Firmware for (HP) Lite-On: hp BD E DH12E3LH EHDC

Does anyone know what firmware will work on the above Lite-On drive. It was mfg’ed for Hewlett Packard computers. Because it was not a retail drive, Lie-On does not have firmware for it. PLDS SmartPack could not come up with one for it. If you know of one and it needs to be cross-flashed to load, I need instructions on how to do that. I tried a link on a thread for that, but the link is no longer working. Thanks guys for any help. Cross-flashing info needs to be for a dummie like me.
