I personally worked in Y2K support at the time on PC hardware. Most motherboards we tested worked, but some needed BIOS updates and one model needed a new BIOS fix which didn't exist. We swapped out the bad motherboards, updated software, and had no problems.

In the UK, there were some medical devices (my memory says dialysis machines) that malfunctioned over the issue.

There is an important lesson about the behavior of the media in this. They whipped out people into a survivalist, doomsday prepper frenzy over an issue that could be solved simply by updating BIOS, software, and/or hardware.

With that said, the effort was very expensive because so much software and hardware needed to be audited at every company.
