The reason that ctrl-c exit is that you are running a script, when that script compleats the next step is to exit ipxe - you might want to test without having any embeded script - and press ctrl-b on boot and then type in those commands manually instead to see exactly where it fails and also having the ability to press ctrl-c without it exiting ipxe

I have an update . I did let client trying to boot and did go out in town to buys some groceries from the store .When I did come back ....15 min later to my surprize , client eventually booted in tinycore .That mean that the client eventually managed to download the iso file from the ftp server . So I did repeat the boot process in order to isolate the problem . So this is what happend .To download the tinycore ISo file it take arround 5 min . But that does not make any sense .And here is why . With all other FTP clients it takes around 20 seconds to download a 1 Gb iso file from ftp server . that mean that average read speed from ftp server is around 50 MB/sec . From the previous tests we know that ipxe actually use 50% of that speed (25 mb/sec ) while it seems to be frozen . The size of the tinycore iso file is only 24 MB . What happen is during those 5 min its downloading constantly from ftp server 25 mb of data every second . So in 5 min is actually downloading 300 seconds x 25 mb = 7500 Mb of data . The obvious questions here are :
1. Why ipxe need to download 7+ GB of data for a 24 mb iso file ???
2. Why the % counter indicating the progress of download in real time go from 0% to 100% almost instantly .....despite the fact that the iso file is not succesfully downloaded yet ?
