I'm running Mandrake 9.1 for the last several months with no problems, till today. For some reason my /dev/cdrom & /dev/floopy no longer exist. I did install win4lin 5.0 do you think that the new kernel might be broken? Any suggestions or advice will be appreciated. Im stil a newbie.

There is a kernel option called devfs that could be afftected (I have it turned on) ... but there may be an easy fix.

Do the command:

less /etc/fstab

(use the arrow keys to scroll and q to exit when finished)

You should see what devices you are trying to mount ... mine says this:

/dev/fd0 /floppy auto user,noauto 0 0
/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0


So I need to checkout /dev/fd0 and /dev/cdrom....let's start with the cdrom0.

do the commands:

cd /dev
ls -al | grep cdrom


My result for cdrom looks like this (I removed several other items, those listed are the relavant items only):

lrwxrwxrwx 1 root root 11 2003-11-14 12:43 cdrom -> /dev/cdrom0
lrwxrwxrwx 1 root root 9 2003-11-14 12:43 cdrom0 -> /dev/scd0
brw-rw---- 1 root cdrom 11, 0 2002-03-14 15:54 scd0


Now, if you have a cdrom0 and not a cdrom, it is simple to fix...do this command as root from within the /dev directory:

ln -s cdrom0 cdrom

(I have scsi cdrom emulation turned on becase my cdrom is actually a dvd-rom player ... but the link from cdrom to cdrom0 is the same ... i just have a link from cdrom0 to scd0 as well, you may or may not have that).
---------------------------
My floppy is /dev/fd0 ... and the command:

ls -al | grep fd0 looks like this:

brw-rw---- 1 root floppy 2, 0 2002-03-14 15:56 fd0
