Server BMC (Baseboard Management Controller) also
known as “iDRAC Express” Internal Flash Details
Size 1 GB
Type: [e.g. Flash PROM, EEPROM]: NAND Flash
Can user programs or operating system write data to it
during normal operation? No
Does it retain data when powered off? Yes
Purpose? [e.g. boot code] iDRAC Operating System plus Managed System
Services Repository (i.e. Unified Server Configurator,
OS drivers, diagnostics, rollback versions of various
programmables)
How is data input to this memory? iDRAC OS: Loading flash memory requires a vendor
provided firmware file and loader program which 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.
How is this memory write protected? Software write protected
