If someone buys a 160GB field replacement unit for the 4100, it supposedly comes with instructions as well as being mounted on a drive sled already ( I need 4 sleds and a front bezel) but I wonder if they give a bios update? Has anyone who tried running at least 3.805 or 4.0?

You are right about Promise chip.
My idea is to retrieve Bios form model 4000 and burn it in to model 4100.
To do so without removing Flash memory, I need to get thru Intel Chip.
I do have equipment to read this Flash memory, but I need properly address Intel chip to be able to retrieve Bios.
For this purpose I'm looking for picture of controller used in model 4000. Can somebody get this picture for me?
Also if there is somebody who knows differences between controller used in 4000 and 4100 series please let me know.
Generally, I'm trying to get full access to controller thru black 40 Pin connector J8 used by manufacturer to upload entire controller and perform diagnostic.
I see big challenge to break 137GB barrier by enabling full access to flash memory.
