SATA has a different electrical interface, but otherwise speaks the same
protocol as the older (P)ATA protocol. Converters are cheap and readily
available.

So yes, you could stick a SATA disk in your old 5170, assuming that the BIOS
doesn't immediately faint when presented with a very large disk.


I think there are two barriers to that. No sata is a cards. And BIOS of
that era still required you to tell it the chs for the drive...
