let the controller and the CPU perform the complete task, rather than having the BIOS issue a series of
commands to affect a transfer to or from the disk drive.
[Auto]: The BIOS will select the best available mode after checking your disk drive.
[Mode 0-4]: You can select a mode that matches your disk drive's timing. Do not use the wrong setting
or you will have drive errors.
