * * * * In some situations (such as a large enterprise with many systems * * that need updating), it may be desirable to create a flash update * * image that requires no manual intervention to perform an update * * operation. This can be done by modifying the script file * * (startup.nsh) calling the flash program with the following * * command: * * * * flash2.efi [option1] [option2] ... [optionX] * * * * [OPTIONS] * * /h Show help messages. * * /rsmb Preserve all SMBIOS structures. * * /clr Clear BIOS settings. * * /ign Ignore BIOS version check. * * /sn:nnnnnnn Update system serial number (up to 20 characters). * * /csn:nnnnnnn Update chassis serial number (up to 20 characters). * * /mtm:nnnnnnn Update machine type and model number (up to 25 * * characters). * * /tag:nnnnnnn Update system asset tag (up to 25 characters). * * /uuid The flash utility will generate an Universally * * Unique Identifier (UUID), replacing the one that * * is currently in the system. * * /reboot Reboot after all requests done. * * /pass:nnnnnnn Input current system password. * * /quiet Operating without physical presence. * * * * The following example shows how to update system asset tag number * * to "1234567" use command line: * * flash2.efi /tag:1234567 * * * * The following example shows how to update bios and update system * * asset tag number by one command: * * flash2.efi bios.rom /tag:1234567 * * * * Note: A flash update image using these program options should be * * tested carefully before widespread usage. * * * ***************************************************************************** ***************************************************************************** * 3. Instructions for CDROM * * * * Create a CD with the BIOS package **J9xxUSA.ISO. Power up the * * system and immediately insert the flash CD in the CDROM drive. * * Ensure that you boot from the CDROM. * * * * You can modify the serial number and machine type/model if needed. * * Follow the instructions for using the flash update program in the * * basic installation instructions. The utilities mentioned above are * * located in a subdirectory on the CD. * * * ***************************************************************************** ***************************************************************************** * 4. Flashing Back to an Older Level of BIOS * * * * In order to flash back to an older level of BIOS, the following * * steps should be used to insure the latest flash utility is used. * * * * 1. Obtain the older level and latest level BIOS update programs * * from the Lenovo website. * * 2. Copy imagexx.rom from the older BIOS update program folder, * * paste it and replace the same file in the latest level BIOS * * update program folder. * * 3. Boot with the latest level update program and follow normal * * procedures. * * * ***************************************************************************** ***************************************************************************** * 5. AMIDEEFIx64 - AMIBIOS DMI Editor for Shell * * * * AMIDEEFIx64.efi [option1] [option2] ... [optionX] * * * * Options: * * /SP "String" Update the System Machine Type and Model Number. * * /SS "String" Update the System Serial Number. * * /CS "String" Update the Chassis Serial Number. * * /SU auto Update the System UUID. * * /SV "String" update the System Brand ID. * * /CA "String" update the Chassis Asset Tag Number. * * * * * ***************************************************************************** ***************************************************************************** * 6. Flash Customized Logo * * * * logo.nsh <logo file name> * * * * The size of logo file after compression should be less than 8KB * * (the size of compressed logo file is displayed on the screen during * * the processing). * * * * The following example shows how to change the power-on logo. * * logo.nsh myfav.bmp * * * *****************************************************************************
