If you change the boot priority in the BIOS to have the IDE drive as the
system drive for the install, you will not affect anything on your Vista
boot process. Either way you are going to have to add the legacy system to
your Vista boot process either with VistaBootPro, or the repair startup of
the Vista install process.
Not sure what would happen otherwise, as XP has to write the boot files on
the system drive.
