Hi Albert,
Sorry for the confusion. I did try several u-boots. None of them appeared to have any USB support as far as I could tell because u-boot didnt respond to any usb commands - e.g. usbinit
however I have been successful if restoring functionality to my netbook.
It appears the netbook was preloaded with WonderMedia Technologies U-Boot.
I attempted to contact WonderMedia to request the U-Boot again. They havent replied.
I then found a link to the WonderMedia U-Boot source. The source appeared to include a compiled u-boot, I tried it, it was very basic. It didnt even have LCD support.
I then did a lot of digging around the internet, I downloaded about 700 megs of operating system files from similar netbooks and I found a WMT U-Boot which works.
The working version is:
U-Boot 1.1.4 (Oct 8 2010 - 10:39:28) WonderMedia Technologies, Inc. WMT U-Boot Version : 0.12.01.00.27
So I'm pretty happy right now because U-Boot can finally access the internal storage.
The only downside to using the internal usb storage is the usb subsystem in u-boot appears to be quite slow. The command usbinit must be called first which appears to load the driver, and then scan the bus for devices. Once it is done the system can then boot from the usb storage. It easily adds atleast 5 seconds to the bootup, especially if the logo is loaded from usb.
The next step is to load an operating system onto the internal storage.
Thanks for your help.

Hi Albert,
I dont know of any u-boot board configs that were used for this device. That was my original purpose for emailing this mailing list - hoping that someone may have experience with this netbook and may be able to point me in the right direction but at this point its not looking hopeful.
Understood. But you have said you attempted install of several u-boot binaries, none of which had USB mass storage support; however if they have some sort of USB support other than mass storage, then maybe they could be rebuilt from source with mass storage support added. Can you list the boards for which you tried some binaries?
Amicalement,
Albert.
