In all build I can loading b3530 and b4023 (on HDD) or b5845 (loading from USB) the Network adapters not detected, I do not know what happened and I would like to understand it.
I do not change any hardware. The network settings just disappeared (DSS does not detect a network adapter PCI, no IP etc. - I added new network PCI card to check if onboard card could damaged or spoiled).
I wondered if I can restore saved settings in console but I could not find such option, so I do not what can I do to recover normal working in build b4023.
Now I have loaded in HDD b3530, b4023 and not loading b7337.

It may be that the newer builds have newer drivers and is best to go back to an older build to work with your older hardware.

What is the specific hardware not showing up? model, etc...

Something happened...
Indeed, the second connected network PCI card was incompatible. So I plugged another PCI compatible adapter with chipset RTL-8139C and after turn power off the serwer and reloading DSS console I just saw the both network adapters in DSS console: 1. the lost earlier adapter onboard RTL-8111DL (found itself, also I see the driver of adapter, now) and 2. the second network adapter I just connected. Then I had to recover data on the storage disk by upload and restore saved settings. Now working normal.
I still have one problem I wrote the above: I can not upload in webGUI (Maintenance - software update) any System software update (any build) I downloaded to the PC from website open-e.com. How I can do it? I do not want install. Newest build I can loading is b5845 (I can not loading next b6335,b7337-black screen with "Loading..."), but DSS download only b7337 by update downloader. So, I want upload b5845 from my PC (in LAN) by webGUI because I do not want use the installer (with romove all system data from disk).

I do not want use the installer (with romove all system data from disk).

The installer will only reformat the boot media, not the data area.
Do a new install and restore from settings.cnf file saved previously.
