What is a PDK folder?
What does each of those tools need. Need they special drivers or so or do you just need a dos bootdisk? If not, it will be probably easier to start from an installation of freedos installed on the harddisk of a virtual machine.
The freedos image of ubcd is bootable of course. If you have a 2.88M floppy disk laying around, you could boot from it.
After reboot, when I select to boot from freedos, it runs until "Loading boot sector...booting....(next line) FreeDos" Then it stops running. Do you know why?
I don't know, but there must be something wrong. Have you tried to boot the image directly in a virtual machine? See if that works.
