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.

To generate a golden (known reliable) CMOS image, use the BIOS Setup Utility to configure the BIOS settings.

To capture the 256 bytes of CMOS containing the configuration information, type:

# biosconfig -get_CMOS_dump filename.xml

The following display shows an example of the output.
