Abstract
The present invention speeds display device detection during system boot by utilizing the simple boot flag register and an additional indicator to determine the display device configuration detected during the previous system boot. If the display configuration has changed since the previous boot, then the changes are noted and, when appropriate, recorded for use during subsequent boots. If the configuration has not changed, then the display device configuration from the previous boot is still accurate, and it is therefore not necessary to query each output port during the current system boot.
