How to Capture the BIOS CMOS Golden Image

The BIOS configuration consists of the contents of the CMOS and the boot tables in the NVRAM. The command biosconfig –get_CMOS_dump captures the 256 bytes of CMOS, but it does not gather the boot table information from NVRAM.

So this command might not capture the boot-order information, unless the bootable I/O configurations for the source and destination machines are the same.

1. To generate a golden (known reliable) CMOS image, use the BIOS Setup Utility to configure the BIOS settings.
2. To capture the 256 bytes of CMOS containing the configuration information, use the following command:

   biosconfig -get_CMOS_dump filename.xml

   The following is example output for the command.
