About the boot/resume latency of Boot device...

Post by liaoo »

Hi all,

I have some questions about the boot device...(We want to develop storage device and use it as the "boot device"...) Maybe you can give me some comments.... :)
  • 1. Is there any document or spec defining the max boot latency ? Here the latency is calculated from Power button is pressed to Windows Logo appearance
  • 2. if we complete our own storage device and want to use it as boot device, then how do we know if it is "qualified" regarding the speed ? Here the speed indicates the device's response to host's requests...
  • 3. The same question is applied to the system hibernation(S4)...Does anyone(Ex. Microsoft) define this max resume latency ?

The only thing I can think of that might have some sort of requirement is Microsoft's Logo requirements. Of course I don't know what these requirements are or if they do (or don't) include a "minimum boot time" requirement; and in any case they can't apply to an OS you're writing or apply to hardware that didn't jump through hoops to win a shiny sticker.
