    That is pretty quick.

    Does anyone have experience with the Commel pent M boards? The ones with the 915 chipset look attractive esp. with the "hd audio"?

    Ram Disk

    Has anyone tried using a RAM disk as the primary bootable disk? That "SHOULD" reduce both the boot times as well as the resume from hibernation time...A 4GB RAM drive should be acceptable.

    I've seen a 4GB flash drive for about $130 and an IDE adapter for about $20. I wonder if it would be faster than a 7200 HDD?

    RAM not FLASH

    Most flash drives are actually slower in execution that Hard Drives, I meant an actual 4GB of RAM (maybe 2 sticks of 2GB), somewhere in the range of PC3200 or so for speed.

    How can you use 2 sticks of DDR Ram as a drive? Don't you have to have it powered the whole time for it to keep the data? I don't understand.

    Flash drive can be used as a true drive.

    RAM Drive

    What you would do in all likelihood, is to max the RAM in your system and allocate a percentage of that as your RAM drive. During bootup, an image of the File system on the RAM drive is loaded to the drive, and the boot process continues using files located on this drive. During shutdown an image is taken of the RAM drive and stored onto local hard disk in prep of the next boot. I have used a product by http://www.superspeed.com/desktop/ramdisk.php Superspeed before for various purposes, and would recommend the RamDisk Plus version. It supports up to a 4GB Drive (16Gb if you run a 64 bit version of Windows), but obviously you will have to have some reserved for the system itself. I guess when I get to installing the PC into my car, I will try it out

    But if the image has to be stored and read off the HDD, how can it make the PC boot faster?

    It seems what your talking about is to help the PC run faster.

    Access times

    It is the access times of the media...Dumping the contents of the image to your ram Disk takes moments, for example sakes let us say it takes 4 secs...Once it is on the RAM disk, the difference is in the range of an order of MAGNITUDE better for solid state vs. spinning magentic media. My gaming box at home can go from a cold boot to fully running (this means all apps and processes have started and are running) within 30 secs easily...And when I resume from hibernation, it is about 2-4 secs before it is ready to be used. Most OS disk access is done to the RAM disk rather than Hard drive (i.e calling .dll's, system files, etc..) which is significantly faster. The gist of this is, RAM is orders of magnitude faster than a HDD, leveraging this speed by placing oft used system and application files on this disk can be very helpful You see some example benchmarks here:

    I still think your missing the point of this thread which is to boot up faster from hibernation.
