Red Hat Bugzilla – Bug 7299
backpack cdrom not recognized.
Last modified: 2008-05-01 11:37:53 EDT
I know that this is probably not a bug, more likely my own ignorance, but
I cannot get Red Hat 6.0 to recognize my Backpack cdrom after the initial
install. The installation goes fine, parallel port cdrom recognized from
the boot.img disk, no problems, but when I try to mount the cdrom
(mount /dev/cdrom /mnt/cdrom) after the install, I get the msg: you must
So I type:
mount -t iso9660 /dev/cdrom /mnt/cdrom
and I get the msg: the cdrom does not exist.
Then, I go into /etc/fstab and change the line:
/dev/cdrom /mnt/cdrom iso9660 noauto, ro 0 0
/dev/bpcd /mnt/cdrom iso9660 noauto, ro 0 0
then at the command line I type:
mount /dev/bpcd /mnt/cdrom
and I get this msg:
you must specify file system
so I type:
mount -t /dev/bpcd /mnt/cdrom
and I get this msg:
the kernel does not recognize /dev/bpcd ad a block device(maybe 'insmod
Any help would be greatly appreciated, the Red Hat user list has not been
able to help me up to this point. I am concerned that I may have the same
situation with Red Hat 6.1 that I am waiting on a boot.img disk that
supports parallel port cdroms.
Remembering that the backpack plugs into the parallel port as a PARIDE unit, I
would suspect that you will need to enable and load the paride subsystem. If so,
try the following commands:
When you've done that, retry your mount command - it should now work.
I have tried the commands you gave me: modprobe paride
When I type in modprobe pf I get this message:
/lib/modules/2.2.5-15/misc/pf.0:init_module:device or resource busy
The error message looks like the IRQ (or parallel port) is already in use
by another device.
Check the BIOS settings for the parallel port.
I have checked my bios for interrupt conflicts, none exist. Com1 has irq 4 and
my parallel port irq is set to 7.
I presume adding
alias paride_protocol pf
doesn't fix the problem either?
You are correct, nothing seems to be working.
You can close this "bug". I have resolved my parallel port cdrom issue.
