I have two hard drives on my computer,how do I get the second one configured to work

Set the two hard drives on the same cable, set one as a master and the other as the slave using the jumper settings. Format and partition the hard drives. Install the OS on the first partition and the other will be picked up automatically as the D or E drive

(For the same IDE cable)
Separate them by jumper.
One is master.
And the left one slave.
( the configuring steps are on hard disk )

Make sure that you configure the jumpers
