FWIW, the config file I ended up with is below. For a good laugh, compare it with the 300-line monstrosity your favorite distro produces auto-magically. Despite grub2 documentation to the contrary, 'keystatus --shift' does not always return true if the shift key is held down. In my testing it only returns true if shift was up when grub started and _then_ was pressed and held down. If you press shift before grub starts (and hold it down) then 'keystatus --shift' returns false. [Maybe this is HW dependent?] That's why I added the double "A above middle C" beep followed by 1 second of silence: provides a window during which you can press the shift key. I would prefer it if you could just press and hold the shift key immediately after power-on, but it'll do. ---------------------------------------------------------------------- set root=(hd0,3) insmod play play 6000 440 10 0 20 440 10 0 100 set default=0 if keystatus --shift; then set timeout=-1 set timeout_style=menu else set timeout=0 set timeout_style=hidden fi menuentry "Windows"{ [...] } menuentry "Recovery"{ [...] } ---------------------------------------------------------------------- -- Grant Edwards grant.b.edwards Yow!
