Appendix A. Statement of Volatility

The Dell PowerEdge R515 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. Components chosen as user- definable configuration options (those not soldered to the motherboard) are not included in the Statement of Volatility. Configuration option information (pertinent to options such as microprocessors, system memory, remote access controllers, and storage controllers) is available by component separately. The NV components detailed in Table 25 are present in the PowerEdge R515 server.

Size:

 

 

32Mbit

 

 

 

 

 

 

Type [e.g., Flash PROM, EEPROM]:

 

 

Flash EEPROM

 

 

 

 

 

 

Can user programs or operating system write

 

 

No

 

data to it during normal operation?

 

 

 

 

 

 

 

 

 

Purpose? [e.g., boot code]

 

 

Boot Code and Configuration Information

 

 

 

 

 

 

How is data input to this memory?

 

 

Loading flash memory requires a vendor

 

 

 

 

 

provided firmware file and loader program

 

 

 

 

 

which is executed by booting up the system

 

 

 

 

 

from a floppy or OS based executable containing

 

 

 

 

 

the firmware file and the loader. System loaded

 

 

 

 

 

with arbitrary data in firmware memory would

 

 

 

 

 

not operate.

 

 

 

 

 

 

How is this memory write protected?

 

 

Software write protected
