Philosophy aside, you can sometimes get a PCI MB to boot from a UltraATA

options and chipset driver and OS compatibility can be a problem.
Like someone said, if you stay under 120G, you might not trip any
limitations.
(Even the OSs will have HD size limitations...)
Mixing new with old can get messy fast...
