Usually, I would prefer USB. However, I used to have some older systems

IIRC, that was true with the PII-class Celeron with "Y2K compliant"
motherboard.

UPDATE:

The solution, strangely enough, was to remove everything from every port
possible, nary even a mouse, with just a mechanical keyboard in place.

Then, after POST, an F10 opened to the BIOS setup where I was able to
enable AMD-V, which then enabled Android emulators to work on Windows
inside of a virtual machine (in my case, inside of VirtualBox).
