reset, of course. Just a typo ;-)

Just played around with my usb stick and reduced the size of the first 
partition. When I now try the usbboot command the number of blocks is 
exact the size of the partition.
Is there a special way of creating the image or can I use the same I use 
with the tftp command?

I tried to follow DULG -booting from IDE, Compact Flash. Maybe it was 
not a good idea...
Copied it from my host to the stick. This is not the proper way?

Can you tell me which fs to use? I tried it with dos.

Mit freundlichem Gruß,
