I found a procedure I want to try before giving up on this. Points
against the dvd-burner failing:
- The media IS bootable.
- Each file on the media is readable and has md5sum matching the same
file in the .iso image on disk.
- Fedora mounts the media
If I buy a new drive and it turns out that it wasn't faulty, it'd be a
waste of money.
The procedure I found comes from an Ubuntu bug report, and can be found
here, (where it is explained):
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/24022
Here it is:
Step 1: Startup the installer and go to console 2 directly, before even
selecting a language.
Step 2: Press enter to activate the console.
Step 3: modprobe ide-cd
Step 4: modprobe ide-core
Step 5: modprobe ide-generic
Step 6: hdparm /dev/cdroms/cdrom0
At this point it should tell you "IO_support = 1 (32-bit)"
Step 7: hdparm -d1 /dev/cdroms/cdrom0
Step 8: Switch back to console 1
Step 9: Proceed with selection language etc - everything will work now.
At step 2 nothing happens when I press enter. I can switch console
(seemingly?) using Alt-F2, but it does not get activated. In consoles 3
and 4 there are output from the boot process, naming, among other
things, modules that are loaded. Close to the end of one of the lists, 3
modules are loaded: forcedeth, libata and sata_nv, in that order. While
not identical to the bug report, I'd like to have a go at the procedure,
just to see if it makes any difference.
Under FC6, are there extra consoles set up in the install boot image, so
that I can follow the steps above, or is there a defferent way to
achieve the same result?
