I suspect that to be the problem also, this morning i tried once more and it worked without changing anything, but at 50% it crashed again : Error – 300 processing Command "load h8000 bin" press any key to continue, so that was that.The first owner, who bought it new, told me he never could get it to work with the Viking CF, he always did the upgrades with a Keyspan USB to serial cable, that worked fast and perfect. I was thinking to buy one also but than i ran into the message that it's not possible to upload the 5.3 OS with the serial port………so my questions are you very very sure it won't work with the Keyspan USB to serial cable, what brand/type/size CF card would you recommend for the H8000FW ? thanks for helping me out, John
