    Per HDD, there can only be four partitions; each can be bootable

    BIOS finds the first HDD with an active partition and looks for the boot sector (not the MBR) in it. If found, it reads the boot.ini for the data.

    Therefore, if HDD#1 is bootable, then the boot.ini can control what gets booted - -
    even other partitions on different HDDS

    You can boot an OS on a slave drive if the master hard drive has a bootloader. Physically swapping jumpers on drives is not the best way to boot off a slave drive.
