I'm really confused here. Which one is the master connector and which one's the slave? AFAIK the middle connector was the slave. And what about the cable select setting. A good explanation will be appreciated!

Plus, would using an 80pin IDE cable for the burner & dvd drive on my secondary ide channel be bad for them?

The cable select follows the positions on the cable, and yes the middle is the slave. Also, dont bother with an 80pin for cd drives etc, as they dont even use the full speed of a 40 cable...

with the cable thing the 80pin is always better for everythign especially hard drives but since cdroms aren't fast enough to barely make use of a 40 it doesn't really matter but with harddrives its REALLY important. Also, cable select automatically set the drive to master and slave for you, you want this setting because it simplifies things and is ususally more stable with newer board like asus bios. as far as the connectors the cable looks like this
A----B---------C
A = Master
B= Slave
C = Motherboard
This is with cable select on, if you use jumpers to configure master and slave you gotta still keep it in that order to get the best performance.

With jumpered drives, the order should not make a difference in performance. The drives are accessed by an address bit in the ATA spec, 0 for master 1 for slave. When the drive is accessed, the drive responds only to commands issued with it's address bit referenced.

Okay, thanks for the info guys. Some people have told me that putting them on as cable select improves performance, is that true?

How do you discern the difference between an 80 pin cable, and a 40 pin cable?

Just look at it. The 40 pin cables usually only have black connectors, and the wires a pretty thick. The 80 pin cables usually have a blue connector on one end and sometimes a white one in the middle, and the wires are much thinner.
