You could install a bootloader that uses a conf file, and have a script that edits that and then reboots into your chosen OS. Of course, down that road may lie much frustration as a badly-written script can cause you to reboot with a ramdisk or some such and edit by hand. > Thanks > > Jonathan Steel
