How is this memory write
protected?
N/A - BIOS only control
Embedded firmware only
writeable through
controlled iDRAC methods
OS control
Protected by the

utilities to unlock the ROM
with various CRC checks
during load.
Unprotected

Protected. No iDRAC
embedded firmware
writes to this device.
Theoretically, IPMI I2C
Master write commands
would flow through to
overwrite this EEPROM.
SHA1 encryption
included. Storage
Controller use only.

How is the memory cleared?
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
Not possible with any utilities or applications and backplane does
not function as expected if corrupted/removed.
OS control format
