I just tried it.  Alas, same result.

Well, I'm just about to file a new PR on this, but I'll refrain if
someone else has alreadyt done so.  Do you have an eisting PR number
on this?

I just tried that (at your suggesting).  Same result.  No change.

I'm not seeing anything like that in my BIOS settings.

Sheeeesh! I literally _just_ bought this new SATA DVD drive, and I went
with SATA because I believed that (a) the world is slowly but surely
switching everything over to SATA and (b) SATA has been around long enough
now that FreeBSD related bugs should have all been shaken out by now.

Please excuse my snarkiness, but... I guess I was wrong about the latter.

Well, I did a search on the PR database for "BTX" and I'm looking at all
those PRs... some of them going back to 2004, which doesn't exactly inspire
confidence about a possible timely fix... and I don't see anything in the
subjects that quite matched up to what I'm talking about.

And ah... while we are on the subject...

If I do file a PR on this, then at long last I'll need to know the answers
to the two questions that have been in the back of my mind for ages, regarding
PRs...

   1)  What do the various severity codes mean?
   2)  What do the various proirity codes mean?

I've never filed a PR with severity "critical" or with priority "high"
because I've always figured that this may be a good way to get the
developers to view _all_ one's future (and past) PRs with a suspicious/
jaundiced eye...  you know... the-boy-who-cried-wolf syndrome.

I don't want to be labeled as a nut case or an incessant complainer, but
for _this_ issue I'm thinking that severity==critical and/or priority==high
may be appropriate.  I mean jeezzz Louise!  If one can't even install from
the distribution CDs/DVDs on perfectly good hardware...  (And it's not like
the whole SATA interface standard is exactly ``new'' or anything anymore.)

So?  Any advice?  Should I stick my neck out and label this PR either
severity==critical or priority==high ?
