Modified Files: src/sys/arch/i386/stand/boot [netbsd-5]: boot2.c Log Message: Pull up following revision(s) (requested by he in ticket #1872): sys/arch/i386/stand/lib/bootmenu.c: revision 1.11 via patch sys/arch/i386/stand/lib/bootmenu.h: revision 1.3 via patch sys/arch/i386/stand/boot/boot2.c: revision 1.59 via patch Two changes for the i386 boot loader related to the boot menu which can be defined in boot.cfg: * Add a "menu" command which re-displays the menu and initiates the timed countdown * Use any default command defined in boot.cfg as default args if the user runs "boot" with no arguments This is useful in circumstances where you e.g. need to interrupt the normal boot process to switch to serial console, and where simply "boot netbsd" is no longer sufficient (e.g. as with install media which needs the miniroot kernel module loaded).
