The system machine type and model (MTM), serial number, or system brand ID in the BIOS menu can be corrected through a command line program in the system BIOS flash utility. Refer to the instructions below:
1.From the Lenovo support site (
http://support.lenovo.com), search for the applicable system BIOS Package for the system, and download either the USB Drive/DOS flash program (.zip file) or the CD ISO flash program.
2.If using the USB Drive program, create the DOS bootable memory key and copy the BIOS flash files to the key. If using the CD ISO flash program, create the bootable CD.
3.Power on the system and make sure the device with the flash program is selected as a boot device.
4.Use the below DOS command to flash the machine type and model, serial number, or system brand ID in BIOS:
To flash machine type and model: amidedos.exe /sp “String”
To flash serial number: amidedos.exe /ss “String”
To flash system brand ID: amidedos.exe /sv “String”
“String” is the target MTM/ SN/ system brand ID.
The following command line shows how to update the machine type and model number to "1234567":
Amidedos.exe /sp “1234567”
