It sounds like you are already installing the operating system. Did you look at the instructions here:

If you unzipped the driver package, taht is a good start. But it looks like it is in .EXE format. If so, that is why XP is not finding the drivers. For XP to find them, they would have to be .INF files and .DLL or .DRV type files.
I would suggest that you skip this part of setup and let XP finish installing. After the install is done, start the computer. Find the .EXE file on the disk or copy it to the Desktop, then double-click the .EXE file. It will install itself.
Until the drivers are installed, the colors on the screen might look funny, but that is okay. You can change the resolution and color depth after the drivers are installed, if this doesn't happen automatically.
Note: if I guessed wrong, and there is a .INF file on the disk, you may need to browse the disk in the driver installation window to the folder the .INF file is in. Then XP can find it.
If this is still wrong, you might not have the right drivers for your computer. Make sure to get the right driver package for your motherboard chipset.
I hope this helps you. :)
