How to find the “real” IP address of a web site?

You can use the PING utility included with Windows to determine the “real” IP address of a web site. Before using this utility, make sure you are not mapping a host name to some IP address with HostName Commander, because if you do, the PING utility will show the address you’ve set up with HostName Commander, instead of the “real” IP address.

To run the PING utility, click on the Windows Start button, and choose Run from the Start Menu. If you use Windows 95,98, or Me, enter “command” (without the quotes) as the command line to run. If you use Windows XP,2000, or NT, enter “cmd” (again, without the quotes). Click OK and the command prompt window should appear on the screen.

Resolve “Setup did not any hard disks drive” error while installing XP over a laptop

sometimes for compatibility reasons, but also because a lot of people just don't like 7 very much.
The problem that people keep running into left and right is getting to the point where XP starts to install and getting the message "Setup did not find any hard disk drives installed in your computer". This error happens because your new computer has a storage controller that isn't supported natively in XP, usually an SATA (Serial ATA) controller.

If you don't have a floppy drive in your computer (who does anymore), then you'll need to use a process called slip-streaming to integrate the storage drivers into your XP installation CD.
It should go without saying that this is an advanced topic, so proceed with caution.
