Subject: Statement of Volatility – Dell Precision Workstation T5610
Gentlemen:
The Dell Precision Workstation T5610 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 memory components are present in the T5610:
BIOS Configuration
The BIOS information is stored in two flash ICs, one 8 MByte and one 4 MByte. These devices are identified as U_BIOS1and U_BIOS2 on the motherboard. These parts contain the boot code and data necessary to take the hardware from a poweroff 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 256kByte of non-volatile storage space and is identified as U_EC 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_EC device.
The embedded controller also contains 8.25kByte 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.
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.
