What mode is the unit in? Some systems (eg. this Toshiba) save the current power mode across reboots, so if I shut it down having hotkeyed into Low, when I bring it back up, it will still be in Low. > I've fiddled around with the kernel config - in particular the > CLK_CALIBRATION type config options - all to no avail... > > Is there a way of forcing the kernel to beleive the CPU is 100Mhz? - > intead of 50Mhz? If the kernel measures the clock as being 50MHz, then either your realtime clock is broken, or the CPU *is* running at 50MHz. mike
