First set the bios in its default setting. Delete the existing installation (although you will have the option to delete it during the installation) and install. Upon the first boot of W2K, it'll do a plug & play search of all your hardware. You will have to follow this sequence and most likely the 4-in-1 driver will not be asked since it'll use the standard dual controller. Video cards and the rest of the hardware drivers will be asked. After the final installation and final boot, check device settings first to make sure all drivers are installed. Check the performance and it you're satisfied, leave it there until you get proficient with the OS. If it feels slow, then check the DMA settings of the HDD and CD-Roms. You can do this in Device Manager and then right clicking on the IDE/ATA Controller Primary and Secondary controllers. If you have to install the 4-1 drives make sure you have the latest since there is a problem with the SB Live and KT133A chipset. If you are installation other softwares and drivers, always do them one at a time and then re-booting the OS each step fo the way to make sure you know you still have a fully functioning OS instead of finding it out later after so many installations and cannot trace your way back to troubleshoot.
