HP Omnibook XT6050, XT/VT6200 Removal and Replacement 2-27
Reassembly Procedure
Note: Reprogramming the BIOS IC
A new BIOS IC contains only enough basic programming to enable the notebook to boot. After
installing a new motherboard, you must reprogram the BIOS IC, preferably with the latest BIOS—
see page 2-29.
1.
Transfer the following components from the old motherboard onto the new motherboard:
•
SDRAM module
•
speaker assembly
•
display interface PCA
•
volume PCA
•
CPU module
•
PCMCIA socket
•
mini-PCI card #1 (if present)
•
mini-PCI card #2 (if present)
2.
Follow the reassembly notes in the section entitled “Removing the Motherboard or Bottom Case”
on page 2-25.
Note: After Replacing the Motherboard
After replacing the motherboard, you must use the Service Utility floppy disk to store the system data
and display information in the EEPROM on the new motherboard.
1. Connect a floppy disk drive module: insert the module into the notebook, or connect it to the
computer using an F2008 external floppy drive cable.
2. Plug in an AC adapter.
3. Insert the Service Utilities floppy disk in the floppy drive.
4. Turn on the computer.
5. If you hear 5 beeps, press F1 to update the display data stored on the motherboard. Let the
computer reboot and go to the next step.
6. Select the Serial Number option from the boot menu.
7. If you successfully stored system data on the floppy disk before removing the old motherboard,
type A for the automatic update. This restores the old system data on the new motherboard.
If you did not store system data, type M for the manual update option. Enter the serial number from the
bottom of the unit—you may have to contact an HP support center to do this.
