That is one solution that works without understanding why ..

This is what I wrote:

Now to explain why the other solution works ...

The "first" Ctrl-B is before autoboot have run, which means before ifopen/dhcp. If autoboot fails to find information for booting, such as tftp server and filename, then it will present you with the "second" Ctrl-B. And in that case ifopen has already run.

So to summarize:
* Enter shell and run ifopen for it to work in both cases (it still requires the presence of a NIC)
* If you have a DHCP server that gives out boot information there will not be a second Ctrl-B
