[wplug] Not recognizing CDROM

[Weber, Larry A]

I just tried to upgrade my Red Hat installation from Version 7.1 to 7.2.  I
know of several people who have done this successfully, but not me.  The
upgrade changed the file systems from ext2 to ext3 and then later crashed.
I exited the installation but the file systems were not restored and I could
not reboot 7.1.

So I did a clean installation of 7.2 from CD.  After completing the
installation and rebooting, I find I cannot mount my CDROM (the same one
that I used for the installation).  The error message tells me that the
CDROM is not a valid block device.  What does this mean and how is it fixed?

This installation will be used for cross platform embedded system
development and will not be connected to a network.  Are there applicaitons
that can be shutdown (like sendmail) that will improve system performance?
If so how is this done?
