SuSE 7.3 by ftp

Hi, I am trying to install SuSE 7.3 by ftp, everything seems to work fine until the package management stage, at that point I get this error: An error occured during the installation ! When I look at the logs by pressing alt-F3, I see these lines: starting yast1 inst-execute-yast: 921 command_ti = "/inst-img/sbin/inst_setup yast1" yast1 return code is 256 (errno = 2) sync... ok any suggestions on what to do?
