I received a PM from PumaUK stating that he was forced to delete my first Post re this new update, and at one stage, he was quite correct.
LiteOn did indeed offer an incorrect download (as I found out for myself at the time).
However, by the time I made my first Post, they had corrected the situation and I have
since downloaded and successfully installed and used BIOS (Firmware) version QP5A (I was on QP53).
I have no idea what the changes are.
Hope this clarifies the situation
Go here and search (Optical Drives) for your DH-20A4H update download (QP5A.Zip)
