How is data input to this memory?

Planar

System BIOS SPI Flash

Loading flash memory requires a vendor-provided firmware file and loader program
that 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. Future firmware releases may add support for
recovery of a bad/corrupted BIOS ROM image via the iDRAC (administrator privilege
plus specific firmware, binary, and commands).

LOM Configuration Data

iDRAC6 Controller ROM

N/A

iDRAC6 Controller RAM

iDRAC embedded system.

System CPLD (EPROM)

Loading flash memory requires a vendor-provided firmware file and loader program
that 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 would not operate.

iDRAC6 Express Internal
Flash

iDRAC OS: Loading flash memory requires a vendor-provided firmware file and loader
program that is executed by booting up 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 non-functional iDRAC. Managed Services Repository:
Various partitions are loaded via vendor-provided firmware file and loader program
just like iDRAC OS.
