    It dumps the ENTIRE size of your memory into a hibernate file. IF you reduce the vailable memory to windows (Add /maxmem=xxx in boot.ini or something like that) then windows only sees xxx of the total physical memory you have physically installed in your system, and your hibernte file is only xxx MB in size. That will help reduce boot times slightly. PS> xxx must be <= total physical memory. You cant pretend you have more memory than you really do .

However, with hibernation resume, the boot portion is simply a file dump into memory. It just takes the image it had created and slaps it onto your memory. There's no real bootup and nothing really to tweak other than decreasing the amount of RAM you have.


    For example, I have 512MB of RAM and have been thinking about decreasing that to 256MB to get to music faster. With a stopwatch, this is my startup time:

    1) Key turn to MB power on: 2 sec
    2) BIOS to OS handoff: 15 sec
    3) Resume from hibernate: 10 sec (<-- the time that bootvis reports)
    total: 27 sec

    If I decrease to 256MB, the only part that is affected is (3) resuming from hibernate. Cutting the memory in half approximately decreases that time in half, down to 5 seconds. My total startup time then would be 22 seconds.



    Nerd2: No, it dumps everything. If you use hibernation, look for the file c:\hiberfil.sys. That file is the same size as your memory. Everything that's in memory is placed in the file. If you have 512MB of memory, you'll have a 512MB hiberfil.sys file.
    But is that 5 seconds worth the loss in system performance due to less memory? My experience has been that XP does not perform as well with anything less that 512 MB of memory. My carPC has enough issues with CPU loading as it is and I know system performance would get even worse with less memory.

    No, old is when you can remember those days when you wished for a memory upgrade from 16K to 64K. Well actually getting to 48K would have been nice.



    Subscribed by the way.

    I can't debate the decrease in system performance because what is an acceptable decrease is different from person to person. I personally ran fine with 256MB and saw no appreciable difficulty *for my applications and expectations* but obviously I can't make that blanket claim for others since everybody has their own demands on their systems. Like pretty much everything in the carpc world, it's a compromise. Maybe 384MB is the sweet spot for your uses, I dunno. I've ran XP (stripped down, of course) fine on 128MB; it's mostly the applications that have the most rigorous demands on memory.

    I'm getting 11 seconds from turn key to music playing

    1gb ram, via epia 15000 and 7200rpm sata harddisk
    XP Home edition full install with a bunch of services disabled...
    No maxmem. no minlogon

    bootup is 17 with some tweaks.

    I recommend a search for TUNEXP to defrag bootfiles

    swordfishunter> Interesting.
    I have a bios which is ready in 5.5 seconds. But My HDD takes 9 seconds to spinup and be detected. Therefore my bios initialisation takes 9 seconds all up before it gets the Loading/Resume Xp screen. My HDD is a 300Gb 7200RPM Western Digital Caviar IDE. I have had a 14 second 'Key turn to playing music' scenario when using resume. If I had a faster HDD I could save 4 seconds. I wont use a 5400RPM drive though, as it will take longer to load XP/resume data, even though it will initialise faster. This longer loading time actually creates a greater delay than the time benefit it gives by faster initialisation.

    This would improve my resume from hibernation time a bit probably, but only by a few seconds I bet. I have a 5400 2.5" HD and it boots fairly fast, haven't timed it in a while though...

    I found that my Seagate 300G SATA drive spins-up in about 7-7.5 seconds (which is 2-1.5 seconds sooner than my IDE drive). I dont think there was much difference in the Loading/Resuming XP data transfer time however.

    Different drives have different bioses, and even these subtle differences can make a big impact on startup time. Finding the right one is the trick, and it could mean testing many different drives.

    If you add the /maxmen=xxx into the boot.ini file, doesnt that stop windows from using the extra memory altogether? If so you may aswell remove the actual module... . (Unless you only have 1 stick of 512mb and want to reduce to 256mb)

    I few things i have found that reduce boot time are...

    ---------------------------------------------------------------------
    Edit your MSdos.sys file with notepad and add the following 2 lines in the [OPTIONS] section.
    DrvSpace=0
    DblSpace=0
    (This will stop windows loading the drivers needed for HDD compression. No longer used with modern HDD's)
    ---------------------------------------------------------------------
    On XP, goto Start -> Run, then type 'Msconfig', check all the programs in the startup area are actually required.
    ---------------------------------------------------------------------
    You can increas your windows delay time by removing most of your fonts (Windows caches these fonts on boot). It may not save you alot of time, but it all adds up. The best way to sort out the minimum you need for windows to run is to create another folder on your hard drive. Move all your fonts to this folder. Windows will have a funny 5 mins, then copy the minimum back into the default fonts folder.
    ---------------------------------------------------------------------
    While you Caputer is in your car, 99% of you will not be on a network. Disable it, as it takes ages to check all your networks etc...

    Right click on ‘my computer’ and select ‘manage.’

    Expand ’services and applications’ and select ’services’ to open the services window.

    Highlight the ‘workstation’ service, right click and select ‘properties.’ Set the ’startup type’ dropdown box to ‘disabled.’ Click ‘ok.’

    (Note that you will need to re-enable the workstation service should you wish to network your PC in the future)
    ---------------------------------------------------------------------

    Something i have toyed with, but not actually tested is using booting from a USB memory device. HDD transfer rate is 100mb/s, where USB is 480mb/s.
