Unfortunately the install script netbsd 8.0 stop with
root: unknown
boot:
The install program start normally/ correctly at the beginning, on/from the CDROM, which so is recognise by the bios ....
and with surprise after analyse device etc , STOP to recognise the media at the critic time to begin the INSTALL SCRIPT by itself
The only possibility is
reboot dbb reo halt etc
No cd9660 mentioned ....
No more connection with CD ROM ....
Perhaps there is some command to write to reconnect the CDROM .... and go on ....
