Execute Drive Diagnostic (90h)
This command performs the internal diagnostic tests implemented by the Card.
In PCMCIA configuration, this command only runs on the Card which is addressed by the
Drive/Head register when the command is issued. This is because PCMCIA Card interface
does not allow for direct inter-drive communication.
In True IDE Mode, the Drive bit is ignored and the diagnostic command is executed by both
the Master and the Slave with the Master responding with the status for both devices.
