info-File and Floppy Drive

Hi, I have a problem with a 7.3 automatic installation. The installation boots from a CD and if there is no floppy-drive connected, the installation will halt in the "Searching for infofile" section. I think, that Yast searches for the info-file on the floppy (first?), but it will find nothing and so it crashes. What's the meaning of the readinfo entry in syslinux.cfg (the value here is 2)? Thanks, Bernhard
