Abstract: PROBLEM TO BE SOLVED: To appropriately set a device controller having two operation modes corresponding to the installation state of a device driver.
SOLUTION: The device controller is operated in the two operation modes of an old operation mode in which it is operated by an old device driver and a new operation mode in which it is operated by a new device driver. For an OS, there is the case that the old device driver is introduced but the new device driver is not introduced. A BIOS sets the device controller to the old operation mode and activates a computer. In the operation environment of the OS, the presence/absence of the new device driver is inspected. When the new device driver is detected, control is shifted to the BIOS and the device controller is set to a new operation mode.

解决方案：设备控制器在旧操作模式的两种操作模式下操作，其中它由旧设备驱动器操作，并且由新设备驱动器操作的新操作模式。 对于一个操作系统，有一种情况是引入了旧的设备驱动程序，但没有引入新的设备驱动程序。 BIOS将设备控制器设置为旧的操作模式并激活计算机。 在OS的操作环境中，检查新设备驱动程序的存在与否。 当检测到新的设备驱动程序时，控制转移到BIOS，设备控制器设置为新的操作模式。 版权所有（C）2007，JPO＆INPIT
