1200 LUTs

Type [e.g., Flash PROM, EEPROM]:

Internal Flash

Can user programs or operating system write

data to it during normal operation?

Purpose? [e.g., boot code] System power sequence control.

How is data input to this memory?

Factory only. Not customer updatable.

How is this memory write protected?

Software write protected

Server CMOS (Complementary Metal-Oxide

Semiconductor) Memory

Details

Size: 512 Bytes

Type: [e.g., Flash PROM, EEPROM]: Battery backed NVRAM

Can user programs or operating system write

data to it during normal operation?

Purpose? [e.g., boot code]

RTC & Configuration settings

How is data input to this memory?

F2 Setup Menu during POST

How is this memory write protected?

N/A

How is the memory cleared? Jumper on motherboard can be used to

Ethernet Controller Configuration Data

(planar)

Details

Size:

4 Mbits

Type: [e.g., Flash PROM, EEPROM]:

Flash

Can user programs or operating system write

data to it during normal operation?

Purpose? [e.g., boot code] LAN on Motherboard configuration and

firmware

How is data input to this memory? 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 with arbitrary data in firmware

memory would not operate.

How is this memory write protected? No explicitly protected but special

applications are needed to communicate

through the LOMs to reprogram this ROM.

Server System Event Log Memory / FRU

Details

Size:

32 Kbits

Type: [e.g., Flash PROM, EEPROM]:

SEEPROM

Can user programs or operating system write

data to it during normal operation?

Purpose? [e.g., boot code]

motherboard electronic product identifier

How is data input to this memory?

factory and iDRAC embedded OS
