Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

This most likely means that there is a syntax error in the fstab file. The most obvious error to me is a missing comma in between codepage=850 and ro. Apart from that try trimming the number of options (for example iocharset defaults to iso8859-1). Also try setting the filesystem type. For the floppy drive vfat is probably best and for the CD-ROM/DVD-ROM drives iso9660 is probably the best bet. This replaces the auto in the third column.
It is interesting that it says /dev/fd0 is invalid. Can you copy a disk image to the floppy (e.g. with "dd if=disk.img of=/dev/fd0"). If this fails then it would seem that there is a problem with your device files rather than the fstab file for the floppy drive and possibly for the cdrom/dvd-rom drives as well.
I don't know I most likely think it's a fstab error cause before I compile a new 2.6.6 kernel it was working fine with all defaults options but I tried putting them back in and they don't work at all... I can't access the floppy at all even though when I try to mount it or mount cd-roms you see lights flashing...
Please explain what you mean by removing "unmask and codepage" for all us n00bs. I have been getting the exact same problem. I thought it had to do with supermount. So I got a patch for it, and it still doesn't work. Please help me out here. Thanks.
Here is my old /etc/fstab file :
fstab :/dev/hdc /mnt/cdrom auto umask=0,user,iocharset=iso8859-1,codepage=850,ro,exec 0 0
/dev/hdd /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-1,codepage=850ro 0 0
/dev/fd0 /mnt/floppy auto umask=0,user,iocharset=iso8859-1,sync,codepage=850 0 0
Here is my new one :
/dev/hdc /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro,exec 0 0
/dev/hdd /mnt/cdrom2 udf,iso9660 noauto,owner,kudzu,ro,exec 0 0
/dev/fd0 /mnt/floppy vfat noauto,owner,ro,exec 0 0
I removed some useless stuff and modified other but I think only removing codepage=850 and umask=0 should do the trick. Oh and don't forget to put the auto to udf,iso9660.
