Subject: Statement of Volatility – Dell Precision Workstation T7600

Gentlemen:

The Dell Precision Workstation T7600 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 T7600:

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 U35 on the 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.
