Isn't the bigger risk that if you include the HPA in your block device, you'll overwrite your BIOS there? At least that's what happens on some thinkpads. It'd be nice if we left it as the BIOS leaves it by default, but make a straightforward way to enable/disable/alter the HPA region from software. (if there's already a straightforward way, feel free to clue me in -- but the default should almost certainly be to assume the HPA is set up correctly, shouldn't it?) -- Peter - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
