Hi Paul,

(Are you Frodo?)

Don't think Paul is. I'm certainly not.

Your post was really helpful. Does an 80-wire cable still have a
40-pin connector, just like a 40-wire cable does? The IDE cable I
currently have was installed in 2002.


There are 40 functional wires in both the 40 and 80 wire ribbon ide cable.
Both have a 40 pin connector.

The purpose of the remaining 40 wires in the 80 wire ribbon cable was
previously explained.


I found an AOpen manual online; it's generic for its DVD Rewrite
drives. It said that having the DVD set as Master is "recommended"
and would be "best" -- but didn't tell why. Currently I have it set
as secondary. The Manual showed configurations for sharing DVD & HD
on the same IDE cable. It did not show any DVD + CD on the same
shared IDE cable. Will the Mitsumi 4x from 1999, which is now set as
Master, is not going to limit the new AOpen DVD drive's capabilities?


All I know is the older 99 and before models may not work on motherboards
built in the last 3 years. You may be on the fringe of that. Try the
Mitsumi alone first and master. If it doesn't show up in the bios summary,
it will not work. If it does, try pairing with the Aopen.

Some DVD/CD players/burners may not cooperate on the same ide cable.

What has secondary have to do with master?

Primary and secondary refer to the ide ports on the motherboard and their
controlling chipset on the motherboard. Master and slave refer to an ide
device relationship on an ide ribbon cable connected to an ide port. The
port can be primary, or secondary.

I've seen some IDE cables online that are not flat ribbon cables; they
are round, so easier for me to fiddle with, plus they leave more air
circulation space inside the tower. Do you think they are worthwhile?

Depends on who you talk to, and their experiences. I've seen both good and
bad round cables 80 wire version.

Additional air circulation may be a good thing if its affecting some
component's cooling function positively. This is not always true.

If I get an 80-wire cable that supports cable select, then I don't
have to worry about Master/Slave ever again, right?


Its the motherboard via bios, and the ide device itself that must support
cable select for that to work.

Yes, you still have to consider master and slave. The ide device on the end
of the ide cable has to be master, the middle connector is the slave device.
Some ide devices demand master to function. Some ide devices won't function
correctly on the same ide ribbon cable. In some cases, cable length between
the master and slave may be insufficient if mounted too far apart. I have
seen instances where a master (set as master, not cable select) worked on
the slave position of an ide cable, nothing else connected. This typically
does not work, its called a stub connection.
