Description jmannion 1999-11-24 17:53:03 UTC
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
specify filesystem.

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.

Thank You,

John Mannion

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:

    modprobe paride
    modprobe pf

When you've done that, retry your mount command - it should now work.

Comment 2 jmannion 1999-11-24 23:02:59 UTC
I have tried the commands you gave me: modprobe paride
                                       modprobe pf

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

Comment 3 Bernhard Rosenkraenzer 1999-11-28 13:24:59 UTC
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.

Comment 4 jmannion 1999-11-30 14:43:59 UTC
I have checked my bios for interrupt conflicts, none exist. Com1 has irq 4 and
my parallel port irq is set to 7.

Comment 5 Bernhard Rosenkraenzer 1999-11-30 16:11:59 UTC
I presume adding
	alias paride_protocol pf
to /etc/conf.modules
doesn't fix the problem either?

Comment 6 jmannion 1999-12-01 20:35:59 UTC
You are correct, nothing seems to be working.

You can close this "bug". I have resolved my parallel port cdrom issue.

Thank You
