>>>>>> I'm getting this error saving the >>>>>> configuration to flash memory.

Hi Luis
Maybe you get this error, because either there was an old .pon file on the harddisk or none at all. Imho the next power on of the KB will erase the savings in the flash?!

I would try to do the following:
- Delete (once again) the .pon file in the user folder (Master folder on)
- Copy to the user folder the default .pon file delivered with the Rel. 4.0
- reboot the KB and change a parameter e.g. in the utility menue, which you are shure about (manual) that it will be saved by "Power on Setup"
- Press "Save" and chose "Power on Setup". Be sure to press "Disk Save". I never us "Save" but always "Disk Save".
- Reboot again the SD1, I'm sure your parameter remains changed.
I didn't hear in the different forums of anybody having any problem with the power on savings.

Good luck
