When you first start your machine enter into the BIOS and make sure the drive was identified properly. Generally it's the [del] button that gets you into the BIOS but sometimes it's F1 or F2. You should be able to see some kind of message on the screen when it first posts indicating what you need to push.

Once you're in the BIOS you'll want to go into standard CMOS where you should see something like this:

If your drives are showing up properly then you did it right. If they aren't then you've got some troubleshooting to do. First of all look go back to the front page in your BIOS and select integrated peripherals. Make sure that both IDE channels are enabled. Most likely you set your jumper wrong.

Partitioning:

Retail packaged hard drives will have an install disk for you. If this new drive is going to be your main drive then use the partition app that is built into Win 2k and XP. If your using win 9x (why?) then you'll want to checkout bootdisk.com and find something that'll cover your needs. You'll need to fdisk this. Since most of people are using 2k or XP I won't bother covering all the steps in fdisk.

If this is being installed as a secondary storage drive for Win2k or XP then you can go into the built in utility called disk management. Go into the control panel -- go under administrative tools -- Computer Management -- Storage -- Disk management

Look on the bottom right and you'll see something that looks like this picture. The disk with all of the unallocated space is what you're after. Right click on it. Select New Partition.

A wizard will pop up and walk you through this process. If this is a secondary drive then you're obviously after pure storage space so just make it a primary partition and allocate 100% of your space to it.
