    Yikes! I don't know... I set up one fog server. We also have a DHCP server that serves our network... any use?? Sorry i'm a bit of a newbie to this

    Do you mean you are getting an error when imaging a second PC (and a first one is fine) or do you get an error while trying to image two PCs at once?

    Two PC's at once...but they seem to be doing it now...I'm attempting 4 at once and they seem to be doing it. How odd. Do you think it could cause image problems?

    One has finished, booted up to Windows and all seems well...

    How weird...

    Probably a switch problem if they are all the same model. I occasionally get a glitchy transfer but it's usally about 1 out of every 150 or so imaging tasks that needs to be redone. If they are different models of PC and you get the issue again then you could try a different kernel and see what happens. Also watch out for recovery partitions on PCs which normally need to be removed before imaging will work properly.

    I have a similar problem in that I cannot see any options in the Kernel Update page in the FOG management.

    I am not behind a proxy and using a virtual machine with bridged access to the network/internet so should not be an issue. Is there a reason or where can I look to get the kernels to show without manually downloading them and renaming them?

    Is this where you get them all from... FOG - A Free Cloning Solution - Browse /Kernels at SourceForge.net

    and how do you check what the current Kernel version you are using? I have not seen it anywhere yet..?

    Cheers

    You'll see the kernel used during the boot process on a client, unless you've made any per host exceptions for the kernel file then it will always be the default that was included with whatever version of FOG you are using.

    I think if you cannot use the interface to download extra ones then you have to resort to just putting them into the kernel folder. I've always replaced the included kernel with one from version 0.24 as most of our equipment is fairly old. If I have a problem then I make an exception to use the newer default one.

    When you set which kernel to use you do so relative to the root of the tftpboot folder, so the value you set is "fog/kernel/kernelname".

    Thanks for your reply morganw,

    I have installed FOG version 0.29 and I see that the kernel gets downloads after the PXE boot. I don't see anywhere it display the version that it is included with the 0.29 version. I shall keep an eye out again for any numbers popping up.

    I might try kernel version 0.24 as you suggest or another new version, I am currently having issues booting some new Netbooks (Samsung N145).

    They PXE boot just fine, when they have pulled down the bootstrap images/kernel then it gives me some errors of...

    found HQ with no IRQ check BIOS/PCI
    init 0000:00:1d.7 fail, -19

    a few times then...

    IP-Config: No network devices available.

    So from what I gather here, the network card isnt supported somewhere!

    Cheers

    Plus it also then goes onto say 'hard disk not found!'

    So not sure what to do there also! Possibly change some kernel arguments I read somewhere if you could spare a moment of knowledge there?

    It shows the filename when it downloads it, so the default one is just called bzImage.
    It might be worth you getting some kernels that have KS in the filename, these are 'kitchen sink' kernels that are built to contain pretty much everything going.

    You could either rename bzImage to something else and then rename a KS kernel to bzImage, or set the host at the kernel level. If you do the latter you'll see the filename displayed as the kernel is downloaded (when the dots are running across the screen).

    Hi, did you figure out how to image the samsung netbooks? I've got 32 to do, and they are not liking fog. They do pxe boot, but then it seems like the netbook doesn't communicate fully with the fog server, despite downloading the pxe boot image.
    Thanks for your help!

    What stage does it get to and how does it fail?

    Side note - if the web interface takes ages to display the about screen ("i" button, displays the version at the top), it's probably because it needs a proxy setting. This also enables kernel downloads, the kernel update screen is blank otherwise.

    I don't think your network card is supported by the kernel so there is no connectivity after once the TFTP transfer has finished. Do you know which chipset these netbooks use?
    It also looks like you are using an old version of FOG as the latest ones have an option on the PXE menu called 'Client Information' where you can run a test to check it is okay with the disk controller and network adapter. The next version of FOG is apparently out today / tomorrow so it might be worth running the upgrade. If you don't want to upgrade the entire system then try using an alternate kernel (try one with KS in the name as they support a broader range of hardware), or get the kernel from the latest version of FOG and just drop that in.

    Yes I did fix this problem!

    I downloaded a different (newer) kernel and used that, worked a charm. Don't remember it being a kitchensink version.

    Good luck
