protected
backup of
critical System
BIOS code, EC
rmware, and
critical PC
conguration
data for select
platforms that
support HP
Sure Start.

Data cannot be written to this
device via the host processor.
The content is managed
solely by the HP Sure Start

Real Time Clock
(RTC) battery
backed-up CMOS
conguration
memory
256 Bytes No Yes Stores system
date and time
and noncritical
data.
RTC battery backed-up CMOS
is programmed using the
Computer Setup (BIOS), or
changing the Microsoft
Windows date and time.
This memory is not write-
protected.
Controller (NIC)
EEPROM
64 KBytes (not
customer
accessible)
No Yes Stores NIC
conguration
and NIC
rmware.
NIC EEPROM is programmed
using a utility from the NIC
vendor that can be run from
DOS.
A utility is required to
write data to this memory
and is available from the
NIC vendor. Writing data
to this ROM in an
inappropriate manner will
render the NIC non-
functional.
DIMM Serial
Presence Detect
(SPD)
conguration data
256 Bytes per
memory board,
128 Bytes
programmable
(not customer
accessible)
No Yes Stores memory
board
information.
DIMM SPD is programmed by
the memory vendor.
Data cannot be written to
this memory when the
board is installed in a PC.
The specic write-
protection method varies
by memory vendor.
System BIOS 9 MBytes Yes Yes Stores system
BIOS code and
PC
conguration
data.
System BIOS code is
programmed at the factory.
Code is updated when the
system BIOS is updated.
Conguration data and
settings are input using the
Computer Setup (BIOS) or a
custom utility.
NOTE: Writing data to
this ROM in an
inappropriate manner can
render the PC non-
functional.
