With existing RAID, how to jumper extra IDE drives?

[Andrew J. Rozsa]

I am starting with 865PEDAP MoBo and a SATA RAID already installed and
functioning properly. The RAID is connected via PCI SATA Adapter. The
system is booting on the RAID (OS is XP-SP2). I am adding drives from
previous system. These are ATA IDE drives. If I leave the RAID alone,
how do I jumper the additional IDE drives (drives 3 & 4)? The 2 IDE
drives are 10-pin drives so they can be set to Dual Slave. Also, on
the MoBo one of the IDE connectors is red and the other is white. Any
significance to the color? Does it matter which do I plug where? A
floppy drive is already connected to the red IDE connector.

Sure would appreciate help with this. My son is "inheriting" the old
Dell and is nagging me to death to finish the "homebrew project."
Best,

Andrew

Best to jumper them both cable select and use an 80 wire cable select cable.

If you dont do that for some reason, one drive on a ribbon
cable should be jumpered as master and the other as slave.

The 2 IDE drives are 10-pin drives so they can be set to Dual Slave.

That isnt right, master and slave applys to a particular
ribbon cable, not to the system as a whole.

Also, on the MoBo one of the IDE connectors is red
and the other is white. Any significance to the color?

One is likely the primary ATA controller and the other the secondary.

Does it matter which do I plug where?

Not in your case. Might as well have them on the primary tho.

A floppy drive is already connected to the red IDE connector.

A floppy drive isnt normally ATA IDE.

Thank you, thank you. Didn't even think about it this way. Like you
point out, one had better use Ultra DMA (80-Conductor) IDE/ATA Cables
http://www.pcguide.com/ref/hdd/if/ide/conf_CS.htm. I was going to say
"but the drive has only 40 pins," then I read that "the new cable has
80 conductors (wires)--it does not have 80 pins on each connector,
though, just 40. This means that the new cable is pin-compatible with
the old drive." Phew.

There is a nice and easy article here
http://www.unixwiz.net/techtips/ide-cable-select.html about making
your own cable-select cable (hint: you have to cut the 28th wire).

Learning something new every day. Just as I hoped when I started this
"project."

Thank you, Rod. I am grateful and definitely wiser.

cable.

Good luck with that scenario, cable select is the most unreliable way of
doing this. It could work if you on a DELL or HP or something like that.

The position of the drives are very specific to the system and bios, little
to do with the cable. Except where they are located on said cable determines
their designation (master/slave) instead of the jumpers. If you even have a
2 position cable on hand. AND DON"T MAKE YOUR OWN CABLE> that's a recipe for
disaster

Thats for 40 wire cables. It shouldnt be necessary to do anything
to 80 wire cables, they should all be cable select cables. That
does not prevent you from using master/slave if you want to.

Have fun explaining how come its the default with new systems now.

You're massively confusing cable select with 40 wire ribbon
cables and cable select with modern 80 wire cables.

The position of the drives are very specific to
the system and bios, little to do with the cable.

Wrong again. Master and slave only apply to a particular
ribbon cable, nothing to do with the bios or system.
