Autotyping ATA disk drives

The move by PC manufacturers to minimize the use of the setup interface has caused Phoenix to change the way PhoenixBIOS 4.0 configures hard drives. In the past, a user would enter setup, select a menu for a specific drive, and then autotype the selected drive. Now systems are autotyping drives as a part of POST. This eliminates the need for a user to enter setup, and it also creates a new environment for autotyping drives. This paper describes a method for reliably autotyping drives as a part of the Power On Self Test (POST).
