    hi

    i’ve just managed /i couldn’t find anything about that over internet, so i’m thinking that i’m the first πŸ˜‰ / how to connect a sata hard drive directly to wyse v90l terminal.

    i know, that in most cases such a thing may be useless, but I need to use my terminal as a web server, so disk speed and reliability is crucial.

    first of all – I’ve found two places signed “sata1” and “sata2” on a mainboard, next to bios battery. i’ve also found, that all solder pads are directly connected to the southbridge which -acoording to technical specification – has a sata controller, even capable to use it as a raid matrix.

    So, i’ve cut a sata wire in a half and solder it to the solder pads.

    after check, that it was soldered properly /without any brake or short/, I’ve found a source of 5V on a mainboard, and solder there a power connector. It’s important, that i use 2,5 inch hard drive because it need only 5V /not 5 and 12 as a 3.5 inch drive/. after that i realize, that… things didn’t work as i’ve expected πŸ˜• – sata controller wasn’t enabled in a bios, and there wasn’t such an option it it..

    i did some research, and planned to flash some other bios from similar VIA epia board, but it was a little bit πŸ˜‰ risky, so I’ve try to check, if an original bios rom has sata support. I’ve use Modbin to check it and success!! there was a possibility to enable sata option – and so i did.

    after that bios has detected correctly my hard drive, there is also possibility to boot from it.

    if anybody has any question – i’ll try to answer

    and… of course i don’t take any responsibility for any damages done.. blah blah

    Wow, that’s pretty impressing.
    Can you give us some more details on the BIOS part and usage of Modbin?

    hi again

    1. – download complete flash-rom with windows XPe from WYSE website /i think, that it’s also similar for terminals with linux or other OS’es/

    2. download WYSE usb firmware tool from wyse website

    3. run wyse usb firmware tool
    -on first screen click “next”
    -leave first option selected and click next
    -select your OS /i’ve leave first option selected- i don’t have an idea does it matter at all what you select here ;)/
    – select update firmware
    – select only BIOS option
    – click next
    – browse to a directory where update files are extracted
    – select *.rsp or *.i2d file /don’t matter which of them/
    – click next
    – if your usb drive is connected, you’ll see it in a field on the screen, if so, click next πŸ˜‰
    conversion in progress blah blah blah….

    in meantime, download newest version of modbin – i used modbin62.04.03.exe

    copy modbin to a working directory

    when wyse usb imaging tool finishes click finish.

    detach, and reattach your pendrive

    – browse your pendrive to “image” directory
    – You’ll see “nor.img” file <– this is bios image
    copy it to your working directory /same directory as modbin executable/
    – rename “nor.img” to “nor.bin”
    – run modbin
    – select “nor.bin” – open it

    ok, so here we are

    – navigate to “edit setup screen”

    -click enter

    now you’ll see a tree – view structure of bios setup screen

    navigate – right arrow – to standard cmos features… πŸ˜‰ now go down with arrow /you can see other bios options disabled in our bios…. i don’t know if they are working too if enabled/ to integrated periphials, under this menu you’ll see “OnChip SATA” – select it -and enter as you can see this item is selected as “disabled”, navigate to “normal” and select it with a spacebar, when done, click escape to exit to previous menu, navigate one item down to “SATA Mode” and do the same as with On chip sata /select as normal/

    when done, exit to main menu, select “File”, enter, Save bios.

    now change file name to nor.img, copy the file to “image” directory on pendrive – replace the original file with modified.

    when done, flash it normally by booting wyse terminal from usb.

    if the process is successful you’re done, now You have your sata enabled πŸ˜‰

    thanks πŸ™‚

    PS. remember, that dealing with bios is always risky, be sure to double check everything at any stage of flashing – in this case – don’t mess with any other options in bios settings because it may brick your terminal if “enabled” function isn’t supported by hardware. /eg. – there’s “hyper threading ” option in a bios – i don’t think, that via c7-m can handle this ;)/

    also, check if edited bios file is same size as before editing, and remember to unmount pendrive before detach it from your PC.

    If you have a second unit you can minimize the risk of a brick.
    I case one of the unit is bricked due to a wrong or defect BIOS, you can open both unit, unplug the BIOS chip in both unit, plug in the working one in the broken unit, start USB imager and before confirming the flash process swap the BIOS chips again.
    Sounds risky as the unit is still running but I did this several times and it worked always.
    This way you are booting the unit from a working BIOS and then reflash the broken BIOS via USB Imager.

    ha ha.. “hot swapping” – I did it before with PC’s but i haven’t got second terminal and haven’t got any spare chip at home.
