SPI Flash
SPI flash is only
indirectly
connected to
iDRAC. iDRAC
can read any
address in the
SPI flash, but
may only write
the primary
firmware storage
area as a part of
a firmware
update
procedure
Boot firmware
storage,
configuration
and state data
for IDSDM.
User can initiate a
firmware update
of the IDSDM
device.
There is no
mechanism provided
to iDRAC to write
any SPI NOR area
outside of the
primary IDSDM
firmware region.
iDRAC may issue a clear command
to erase all contents of the SPI
NOR, but doing this will leave the
IDSDM non-functional
