  • Windows 8 ultra fast cold boot preview

    Engadget:

    http://www.viddler.com/explore/engadget/videos/3167/

    Rather than closing both the user session and the kernel session like in a traditional shutdown, Windows 8 will preserve the kernel session on the disk, thus creating a "hiberfile" that's much smaller than that of the usual Windows hibernation -- see the diagram after the break for a clearer idea. The result? An amazingly fast system bootup -- even with the battery removed to begin with -- that claims to be 30 to 70 percent faster than most systems tested by Microsoft.


    Looks promising. What was it, 3 secs? I could live with 3x that, no problem...Too bad my bios still will take longer. Why do we still need bios (the way it is now?)? We should be able to save the last hardware configuration and skip detection altogether, unless you press f1 or whatever. Initialize all saved hardware and pass on to the OS.

    More here:

    http://blogs.msdn.com/b/b8/archive/2...windows-8.aspx

    Our challenge then, was to design a way to meet all of these desires on today’s PCs without requiring some special new hardware. These were our goals:

    Effectively zero watt power draw when off
    A fresh session after boot
    Very fast times between pressing the power button and being able to use the PC.
    In Windows 7 we made many improvements to the boot path, including parallel initialization of device drivers, and trigger-start services, but it was clear we’d have to get even more creative (and less incremental) if we hoped to get boot performance anywhere close to fast enough to meet all of these needs.

    Our solution is a new fast startup mode which is a hybrid of traditional cold boot and resuming from hibernate.

    (...)

    The key thing to remember though is that in a traditional shutdown, we close all of the user sessions, and in the kernel session we close services and devices to prepare for a complete shutdown.

    Now here’s the key difference for Windows 8: as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it. Compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write to disk. If you’re not familiar with hibernation, we’re effectively saving the system state and memory contents to a file on disk (hiberfil.sys) and then reading that back in on resume and restoring contents back to memory. Using this technique with boot gives us a significant advantage for boot times, since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70% faster on most systems we’ve tested).

    (...)

    One thing you’ll notice in the video was how fast the POST handoff to Windows occurred. Systems that are built using Unified Extensible Firmware Interface (UEFI) are more likely to achieve very fast pre-boot times when compared to those with traditional BIOS. This isn’t because UEFI is inherently faster, but because UEFI writers starting from scratch are more able to optimize their implementation rather than building upon a BIOS implementation that may be many years old. The good news is that most system and motherboard manufacturers have begun to implement UEFI, so these kinds of fast startup times will be more prevalent for new systems.

      My next system will incorporate UEFI if the above plays out as expected and who knows, W8 might even serve as a FE. I can get over the heartaches that CF causes, that's for sure. Thanks Ripp, for the read. This is the first OS I would call truely innovative since 95. I like it!

        Yep, it looks very promising. Can't wait.

          it looks very promising, though i can only think of the last 'promising' os's microsoft offered right after a successful release(windows ME,vista?)..

              I just installed the ASRock E350M1, and UEFI rocks. It's literally one second and then off to the Windows startup screen. I'm really looking forward to installing Windows 8!

                I have the same exact board, and the only thing UEFI I saw was in the boot options when I chose to install off my disc drive. Didn't know what it was... Guess I have some research to do if it's that good...

                  UEFI is the replacement for BIOS.

                    Makes sense... Using a usb mouse in those sections, and it looks sleek too

                      Have you had any problems with your E350M1? When it boots, do you have any screen flickering, or any other problems? Mine's not behaving, so I think I might have to RMA this one back to newegg.

                        Got mine from newegg too... Yes, screen flickering while booting (horizontal wavy lines), but that's it. Normal login screens / desktop / apps don't have the screen flickering. I thought it was due to my powering of the monitor and having the 'noise' in it. I don't have the car until tomorrow morning, but I'll try to snap a picture of it happening if you would like to compare it.

                          That's what I have, too. I'm also having some hibernation BSODs, which I'm investigating now.

                            Looks like my Opus is causing the hibernation issues. It's shutting down before the hibernate (or shutdown) cycle completes. I hooked up a standard power supply and everything worked - hibernated, no post on resume, no crashes. With the Opus, it shut down before the CPU fan stopped, and on resume I see the post screen and then the resume screen, and then the crashes happen.

                            I'm sending it back to Opus to be checked out, and I'll get the firmware altered to add another 10 seconds or so before it switches off.

                              Hope that fixes it for ya. I have an M4 and have never had an issue with the hibernation!
