How is this memory write protected? How is the memory cleared?
System CPLD
(EPROM) Requires special system-specific
utility. Not possible with any utilities or applications and
system is not functional if corrupted/removed.
System CPLD (RAM) It's not accessible. Not clearable.
iDRAC6 Express
Internal Flash
Writes are proxied through a
temporary iDRAC scratchpad RAM
and not directly made from an OS or
OS application.
Not user clearable.
System RAM OS control. Reboot or power down system.
TPM ID EEPROM
(Plug in module only)
HW read only Not clearable, read only.
TPM Binding
EEPROM
(on China planar
only)
Locked by BIOS from physical access
by anyone after boot.
N/A—BIOS control only
iDRAC6 SDRAM N/A
AC cycle for BMC OS and reset / power off
server for VGA frame buffer.
iDRAC6 FRU
Writes controlled by iDRAC
embedded OS.
EPPID is not clearable.
iDRAC6 Boot Block
Flash iDRAC embedded OS control of the
write protection.
Not possible with any utilities or applications and
iDRAC does not function as expected if
corrupted/removed. Lifecycle log is clearable
only in a factory environment. SEL is user
clearable.
Trusted Platform
Module
SW write protected. F2 setup option.
Chipset
CMOS N/A—BIOS only control.
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.
2.5" Backplane or 3.5" Backplane
Storage Controller
Processor Embedded firmware only writeable
through controlled iDRAC methods.
Not possible with any utilities or applications and
backplane does not function as expected if
corrupted/removed.
