OK, thanks for the info!
Is there a command I can run in the PuTTY terminal to find out what kind of BIOS
the eMachine uses?

This is what I see concerning the internal disk (lines wrapped by newsreader):

$ sudo lsblk -o UUID,NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL,MODEL
UUID                                 NAME   FSTYPE     SIZE MOUNTPOINT

Since there are a lot of port forwards to this box I need to keep the IP address
to avoid reconfiguration of all of that. May have to change the MAC/IP
reservation on the router.

PS:
Today I bought a UPS (APC ES-700), now planning the installation. I have counted
18 consumers hooked to various multi-outlet boxes...

I will hook at least the following to the UPS:
- Internet fiber interface box (provided the other fiber end is powered)
- Main ASUS router
- IP-Phone interface
- Two network switches
- Synology NAS DS-212j
- Any number of Raspberry Pi boxes

With this I should keep the network up even in a shorter power outage and the
Ubuntu Server running happily behind the network router.

Still I think I should upgrade the hardware, though.
Ubuntu has limited support for older hardware, at least it says so when you
install/upgrade an LTS release...
