* 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 *
|
|
