    Ah, okay, that figures. Curious that most clones don't do that.

    Yes it will. It will also work with low-density disks in high-density drives.

    You can also boot from a DR-DOS 7 high-density boot disk, even with no BIOS support. This will then allow you to access any other HD floppy disk.
