Installing os on legacy system with usb boot

ok so after hours of searching through google i came across this program called PLOP created by Elmar Hanlhofer

The program is capable of running usb, cd, network and even 1floppy  with no influence to the bios - you can run  this program off as a bootable disk or to be placed  as a mbr to have it like a grub boot- PLOP has support  for both windows and linux i am not sure about mac as i don't own one
