Master/slave/cable select jumpers in a MDD

So I've got a few SSDs I'm going to be using for my MDD and the various OS 9 and OS X installs I want to run on it. However I have never actually dealt with the master/slave/select jump configurations, and can't find particularly clear details on whether this matters for any version of MacOS I want to install. Will they all work fine set to an arbitrary uniform setting? Does the setting change the default boot order?

Master is for any drive that will be the primary or only drive, while slave is for any secondary (or more) drives.

Cable Select tells the computer just to boot from whatever drive has an operating system. If more than one drive has an OS then you'll have to select the correct drive to boot from within the OS itself.

Concerning IDE drives, unless you have some older HDDs it's usually better to set both to CS and let the system deal with it.

SSDs apparently have these jumpers?

I got some SATA to IDE converter boards from OWC (as far as I know no one makes IDE SSDs and for later use it wouldn't make much sense to buy them anyhow), the jumpers are on those.

Thanks for the info! For my needs CS will probably be the way to go then.

I've been dealing with IDE drives long enough that I can't get used to this new fangled cable select thing :)

I just set one to master and one to slave-it doesn't matter which is which, just as long as you don't have two of the same thing on the bus.

Aside from that, just set both to cable select and you should be good to go in the MDD.

When all else fails - cable select! :)
