My idea was to copy BIOS from 4000 series in to 4100 series server. But as I found it is impossible, because both units using different IDE controllers. In this situation the firmware swap will not work.
It is sad, but engineers at Adaptec did really good job to protect their future sale. This unit (4100) has been designed to do not support large hard drives.

The 4000 uses a software raid setup with two IDE controllers, whereas the 4100 is a hardware raid config with four IDE controllers. Very different beasts. The problems lies in the 4100's Promise controller, or rather the driver for it. You would have to dump the intel chip on the mobo that has the OS on it, decompile it, and then create a new driver that would fix the LBA48 bit issue. No one has even been willing or able to get the code off of the intel chip yet. Just wanted to give you a heads up what you are in for.
