Software write protected
Not explicitly protected but special
applications are needed to
communicate through the LOMs to
reprogram this ROM
Protected permanently by hardware
n/a
Requires special system specific
utility
Not accessible
Writes are proxied through a
temporary iDRAC scratchpad RAM
and not directly made from an OS or
OS application.
OS control
HW read only

Not possible with any utilities or applications and
system is not functional if corrupted/removed.
Not user clearable
Not clearable
iDRAC reset
