As Matthew pointed out, the 'message' about not finding the cable (on a
SATA port) is superfluous/gratuitous/irrelevant.
I was more thinking about the wrong side issue on normal PATA ports :)

Well - I do plead guilty to cutting-off the endian-ness pin on the MB
and reversing the cables sometimes when one drive is atop the MB
and the other at a distance. But only 'til I can get back to the office
and fab a custom cable. ;-)
But w/r the original post - only the Promise Fastrak S-150 TX2 Plus
even has a PATA connector, (ports 1 & 2 are SATA, 3 is PATA)
- and it was not in use.
One of the HPT's OTOH, was pure PATA. So we have two separate issues:
- driver reporting of non-80-pin cable when there IS one (approved by
MB BIOS)
- driver reporting of non-80-pin cable when it is not germane (pure SATA).
My only concern was whether the driver forced a 'downshift' to PIO3,
which is
*says* it does do, or utilized the higher-speed UDMA protocol and signalling
with ECC.
If that is not ascertainable from the source code, I will put a dual-trace
'scope on it and confirm from the waveforms.
