Table 35. Methodology for Data Input to Memory
How is data input to this memory?
Planar
System BIOS SPI Flash Loading flash memory requires a vendor-provided firmware file and
loader program which is executed by booting the system from a
floppy or OS-based executable containing the firmware file and the
loader. System loaded with arbitrary data in firmware memory will
not operate
LOM Configuration
Data
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. LOMs loaded with arbitrary data in firmware memory will not
operate.
iDRAC6 Controller
RAM
iDRAC embedded system
System CPLD 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 (currently only DRMK utility support)
containing the firmware file and the loader. System loaded with
arbitrary data in CPLD memory will not operate.
iDRAC6 Express
Internal Flash
Not used
System RAM
iDRAC OS: Loading flash memory requires a vendor-provided firmware
file and loader program which is executed by booting 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.
