I tried to upgrade an image on a nm-cue as it seemed corrupted i followed the step from the cue bootloader and end result was unsuccessful so now when it boots this is what i get:

BIOS Version: SM 02.00
BIOS Build date: 09/17/02
System Now Booting ...


Booting from disk..., please wait.

Dont see any useful options when i type ? Idk.. running out of ideas.


Anyone has experience recovering from this. I can't find any documentation on it.

try ctrl break and stuff, ctrl c sometimes works to get to loader, but is the loader itself is spent you might be stuck. look here you might get lucky...
