I haven't had a chance to look farther though. IDE is less of a problem normally. In the LinuxBIOS case it may become measurable, and the initial drive spinup has to occur before the firmware responds. (If I understand it rightly most of the drive firmware is on the disk). For the spin up/down the IDE folks put it in the drives which makes life much simpler - 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/
