Hi,

I've a problem mounting a DVD.

Basically I'm upgrading from RedHat 7.2 to Fedora Core 5 and I've burned
the FC5 install DVD. I swapped the CD drive in my Linux PC for a DVD drive
(Pioneer 109) booted and typed 'mount /dev/hdc /mnt/dvd' no problems, it
worked fine and the files were all accessible in '/mnt/dvd'. So I tried
booting from the DVD... can't boot from DVD's with the system BIOS. Oops.
So then I tried booting from a Linux boot floppy disk - the kind to allow
you to use 'parted', 'mount', and not much more. This allowed me to mount
the DVD drive from /dev/hdc but then told me 'no medium is present' in the
drive --when the same DVD was in the drive. So I rebooted into RH 7.2 on
my hard disk, and now when I try to mount the drive using the same command
as before it now tells me again that 'no medium is present' in the drive,
when before it worked fine. Several DVDs (that I've verified work on
another PC) all get the 'no medium is present' message from 'mount'.

Please advise what the problem may be and how to resolve it.

Many thanks.

MS,


RH has no filesystem type compatible with DVD filesystem.

You need to make boot CD which image is put in the /image directory of
your FC5 install DVD.


Kind regards,

Did you verify your DVD was made correctly? DVD's are harder to get right,
and some writers are better than others.  From what I have heard, the
Pioneer drive should be very good.  I also thought that Plextor would be
very good, but it produces expensive coasters, in general. Memorex,
LiteOne work fine though, IME.

It's been a while since I was using RH7.2.  I am not sure it would handle
the extensions to iso9660 which allow optical to go beyond 650M.  Your
DVD disc could be fine, but it if the OS lacks the UDF extensions to
iso9660, then it could report "no media found," as a general error
message. If you could actually boot from the DVD, those messages might
disappear inside the setup platform, and within your new install.

Yesterday, I discovered an interesting utility which makes it possible to
boot cds/dvds when BIOS support is lacking.  I read about the method here:
http://gentoo-wiki.com/TIP_Chainloa...D-ROM_from_GRUB

I was able to make a boot floppy image which encapsulates the method. Let
me know if you'd like me to post that image.

Thanks Jan. If RH has 'no filesystem type compatible with DVD filesystem'
how come I was (initially) able to mount the DVD and access the files on
it using RH 7.2 before things went wrong after trying to boot from it, etc.?
?

Thanks and regards,

Did perhaps RHL7.2 remove your /dev/dvd device???? It really is not needed
anyway try mounting using the cdrom mountpoint; mount /mnt/cdrom

The main problem is booting the DVD media, try this floppy instead;

With all the grief you're going through, wouldn't it be easier to do your
installation with FC5 CD's for now?

This sounds like it might be the isolinux problem and bios limitation on tha
t
machine. I used a tool called Smart Boot Manager myself, but I just saw this
suggested in another redhat group:
http://amdg.no-ip.org/slackware/sla...linux/sbootmgr/
My own 7.2 install CD will boot, but the FC5 and many others will not on my 
old
machine.

No the device is there. Mounting to /mnt/cdrom has the same effect as before
.

Already tried it and a no go. :-( Detailed already in my reply to Douglas.

Cheers.

Thanks Nico. I had assumed my booting-from-the-FC5-DVD problem was that I
couldn't boot from the DVD drive. Do you think the FC5 CDs will boot from
my DVD drive?

Cheers.

Thanks Bob. I tried SMB but it did not work, as detailed in my reply to
Douglas.

Cheers.
