Well, to be honest, searching for tftp was not very fruitful. Hours of searches on the net brought me a little further, but a slightly more detailed help would have been great.
First of all, I could not find a hint on how to boot this bl**dy machine into tftp mode but it seems that pressing the "func" button after the red "i" starts flashing does something.
I found a tftp server with a uimage.bufallo but when the linkstation goes into what I think might be EM mode, I get the message
Client 192.168.11.150:somevaryingport C:\Users....\uImage.buffalo timeout
"somevaryingport" is varying.
This also happens when I switch of the windows firewall (windows vista ultimate) . I've got no anti virus software.
Any idea would be appreciated.
