You have to mount to existing mount points. In other words, if /mnt/cdrom doesn't exist and that's what you wanna use, you have to make a cdrom directory under /mnt. But you should already have a /cdrom directory under the root directory. And if your drives are scsi, try replacing /dev/fd0 with /dev/sda for the floppy and use scd0 and scd1 for your cd-roms.

The linux kernel config thing under KDE's control center doesn't work for anybody...so no worries.
