Hello,

I will appreciate any help on this... I have for testing purposes CentOS 4.7 running on VMWare workstation 6.5, I need to boot the centos virtual machine from the cdrom in order to test an upgrade to an upper centos version but I cant make the centos to mount the cdrom at the boot time, I got this message: mount: block device /dev/hdc is write-protected, mounting read-only ... after the boot i did check and the cdrom is not mounted.
I tried checking where the cdrom is linked to:

[root@server ~]# ll /dev/cdrom
lrwxrwxrwx  1 root root 3 Jan 13 00:42 /dev/cdrom -> hdc
[root@server ~]#

and tried mounting it manually and got the same message but i am able to access the cd content:

[root@server ~]# mount /dev/cdrom /media/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@server ~]# ls -la /media
total 487

[root@server ~]# more /etc/fstab
