Hello-

I got a new motherboard/cpu (Intel DG965WH w/Intel CPU Pentium D 820
2.8Ghz dual core.
I took a working fed 6 HD and stuck it in and it wont boot, it
complains during bootup saying:

....
Red Hat nash version 5.1.19.0.2 starting
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: no such file or directory
setuproot: error mounting /proc: no such file or directory
setuproot: error mounting /sys: no such file or directory
switchroot: mount failed: no such file or directory
kernel panic - not syncing: attempted to kill init!

then it freezes.

I took same working disk and put it in my windows box (switching out
the HD temporarily) and it boots and works just fine (its an older
motherboard/cpu).

next:
I thought Id try to use the fedora 6 rescue disk and see if it might
somehow
correct itself (even though nothing seems to legitimately be wrong
with it).
Now it boots up the fedora rescue and I go through the menus. Just
after
the language -> keyboard type -> I get to the menu that says:

Rescue Method

What type of media contains the rescue image?
Local CDROM
Hard Disk
Floppy Drive
FTP
HTTP

When I select CDROM (duh, I just boot from there), it says:

unable to find any devices of the type
needed for this install type.
Would you like to manually select your
driver or use a driver disk?

OPTIONS: Select Driver Use Driver Disk

At this point Im lost. Is it saying that it no longer has a driver
for the CD rom its
reading the disk from? If so why not?? How did I get this far?

I tried putting in another HD and installing fed 6 from scratch, but
it
complains about the same issue. With a new motherboard and CPU I
didnt
think this would be an issue.

Anyone know what this is and how I should resolve it?
Thanks,
Jeff

That translated means: the mobo has a strange disk controller that your
kernel doesn't recognize

See previous point.

What kind of hard disk, SATA or PATA? You must use the "all-generic-ide"
kernel option to access any PATA drives. If it's a SATA disk make sure
the SATA controller is set in AHCI mode in the BIOS.

Again, you need to use the "all-generic-ide" option to use PATA drives.
The kernel and the initial RAM disk image are read using BIOS code, but
you need a Linux driver to proceed past this point.

The motherboard is _too_ new. You would need kernel 2.6.20 or later to
use the Marvell PATA controller without any extra options. The FC6
installer uses kernel 2.6.18.

I have the exact same configuration, and had similar problems.
You have to:

1) Set AHCI mode in the BIOS

2) At the installer's first screen (Before starting the installer)

linux all-generic-ide pci=nommconf

This will boot and install successfully.

Thank you very much Jim for this info, however, I didnt see
AHCI mode anywhere in my bios? Can you point me to it?

And I assume you mean that the linux all-generic-ide pci=nommconf
is an argument to the kernel during boot up? Ive never done that
before is why I asked.

Thanks again!
Jeff

AHCI is set in the IDE disk configuration page. The options are
IDE or AHCI.

Yes. At the very first screen, where you'd normally press ENTER
to boot and launch the installer, enter the linux... command and
press ENTER.

Bah, nevermind, I found both. Thankyou!

You could try out Fedora core 7 test 2:

http://torrent.fedoraproject.org/

the FC7 Test 2 just got posted today on there, I bet it has 2.6.20 in it.
I have FC7 Test 1 on my laptop and it's at 2.6.20 something for the
kernel. You could just try the f7-test2-livecd-i386 and use it to
confirm that it works on your hardware before having to
commit anything to disk. It depends on what you want to use
this machine for and if you can accept some occasional odd occurances
(something will work, you do an update and it quits working, then
a day or two later another yum update will fix it..)
