Logic PCA Board
(HP Authorized Service Providers Only)

Electronic Serial Number

The OmniBook 800 (F1360 only) is shipped with an electronic serial number programmed in
EEPROM on the Logic PCA Board. This built-in serial number will help MIS managers in
tracking assets and software configuration. Serial numbers can also be used for security and in
tracking lost or stolen notebooks. The Desktop Management Interface (DMI) TopTools
application shipped with the OmniBook can be used to read the serial number locally and across
a network.
Programming the Electronic Serial Number
All replacement Logic PCA Boards will arrive with a temporary serial number programmed in
EEPROM. The following procedure provides the steps necessary to reprogram the electronic
serial number.
1. After installation of the replacement Logic PCA Board and upon reboot, the OmniBook will
halt with this prompt:
INVALID ELECTRONIC SERIAL NUMBER
PRESS ANY KEY TO CONTINUE
2. After a key is pressed, the OmniBook will continue a normal boot process. The HP
Authorized Service Provider must program a valid serial number before the OmniBook can
be shipped to the customer.
3. Run the ESN.EXE program located in the c:\omnibook\diag directory.
4. The ESN program will prompt for a valid serial number.
5. Enter the serial number located on the bottom of the OmniBook. The ESN program will burn
the serial number into EEPROM.
Overriding an Incorrect Electronic Serial Number
If an incorrect serial number is inadvertently burned into EEPROM, it can be corrected. Perform
the following steps:
1. Run the ESN.EXE program located in the c:\omnibook\diag directory.
2. The ESN program will prompt to confirm that the serial number is incorrect. It will then
generate a five (5) digit number key.
3. The HP Authorized Service Provider must contact Hewlett-Packard Technical Support at this
point.
4. HP Technical Support will ask for a CZ authorization number and the five (5) digit number
(from step 2).
5. HP Technical Support will provide a validation key to the HP Authorized Service Provider.
6. Enter the validation key. This will reset the electronic serial number with a temporary
number.
7. Follow the above steps in Programming the Electronic Serial Number to enter the correct
serial number.
Note, updating the BIOS on the OmniBook will not affect the electronic serial number.
