    A few days ago I had to upgrade serveral Wyse’s with a newer BIOS.

    While I was doing this, I was wondering if it was possible to change the bootscreen of the Wyse. I started to work some things out and with a litlle help of the almighty internet I succeeded.

    So I created a small tutorial and a rar file with all the tools u need within it.
    I hope the manual is clear enough, English isn’t my native language.

    The file can be found here: http://www.dotbox.nl/extern/bioschange.rar

    Hi Rob,

    This is really outstanding work, I have not tested this yet but your document is really easy to follow. If its OK I will post this up!

    For others trying this remember that once you create your BIOS and pull the image with WDM or WSI the BIOS should be captured and you can push the .i2d file out to all your other terminals.

    Once again kudos to you for making and taking the time to share this tool!!!

    😀

    Just test and it works great! I used the tool from Phoenix (Awfl865.EXE) to flash the Award BIOS.

    Thanks again!

    After some surfing of the Wyse.com web site I see the V10L has a copy of the VL BIOS and the awfl865.exe.

    Wyse V10L download page:
    http://www.wyse.com/serviceandsupport/support/dlOraFW.asp?which=81&model=Wyse%20V10L

    (You are after BiosV10L1.10.zip)

    This may work for all VL Class terminals if you want to play with the splash screen on these.

    Also someone PM’ed me and asked about support and of course there is no way Wyse would support playing with their BIOS, so if it works go for it but roll back to the standard BIOS if it causes any issues.

    Still, a fun tweak!

    Of course you may post it up 🙂
    I’m glad to hear that the document is easy to follow, hope I didn’t make to much spelling or grammar mistakes 🙂

    You can flash the BIOS with every tool you like, as long as it is approperiate for your BIOS. I mentioned the uniflash tool, cause it works on a lot of BIOS versions and it helped me out to flash the bios with our imaging system. Maybe I’ll post something more about that later.

    How did you get the usb key to boot…. I have been messing with this for the past 2 hours and I can’t get a usb key to boot on the v90 to extract the bios file

    Simple answer I didn’t, I (mis)used our unattended installation.

    But there are several possibilities to boot into a dos mode
    – Find the right USB stick, Wyse cliënts (especially the 941GXL) don’t boot from all the USB sticks.
    – My favourite if you have an USB floppydrive, use this, I never had problems with this one, even with the older models.
    – Build a simpel boot image and boot the Wyse by PXE.

    Maybe there are more, but the above ideas should all work.

    Yes I can, I already have written a Dutch manual, but I’ll make a English one for this site.
    I think it can be very interesting, imaging as we set it up, takes about 2minutes.

    Very short, but gives you already an idea about how it works.
    1. Create a bootable network floppy and script it, so it makes drive mappings and detects the system type which it is running on. After this it’s should start Ghost with the right parameters.
    2. Convert this floppy to an image and boot it up with PXE.

    So it is not really an installation, but it is very, very fast. I’ll create a document which is a lot more detailed then the description above.

    As promised a small explanation how we image our Wyse thinclients.
    Due the lack of time, it is just a small explanation, but if you still have questions or problems,
    don’t hestitate to post to this forum or contact me.
    In the future I hope to write a detailed tutorial.

    This method is completlye different than the method of Wyse WDM/Rapport.
    We are very happy with it, but I’m not going to say this method is better.
    I think you have to try for yourself which you like most.

    It takes us about 2minutes to image an Wyse thinclient even if we image 10 or more at once.
    Litlle sidenote, we don’t use Rapport/WDM at all.

    How does it work.
    The idea is very simple, we create a server, very simple one, which runs a DHCP service(for example TFTP included in the package) and contains the images.
    We place this server in its own network, watch out, separate from other networks(otherwise the DHCP serivce can cause some problems!)

    Now connect a thinclient to this network and start it up, the client will receive a PXE package, this
    PXE package will load an imagefile (kind of bootfloppy) to the memory.
    Cause this image contains a editted Windows bootfloppy it will start-up and load some networkdrivers (V90, V90L and the J400 have all the same network card), it also gets its own computername (see autoexec.bat) with a simple program in we made in QBasic in combination with an reg file. Cause the different computernames we are able to image more clients at once.

    After this there is created a networkmapping and with a program called pciscan, this program looks for differences in the hardware so it knows which image it has to place on the client.
    It will start a BIOS update or Ghost.
    After all the work is done, it powersoff the machine.

    What you (probably) need to change
    The boot image is called boot.imz you can open it with winimage, it contains autoexec.bat which contains
    all the commands that are executed at the boot.
    Further you need to copy pciscan, wyse.map, poweroff.exe, test1.bat and eventually if you want to flash the BIOS you need to copy Uniflash.exe to the networkshare. You also need to copy Ghost.exe to this share, but since ghost isn’t freeware I haven’t included it in the package.

    Don’t forget to add pxelinux.0 to the PXE startup service in the DHCP service.

    The most important thing you need to edit is autoexec.bat, cause it contains all the information about the start-up and imaging process as we do it even the Dutch commentaries are there.
    Another thing you maybe want to edit is wyse.map it is combined with pciscan.exe to recognize the type of cliënt.

    If those two files are editted correctly then everything should work like a charm.

    We use the this method for almost 2years now and is incredibly fast (about 2minutes een with 10clients at once)

    If everything seems to work fine, it isn’t necessary to plugin the mouse, keyboard and monitor everytime.

    Still got questions or problems don’t hestitate to contact me.

    The package:

    @thinkthin
    , it is very basic and short explanation, but feel free to add it to your site.

    I would love to be able to do this, unfotunately your universal flash link does not seem to be good any longer. Also I am using V10L’s with WTOS and not linux, is this possible on that platform?

    We just started using thin clients so I have almost no experience, I did build a WDM system but have no idea what I am doing – any help is much appreciated!

    Thanks,
    Adam

    It seems you can find the exact same version at this link: http://www.softpedia.com/get/Others/Miscellaneous/UniFlash.shtml

    If you still got problems downloading, please let me know, so I can mail you the binairy I use.

    Unfortunately I’ve no experience with WDM, cause I’ve written our own management tool/imager.

    Don’t hestitate to ask other question.
