## Symptoms

- * In an environment with several appliances that have identical hardware (such as a Maestro Security Group with identical Security Group Members), one appliance reports a different total memory capacity.

* The output of the `g_all free` command shows the discrepancy in Total Memory.

  Example for a Maestro Security Group:

  ```
  
  EXPERT ## g_all free
  1_01:
                 total          used          free       shared     buff/cache  available
  Mem:        32,663,536      5247336        24642272    17636       2773928     26491128
  Swap:        32964476           0          32964476   
  
  2_01:
                 total          used          free       shared     buff/cache  available
  Mem:        32,662,904      5176836        25389332     7304        2096736    26602380
  Swap:        32964476          0           32964476
  ```

## Cause

The affected appliance is running with the Recovery BIOS instead of the Primary BIOS.

You can verify this by running the following command:

`EXPERT## dmidecode -t 11`

Sample Output:
`# dmidecode 3.0`  
`Getting SMBIOS data from sysfs.`  
`SMBIOS 3.0 present.`  

`Handle 0x0022, DMI type 11, 5 bytes`  
`OEM Strings`  
` String 1: Recovery BIOS`
