Re: IDE Card

[Richard <degage teleport com>]

I have seen something similar with an attached card.  I believe the two
IDE ports are simply sharing the same interrupt and will be able to keep
your devices separate.  I read somewhere (an Anandtech article, if I
recall) that it identifies as a SCSI device so it can be found in the
boot-up sequence of your BIOS but functions as an IDE controller
regardless.  That is, how it is identified and how it is used seem not
to necessarily be intrisically related.  I think Triones Technologies is
an identifier for a Highpoint chip.  I also read just recently that the
80-wire cable used with ATA66/100 devices is "cable-specific," that is,
it separates the devices.   I have seen one document that insists that
the drives should be jumpered as "cable select" rather than as master
and slave as that determination would be made by the cable and card.  I
tried this with my setup and saw no difference that I could attribute to
it, and it was working fine before, so... I went back to the original
jumpers.  Another article suggested (referencing raid really) that the
original higher performance speeds were SCSI and have merely been
adapted for IDE and this is the reason they are identified as SCSI but
function as IDE.  So far as this goes, I merely report.  I don't think
Linux will have a problem here.  The drives will be identified as
(assuming you have two IDE controllers on board) hde, hdf, hdg, hdh, in
the usual order: first or primary controller on the card, master and
slave, then the secondary.  I would put the drives on separate cables if
they are different speeds as I read somewhere that two drives on the
same cable, of different speeds, will cause the system to fall back to
the slower speed for both.  Richard
