How is data input to this memory?

Planar, Poweredge T610

	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
System BIOS SPI Flash	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)
	Loading flash memory requires a vendor-provided firmware file and loader program that is executed by booting
LOM Configuration Data	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 would not operate.
iDRAC6 Controller ROM	N/A

How is this memory write protected?

How is the memory cleared?

N/A - BIOS only control

Planar NVRAM_CLR jumper or remove AC cord, remove cover, remove coin cell battery. Wait for 30 seconds, replace battery, cover, and then AC cord.

F2 system setup option to restore defaults

2.5" backplane or 3.5" Backplane

Storage Controller Processor

Embedded firmware only writeable through controlled iDRAC methods

Not possible with any utilities or applications and backplane does not function as expected if corrupted/ removed.

PSU Microcontroller

Protected by the embedded microcontroller. Special keys are used by special vendor-provided utilities to unlock the ROM with various CRC checks during load.
