Red Hat Bugzilla – Bug 242956
F7 CDROM installation method fails to recognize CD/DVD drive
Last modified: 2008-02-13 09:16:19 EST
Description of problem:
When installing F7 from the DVD, after you select the installation type as CDROM
the install then fails to recognize the CD/DVD drive and prompts for driver
Version-Release number of selected component (if applicable):
Always on certain machines.
Steps to Reproduce:
1. Put F7 installation DVD in DVD drive.
2. Boot from DVD drive.
3. At Installation Type screen select CDROM.
Install gets stuck because it cannot recognize CD/DVD drive.
Installation recognizes CD/DVD drive and completes F7 installation.
This has happened on two systems with Lite-On CD/DVD (Sony?) drives and also
when installing F7 in QEMU 0.8.2 on FC6 host.
I have the same problem with a Slimtype (Lite-on) DVD A DS8A1P but (to me) it
looks like an issue with the kernel released with Fedora 7.
Unofrtunately in the forum there are other people with Lite-on/Sony drives
experiencing the same problem:
Yeah, I can confirm this bug with a Pioneer DVR-111BK 16x16 DVD-RW.

Im seeing the same issue with a TS-H553 and a QSI SDW-085. Problem may exist
with the changing of device nodes for ATA drives from FC6 to F7?
I get the same error on a HP DL360G5 using a stardard IDE drive:
I had this problem on a motherboard with VIA chipsets and a celeron 850
processor (a MS-6723 board). The DVD-ROM drive was then the slave on a single
connector connected to the primary IDE channel. Putting the DVD-ROM as master on
the seconrady IDE channel fixed it.
Similar problem on ThinkPad T61. Prior to error, it hangs (times out?) for a
long time at "Loading SCSI driver - Loading ahci driver". It isn't clear to me
that it is having trouble finding the *source* of the install. It may be
getting past that, and looking for a suitable *destination*.
Trying an FC5 install on this T61, the actual error seems to be in locating a
hard drive. When asked to select an appropriate driver, it already has
"advanced ahci device" showing, and just selecting "done" allows installation to
proceed. (This may just be noise on my part.....)

Additional (probably useless) data point: FC6 32 bit (6.93) installs OK on this
T61 w/the usual tap-dance around anaconda bugs (don't select "extras").
The priority on this bug should be change to high because even if you install via network, post installation
the CD and DVD are not recognized. After booting, simply check dmesg output and you will see the drive
is not found. This makes Fedora 7 unusable on my machine because I can not create or restore from dvd
Kevin, I agree. Without a CD/DVD drive it's very difficult to restore any
backups. You could boot into rescue and enable networking and then load the
backups into another CD/DVD drive on another non-F7 machine but who has time for

Alan, there will ever be a re-spin of Fedora 7 with all these patches applied
(as it happened with F6) or should we wait for Fedora 8?
Reassigning to kernel on the basis of several comments on this report, which
makes it look like this is happening post-install as well.
I experienced the same problem when I installed FC6 on my computer. My
installation got as far as selecting the keyboard and then couldn't find a
driver for the drive it was installing from! I am using an ASUS DRW-1608P3S. A
colleague of mine eventually got it going, but I don't know exactly what he did.
I think he somehow told it that I was using a generic CDROM drive. Later I used
a F7 update disc to install Fedora 7, but this time had no problem so I figured
the problem had been solved. I agree with Kevin: the priority for this bug
should be changed to HIGH as it seems to be ongoing.
Patch that should fix most of these problems will be in the next F-7 kernel.
It just went into upstream 2.6.22-rc6
I had this problem using tdk DVD media, used a maxwell DVD with same .iso and
problem left. Cheap media is part of the problem.

I am having the same problem while installing Fedora 7 through a DVD on my
laptop (Dell Latitude D630).If I select CDROM as packages media it asks for

not take the path for the iso file.I tried giving the path as /images to

Also I couldnt find the DVD drivers for fedora.

It appears that most latest linux distributions can't recognize the DVD-Rom. I
have tried Gentoo 2007, Knoppix 5.1.1, Fedora 7, and worse yet, even Fedora 3

We have a lot of confirmations, including reports that the problem does not
appear in F8. Obviously someone knows how to fix it, so has it been taken up by
anyone as an action item? I would like to hear that someone is working on a fix
and whether there is some estimate of how long it will take. Otherwise we might
as well write off F7 as a failure and wait for F8, and put out an announcement
Problem is almost certainly fixed in the F7 kernel updates, but nobody has done

Ok, I had the same problem of the DVD not being recognized. Tried Fedora 7
then Fedora 8 test(7.91). Both were 64 bit versions. I finally got it to work
without a problem by removing 2 gig of ram from the system. If it helps, I have
the following configuration.
ASUS M2N SLI 4 Gig of Ram with AMD 5600
IDE drive 0 80 Gig WD (Fedora 7)
Sata 1 Seagate 250 Gig (Windows Vista Ultimate 64)
Sata 2 WD 200 Gig (Windows XP Pro)
Sata 3 Samsung DVD Writer
Sata 4 Pioneer DVD Writer
I had to add "mem=4096M" to get it to boot into graphical mode after the
install, and the 2 gig was added back.
I am working with Dell Inspiron 530s, and am experiencing the same issues.
I have tried F7, F8T1, F8T2, and a pre-release of the Unity Project's F7 respin.
None of them have worked except F8T1, which worked for a little while until an
update killed that too.
Booting with the SATA controller in IDE mode results in the installer trying to
load the ata_piix driver for a while, giving up, and then asking me where the
installation media is.
Booting with the SATA controller in RAID mode simply results in a kernel panic.
Booting with the acpi=off kernel parameter has no affect.
Fedora 8 test3, test2 and test1 seem to work on my Acer 5920 with Slimtype DVD A

Did you try adding "pci=nomsi,nommconf" to the kernel options?
"libata.pata_dma=1" works with Pioneer DVR-111D.
Removing from blocker list since we have the pata_dma option.

This option has been changed to 'libata.dma' for Fedora 8 final, since that is

For me this bug is still in F8 -- at least the same symptoms as in F7, described
in this bug, are present.
My system has a Pioneer DVR 111D with an Asus A8N-SLI Premium motherboard and
Athlon64 X2 cpu.
As with F7 I've been able to install F8 using the network (and using a fix
published here for a very disturbing anaconda bug) but this option is not
universally available and I consider the continued presence of this bug to be a

fact it has xen after the F8 upgrade is not relevant. Although the xen kernel
was present before the upgrade it was not the running xen in F7.

I have this problem in Fedora 8, it will not let me install with the DVD. I
installed by pointing it at the ISO on my hard drive, however, now I cannot use
my DVD drive on the installed system. Any pointers on how I can make this work
would be welcome.
Booting the installed system or install disc with pci=nomsi,nommconf or
libata.pata_dma=1 did not help. I'll upload the output of the three commands.
(This is odd because I have not had any problems with distros like Fedora 7 or
Ubuntu 7.10 in the past.)

I actually just solved my problem by setting the CD/DVD drive's jumper from
Master to Cable Select. Really weird considering Windows XP and Ubuntu 7.10 were
seeing the drive okay, I guess it's a weird libata issue..
I've esperienced this with the released F8 install DVD using an Optiarc DVD RW
AD-7170A, ATAPI CD/DVD-ROM drive on my Asus M2N-SLI Deluxe mobo (nForce 570 SLI
chipset). The same drive works fine with my son's Abit KT7A mobo (KT133x/KM133
chipset). The Asus board works fine with an NEC DVD RW ND-3550A. The FC6 install
worked fine with the Optiarc DVD drive on the Asus M2N.
The referenced boot options made no difference.
I also having the same problem with Lenovo 3000 N200 0769-CUQ. (with Sata HDD)
Any progress on this, especially for current distros of F8? It is holding up a
lot of people from adopting F8.
You might wish to test a spin from the fedora unity folks:

Essentially there are two issue with this report:
1) The number of disparate bugs make it impossible to address in a single bug
2) The fact that it relates to a distribution release (and is therefore
impossible to resolve at that version point) means it can really never be
resolved within the Fedora 8 lifecycle
I am therefore suggesting the following:
a) All people attached to this bug test with spins from the fedora unity project
as previously indicated:
This _may_ resolve a number of issues which will allow an installable version of
b) Test with Fedora 9 Alpha - due out any day now at:
With all the above I am therefore closing this bug as CANTFIX. Thank you to all
reporters for adding themselves to the bugs and providing requested information
however I hope you understand the reasoning behind this.
Should neither the fedoraunity respins or the Fedora 9 Alpha release be
installable for you please open a new bug against kernel - rawhide and copy
myself into it and I shall endeavour to work with all parties to ensure the
issues are addressed so that Fedora 9 is a release that you can use.
At the risk of stating the obvious, this problem was not reported until F7 and
later F8. There apparently was no problem for F6 and previous versions. What
changed to break what had been working? What is to prevent going back to what
worked for F6 and stick to that except for conservative enhancements that don't
affect recognition of disk drivers, which were, after all, recognized by the
BIOS to load the installer. Perhaps the solution is to remove any code that
overrides the BIOS for that function.
Fedora is not a "conservative" distribution as you seem to imply it is. F7 and
later introduced significant changes to the ATA subsystem (namely abstracting it
via libata). It is not fair to say that no QA went into this, since it works
for most people (myself included - I have been able to install and use both F7
The problem with this bug is that it has turned into a rat's nest of separate
issues. So I'd like to suggest that you take the actions that Chris mentioned
in comment #63 - namely try a unity respin or F9 Alpha, which should hit real
soon (the freeze has already occurred and install testing is taking place now to
prove that the tree as frozen is actually installable).
If you still have problems, please open a separate bug, detailing the exact
hardware that you have that is not working (chipset + drive) and we'll action
My problem, however, is that it is not enough to get it to work on my own
systems. First, it reduces my confidence that later versions will work as well.
Second, it makes me hesitate to recommend Fedora to others, many of whom have a
variety of systems with all kinds of drives and drivers. I submit that we should
be seeking a more robust solution, one that will almost always work if the
installer was itself installed and is running.
I respectfully suggest that an exception handler be inserted at the point where
the installer reports it is not recognizing the drive from which it just
installed itself, and revert back to what worked in F6, which I presume was
loading via the BIOS. In other words, if the libata approach doesn't work, there
needs to be a fallback.
The old approach was to load via the kernel drivers, then new likewise. You are
assuming that these bugs are even driver level. This bug was closed because its
a mash of assorted unrelated, unclassified reports with all sorts of causes. And
despite what you comment older FC's tended to end up with such a random 'it
broke' type bug report too.
No, I am assuming that the installer was loaded through the BIOS, before the
kernel and its drivers could be loaded, because it was executing to even produce
the error message, and that if it could install that much of itself in that way
it should be able to find the rest of itself the same way. I find no previous
bug reports with the same symptoms. Other Linux installers don't seem to have
this problem. I can install using any of them on the same systems. I do not
agree that the reports are unrelated. They indicate a design defect in the
installer that other installers don't have, and that the Fedora installer should
not have, either, if Fedora is to compete with them. Passing the buck to the
respin efforts is not the right approach. I urge it be reopened and kept open
until we can be assured the problem will not recur under any scenario.
The issue here is that the above reports relate to different drivers under
different circumstances. This is the reason the report was closed, not because
we do not believe the problem is not a valid one.
I disagree that testing out re-spins is passing the buck. The unity re-spin
project fills an important gap and offers the chance to have an installable
release should any official installer release bugs appear (which they often do).
I also offered the option of testing the Fedora 9 Alpha release and if this
fails, filing a new bug and copying me into this so that we can work together
with the kernel developers to make sure Fedora 9 is an installable release for you.
Re-opening this bug (which has become the defacto "Fedora does not install" bug)
would solve nothing as the kernel engineers have indicated they are no longer
tracking it due to reasons already stated. Surely you understand that.
Essentially, if you want Fedora installable for you, test with Fedora 9 alpha,
open a new bug (if it doesn't work) and copy me into it. I will be more than
happy to work with you and the kernel team to get it resolved. I detest
installer bugs above all others as I am aware of the large amount of
disappointment and loss of goodwill they can cause.
We are still arguing past each other. I don't see this as a kernel problem but
as an installer problem. The installer that can load the first part of itself
should be able to install the rest of itself, even if there is a problem later
with the kernel or drivers, which should be reported as something like, "Cannot
find driver for disk from which your installer was loaded." In other words, the
installer medium should not be trying to use a filesystem itself that requires a
Linux driver to read it. It should be readable using only the BIOS. Once
installed, it should search the system for drives it has drivers for. So, it
might report, "Found drivers for disks /dev/hdcx, ..., but cannot find driver
for disk /dev/hdcy from which the installer was loaded. Please select one of
these other drives for the installation, or ESC to abort."
I suggest a little light reading - you cannot use BIOS services once you enter
32/64bit mode. No Linux uses BIOS services to load beyond the initrd and kernel
- and you cannot load more without hitting memory problems.

> This bug was closed because its a mash of assorted unrelated, unclassified

It seems to me that this mash is caused in part because the installer falls over
in what *seems* to be the same place for several different reasons, at least in
the default GUI mode.
It's a little late to ask, but what anaconda option would produce a more
detailed running account of what's going on? This bug (bugs...) has been a
total show-stopper on my ThinkPad t61. If I can't install, I can't test/report
on any thing else Fedora...

Alright, so how are the other Linux installers doing it? They don't seem to be
having these problems. I can install SuSE or Debian-based distros on any system
that the F7/F8 installers fail on. Do they come with more drivers? Wny can't we
just borrow the code from their installers for use in the Fedora installer, or
revert to the code that worked for F6, at least as a fallback? There seems to be
a design flaw in whatever was done differently beginning with the F7 installer.
i mananged to get through this by using;
when booting of the spin dvd, i haven't tried it wit the official spin. But
what is reallyyyy annoying is the mouse and keyboard both of which are connected
through usb are extermely slow, does this have anything to do with the acpi=off?
they are both operating incredibly slow.
