		How is data input to this memory?
Planar
System BIOS SPI Flash		Loading flash memory requires a vendor-provided firmware file and
		loader program which is executed by booting the system from a
		floppy or OS-based executable containing the firmware file and the
		loader. System loaded with arbitrary data in firmware memory will
		not operate
LOM Configuration		Loading flash memory requires a vendor-provided firmware file and
Data		loader program which is executed by booting up the system from a
		floppy or OS based executable containing the firmware file and the
		loader. LOMs loaded with arbitrary data in firmware memory will not
		operate.
iDRAC6 Controller		iDRAC embedded system
RAM
System CPLD		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 (currently only DRMK utility support)
		containing the firmware file and the loader. System loaded with
		arbitrary data in CPLD memory will not operate.
iDRAC6 Express		Not used
Internal Flash
		iDRAC OS: Loading flash memory requires a vendor-provided firmware
		file and loader program which is executed by booting the system from
		a floppy or OS-based executable containing the firmware file and the
		loader. System loaded without a good iDRAC firmware image yields a
System RAM		non-functional iDRAC.
