Re: special device /dev/cdrom does not exist -- plz help

It just means that the symbolic link to your CDROM device isn't there.

Find out which device node your CDROM is connected too (see /var/log/dmesg for details), and create the appropraite symbolic link (ln -sf /dev/ /dev/cdrom)

If you areu sing the 'ide-scsi' module(lsmod), and are using the appropraite boot-loader options, then it gets a little more complicated.

Re: special device /dev/cdrom does not exist -- plz help

find out the device of cdrom device:
# dmesg |grep -i cd
or
# dmesg |grep -i rom
for example,
linux:/dev # dmesg |grep -i rom
hda: CDU5211, ATAPI CD/DVD-ROM drive
hda: ATAPI 52X CD-ROM drive, 120kB Cache
Uniform CD-ROM driver Revision: 3.12
cdrom: open failed.

then, you may make a sybolic like to the cdrom device file as follows:
# ln -s /dev/hda /dev/cdrom

If you have working CD and you know where is connect :)
you can use it:

linux IDE map:
Primary/Master = /dev/hda
Primary/Slave = /dev/hdb
Secondary/Master = /dev/hdc
Secondary/Slave = /dev/hdd

/dev/cdrom is just link

Re: special device /dev/cdrom does not exist -- plz help

hi,

/dev/cdrom is usually linked to /dev/hdc so let try mount /dev/hdc /mnt/cdrom, it should be ok.

After that create cdrom link to hdc or edit /etc/fstab and type right device file there:

/dev/hdc/ /mnt/cdrom
