Using UNetBootin, I've made a bootable DOS 6.22 usb drive from a dos 6.22 bootdisk ISO.
The drive is a 4gb FAT32 drive, formatted on a windows machine.
Is there anyway to boot a 2013 Mac Pro from this drive? I assume, if it's even possible, I'll have to find a way to enable legacy boot.
Right now i put the drive in, hold down option, power up the machine, but it never lists the USB drive as an option to boot from.

Macs don't have a 'legacy boot'. They're EFI. They will boot from GUID only. As already mentioned, a VM is the way to go. – Tetsujin – 2018-09-20T07:11:31.833
