Thanks for your reply but I tried the Esc key but it didn't work perhaps because I'm using an RF 2.4Ghz wireless keyboard which needs to be initialized. I don't have a USB keyboard to try. Also my RPis are not connected on a network by any way.dfeugey wrote:It does not hang: DHCP timeout is veeeryyyyyy long. A press on escape sould bypass it. Else, you have the solution to boot from the B to deactivate TCP/IP and then to boot again on the A+. Good luck.
