ABSTRACT:
A CMOS memory stores DPMS-Enable/Disable data set by the user. When a display power save request has been issued from an operating system or an application program, the VBE/PM of a VGA BIOS determines, with reference to the DPMS-Enable/Disable data, whether or not a DPMS function is enabled. The VBE/PM executes the DPMS function including the interruption of the supply of horizontal and vertical synchronization signals, if the DPMS function is enabled, and does not execute the DPMS function if it is disabled. Thus, the execution of the DPMS control function can be allowed or prohibited in accordance with the contents of the DPMS-Enable/Disable data.
