[geeks] (1) PCIe-ish slot? (2) PCI SATA? (3) eSATA?

That does sound like a good guess!  Are there any telltales I can
expect to find (with that slot empty) in the BIOS or on one of the
buses to help me confirm/refute it?

Yes, I would not expect to see both on the same board absent very
unusual circumstances, like a custom-built board designed for a rare
legacy ISA card but otherwise modern.

Thank you!  I'll have to remember that against the day I run into some
rare legacy hardware I want to use.
