Hi William I have helped build several barebones system here lately. Most of them seem to go pretty smooth if all the related equipment is also new. I noticed you say you have a 6X CD which came to my attention. A few months ago I was upgrading via the barebones type situation and tried using the existing 10X CD and started having strange problems. Upon further investigation into some of the README files it was pointed out that some older CD ROM's especially those that use the Autoexec.bat to get recognized have trouble getting along with the drivers for PCI Bus Master IDE Controllers. In my situation if I had the mother board operate in the DOS compatible mode it worked ok. But as you probably know, by looking in the System Properties, underneath Performance, it would let you know the system is not optimized. Being CD Roms are cheap, the easiest fix (to get the computer optimized) was a newer CD that windows would detect and not have to use the Autoexec.bat. Don't know if you may run into this or not but just FYI incase.

I would like to pull the 6X cd-rom drive, sound card, modem, PCI video card, and hard drive out of my Micron P133 system and install them into the new one (at least for now). Since the new system will use alot of the old hardware is there a chance I will be able to leave everything on the hard drive and just plug it into the new system. Everything is working good now, and that doesn't happen very often. I doubt it's that easy.
