Getting any legacy OS to run on modern hardware is very hard. For example, in my case, BeOS has no EFI boot capability, has a serious RAM restriction, doesn't really like anything past a P4, and has no drivers for anything but legacy hardware (like, no modern storage drivers - IDE only, no SATA unless there is legacy BIOS emulation.) A lot of this is able to be worked around with various hacks, but with 86Box, it will run the OS as is it was on the actual hardware, so it just makes it a no brainer. You can then also use it to emulate old PC hardware on other processor architectures - like ARM.
