Statement of Volatility - Dell Precision Workstation R7610 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Precision Workstation R7610 contains both volatile and non-volatile (NV) components. Volatile components lose their data immediately upon removal of power from the component. Non-volatile components continue to retain their data even after the power has been removed from the component. The following NV components are present on the R7610 system board. BIOS Configuration The BIOS information is stored in two flash ICs, one 8 MByte and one 4 MByte. These devices are identified as U_BIOS1 and U_BIOS2 on the motherboard. These parts contain the boot code and data necessary to take the hardware from a power- off or low- power state to a state where it is ready to be managed by the operating system. No information pertaining to user applications or data is stored in these devices, however, they do store administrator and/or hard drive encryption passwords if those features are enabled by the user. Embedded Controller The Embedded Controller contains 256 kByte of non- volatile storage space and is identified as U_EC1 on the motherboard. The EC contains the software necessary to manage low- level control functions on the motherboard such as thermal control. No information pertaining to user applications or data is stored in the U_EC1 device. The embedded controller also contains 8.25 kBytes of volatile memory space. The contents of this memory space are lost when power is removed from the system. PCH CMOS The PCH, identified as U_PCH, contains a 256 Byte battery- backed memory. This memory contains custom configuration data required by the BIOS to boot the system. It does not store passwords or other user level data. The contents of this space are lost, after several minutes, if the coin- cell battery is removed from the motherboard. Ethernet Controller EEPROMs The Ethernet Controller EEPROM is identified as U4 on the Rear IO motherboard. It is a 2 kbit device. The Ethernet Controller EEPROM stores driver information and the system MAC addresses. It does not store password, IP address, domain name, system ID, or similar information. TPM 1 .2 (Trusted Platform Module) Security Device This device (identified as U_TPM) stores TPM configuration data used by the hardware and the security software offered by Dell. Encrypted user keys generated by the TPM device for use by the security software are stored in this NVM. All other components on the motherboard will lose data once power is removed from the system. Primary power loss (unplug the power cord) will destroy all user data in the main system memory (DDR3 DIMMs) and the on- board graphics and storage interface devices. May 2013
