I have an external programmer and a full backup of my current bios. nothing writen, there was a label but it had to come off with time.
How can I concatenate images? The update is not a full bios, is it?

That's unfortunate. Do you have an external programmer (something like
a buspirate) that can be used in case things go wrong? Can you tell if
there is anything written to the lower half of the chip? It could be
as simple as concatenating the 256KB image to itself to create a 512KB
image. But I wouldn't recommend trying that unless you have a good
means of recovering.
