Development Kit
6.2.4
Processor Sockets
The processor is keyed so that it fits into the socket in one particular orientation.
6.2.5
Firmware Hub (FWH) BIOS Socket
The system boot ROM is installed on the ATMEL AT49LW080 or SST ST49LF008A
Firmware Hub device. The FWH is addressable on the LPC bus off the Intel
®
6300ESB
ICH.
The FWH or BIOS flash memory fits into the 32-pin socket U2H3, giving you the option
to remove and reprogram it without the use of soldering equipment. There is also a
flash utility that is supplied with the BIOS that can be used to program the FWH. This is
the recommended way to program the FWH.
There is only one correct orientation for the FWH to be placed into its socket. Line up
the circular marking on the FWH, denoting pin one, with the arrow marking on the
evaluation board socket.
Note:
An additional BIOS flash memory is included in the development kit. This BIOS chip
must be installed in the platform when the Intel
®
Core™ Duo Processor is used. See
section 2.6 for more details on how to replace the BIOS chip.
6.2.6
Battery
A type 2032, 3 V lithium coin cell battery is used in socket XB5G1 on the evaluation
board. The battery is held in place by a metal arm. To remove the battery, gently push
the metal arm and remove the battery.
Warning:
Risk of explosion if the lithium battery is replaced by an incorrect type. Ensure the
correct type of battery is selected and installed correctly before turning power on to the
board.
