    After doing a swap with a working unit we have identified the 512MB flash unit to be faulty. The TC is out of warranty.

    We are looking at generic 44 pin IDE flash modules.

    Does anyone know if replacing the flash will work? (with a none WYSE upgade).

    If so, how do you flash a unit that has no OS on the flash? (I am guessing USB imager).

    The biggest “official” image is for the WYSE 1GB v90 model. Could I use this on a 2GB flash, and if so, will I have 2GB C: drive, or will it be limited to 1GB because of the image was designed for a 1Gb flash?

    Thanks.

    You should be able to use other flash device without an issue but this is nothing I could prove. I woul dsay the chance that it will work is around 80-90%.
    Using the original Wyse image will auto-expand the image to the available flash space.
    Do not use a flash larger than 2GB.

    USB Imager will work fine. Otherwise you can also use WDM.

    From Memory.com I have used the Transcend 1GB 44 pin flash module, they have other sizes. Cost for 1GB only $18.80. I have never tried a push, only a install and a clone.

    Thanks for your help on the modules.

    When you say “install and a clone”, do mean WDM?

    thanks

    Install = linux installs also with out flash but a 20gb 1.8 44 pin IDE drive anything that will or can install.

    Clone = exact full copy of another units flash put into 2nd unit.

    I (now) understand. 😀

    @no one in particular ……..
    We purchased a 1GB , 2Gb and 4Gb modules from here
    http://www.orcalogic.co.uk/asp/prodtype.asp?prodtype=47077&ft=d&st=1

    The 4Gb (TS4GDOM44V-S-B289) was the first to come, and we used in to replace the failed stock 512MB flash. The drive was detected in the BIOS as “transcend”

    The 1GB flash image 9V92_S673_1024 would not fit on our 1G USB drives so we had to use the smaller 9V92_S625_512 image . It is a pain that all our “branded” >1GB USB drives lock the wyse terminals and we cannot boot from them.

    When creating the wyse bootable USB drive we did not select “keep existing partition size….” from the options.

    The installation went ahead as normal, with a few ‘warning’ messages at the beginning about the flash disk.

    Upon completion and reboot, a script initiated that (through a dos box) showed the OS was expanding to fill the 4GB drive. Until than I was worried I would just have a 512MB on C: due to it being a 512MB image.

    However I have only tested it for about 5 minutes, perhaps other problems are awaiting discovery ….

    For completeness I should also explain that initially we did create a 1GB USB image that we later found was bad. When trying to install from it, we had a messages about an incorrect partition on the disk, which we assumed to be the usb install complaining about the 4GB flash (in reality it was the wyse box complaining about the USB drive). To ‘solve’ this we did a proper install of windows to create a 4GB partition, before retrying the USB installer. Of course it did not solve the problem, and it was only when we re-imaged the USB drive did we work out what the problem was. It was then we used the 512MB USB install
