Cdrom Primary Slave?

[Scorpion]

What's Up?

OK, So recently I revived an old computer, I'm going to use it purley for burning my pirate games (yyaarr!) Now I have yet to install an os on it, First of all I need to be able to boot from disk, And after inserting a new cdrom it has switched the primary slaw drive from the oldone to the new one.

Which isn't want I want, So my question is, how'd I switch the old cdrom back to being the primary slave again?

I heard it's somthing to do with hose jumper lead cables?

Thanks Bye.
