I've got a few other 5.3-Stable (5.4-PreRelease) PCs
here. On these machines I get:

$ grep hint.ata.0 /boot/device.hints
$ grep hint.ata.0 /usr/src/sys/i386/conf/GENERIC.hints

So it's already there! I suppose it's the same with
the 5.3 installation floppies, or isn't it?

Or would me setting it manually at the loader prompt,
have a different effect?

I've got not really a choice here. This is a 10 year
old Pentium-1 PC, which I would like to use. I'm not
a hardware expert, but your advice would mean to
throw this PC away? Or can I replace the ATA
controller easily myself?

I have already put this machine under moderate load
and recompiled/installed a new world/kernel without
any problems. Apparently 4.11 knows how to bypass
the flaws of this buggy ATA controller. At least
that's my impression.
Would 5.3 or 5.4 do this as-good here?
