[G4] How to set your hard drive to master

[jennifer friede]

Hello,

I have a PowerMac G4 and my master hard drive is set at 20 GB when I  
originally purchased. I want to upgrade my master hard drive. I  
purchased a 250 GB Maxtor ATA/133 7200RPM 16MB. My computer doesn't  
recognize the drive when I installed the 250 GB hard drive in P2.

Does this have something to do with the jumper cable? I'm confused  
with the master/slave part. If anyone can help me out with examples  
or descriptions or links. I've done research online and found a lot  
of information but I couldn't understand what I'm not getting at.

I have already purchased the same hard drive for my slave and already  
installed the proper firmware to recognize the capacity of the GB size.

Thanks,

Jennifer
