Statement of Volatility
HP confirms that Intel-based business desktop HP Sprout systems contain DDR3 volatile memory (memory
amount depends on the customer configuration). In addition, the motherboard in the condition originally
shipped without subsequent modification or the addition or installation of any applications, features, or
functionality, contains the following nonvolatile memory: Real Time Clock battery backed-up configuration
memory (256 Bytes), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128
Bytes programmable), Serial Peripheral Interface (SPI) ROM for System BIOS (16M Bytes) and Super I/O’s:
masked keyboard ROM (overall 2K Bytes).
The following procedure shows the steps that should be taken to restore the Non-Volatile memory found in
the Intel-based HP Sprout systems.
