I need to install a second hard drive in my PC tower. This worries me. But it must be done and I don't want to take it somewhere to be done for me. So , I will myself.

Main questions:

a)anyone know of any good computer related websites that have total hand-holding for novices installing hardware? And then all the assigning and master-slave-IRQ-ports-IDE-DMA- aaaaahhhhhhhhh!

b) anyone here have a Dell PC tower? Have any of you done this and are there any peculiarities with Dell that they don't divulge on their tech support site?

thanks alot
