From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)

Description of problem:
CDROM is not mountable after the install and reboot process is completed. 
All other devices are mountable.

This CDROM drive is detected and mountable with Red Hat 7.1

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. CDROM used to boot and install Red Hat 7.2
2. Reboot
3. mount /dev/cdrom /mnt/cdrom

Actual Results:  This error message is returned to the console
  mount: /dev/cdrom is not a valid block device

Expected Results:  This message should be returned to the console and the 
CDROM is then mounted and usable:
    mount: block device /dev/cdrom is write-protected, mounting read-only

Additional info:

This is from the symbolic link in the /dev directory
lrwxrwxrwx  1  root  root    8 Oct 14 22:09 cdrom -> /dev/hdd

The /etc/fstab file contains this line
/dev/cdrom   /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0

This information is from the boot process
    ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:pio
    ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
hda: WDC AC33200L, ATA DISK drive

/dev/cdrom apparently isn't created correctly in your setup, reassigning.
Comment 2 Jeremy Katz 2001-11-30 16:32:23 EST
Run depmod post-install... a run of it during the installer didn't catch the
different symbols.  (also, upgrade to the errata kernel as installing it will
make this be magically fixed as a side effect :)

This is fixed in CVS

Thankyou very much, depmod has fixed the problem and now the cdrom is usable.

Two final questions;
What is  the errata kernel? -- also, upgrade to the errata kernel as installing 
it will make this be magically fixed as a side effect 

And what is CVS?

Thank you.
