Author: andreasf Date: 2010-08-22 02:06:32 +0200 (Sun, 22 Aug 2010) New Revision: 38304 Changeset: http://dev.haiku-os.org/changeset/38304 Ticket: http://dev.haiku-os.org/ticket/6140 Modified: haiku/trunk/src/system/boot/platform/openfirmware/console.cpp haiku/trunk/src/system/boot/platform/openfirmware/console.h haiku/trunk/src/system/boot/platform/openfirmware/start.cpp Log: boot_loader_openfirmware: Enable boot options by keyboard Introduce a non-blocking function for checking keyboard input, and refactor existing code to share the escape key translations. The comment that key-up and key-down result in a zero char is confirmed to apply. If the space bar is pressed, enter the boot menu. If the escape key is pressed, disable the frame buffer and keep showing the usual debug output. Apparently the key press must come after console/keyboard initialization but before the "Welcome to the Haiku bootloader!" line. Closes ticket #6140.
