DeWalt R510 manual Methodology for Memory and Clearing, Ram

Dell

SAS 6/iR Integrated

Controller	Loading flash memory requires a vendor-provided firmware file and loader program which is
Configuration	executed by booting the system from a floppy or OS-based executable (DUPs, Unified Server
Data	Configurator) containing the firmware file and the loader. Storage adapters loaded with bad
	firmware will not provide storage controller behavior.
FRU	Factory only. Not customer updatable.
Integrated
Mirroring NVSRAM	Embedded storage firmware controls this data
iDRAC6 Enterprise
vFlash	Preloaded media before installation, or remote out-of-band upload of user data (i.e., ISO images,
	files) or local server read/write capability to use like a hard disk.

Table 36. Methodology for Memory and Clearing

	How is this memory write
	protected?	How is the memory cleared?
Planar
System BIOS SPI Flash		Not possible with any utilities or applications and system is not
	Software write protected	functional if corrupted/removed.
LOM Configuration	Not explicitly protected
Data	but special applications
	are needed to
	communicate through the
	LOMs to reprogram this
	ROM.	Not user-clearable
iDRAC6 Controller	protected permanently by
ROM	hardware	Not clearable
iDRAC6 controller
RAM	n/a	iDRAC reset
System CPLD	Requires special system	Not possible with any utilities or applications and system is not
	specific utility	functional if corrupted/removed.
System CPLD	Not accessible	Not clearable
iDRAC6 Express	Writes are proxied through
Internal Flash	a temporary iDRAC
	scratchpad RAM and not
	directly made from an OS
	or OS application.	Not user-clearable
System RAM	OS control	Reboot or power down system
TPM ID EEPROM (Plug
in module only)	HW read only	Not - read only
TPM Binding EEPROM	Locked by BIOS from
(on China planar	physical access by anyone
only)	after boot	N/A - BIOS control only
