hi there,

i was wondering if someone can help. I am trying to install Red Hat update 4 i386 with intel core 2 duo and Intel DG965RY motherboard with 4GB of Kingston RAM. When i start the installation the installtion stops at Probing PCI hardware bus 00.

Has anyone successfully installed RH on this environment? Is there something i am missing. I have tried Linux noprobe option but that is probing the hardware.

Any help will be appreciated and thanks in advance.

Your problem is two fold.
First, you need to add "pci=nommconf" to the kernel boot parameters;
Second, This particular board isn't currently supported by Redhat 4 update 4.

There is a patch for the ata_piix driver that Intel released, but RedHat didn't take it before they released 4u4. I'd recommend either waiting for 4u5, or Novell Suse Linux Enterprise Desktop 10 works quite well with that system. Or, you could install RedHat onto a hard drive from a different system, then patch the ata_piix driver in the kernel, and move the drive back.

Hi guys,

Please let me know where can i foung ata_piix driver any link etct etc .

Even i m having same problem of booting of RHL4 with Intel DG965RY Mother Board where its getting stuck on

"When i start the installation the installtion stops at Probing PCI hardware bus 00. "


Any pointers link please for this Driver.

Cheers,

I have the same problem on DQ965GF Intel board.
i want to install RHEL4u4 on the new system, but i get "Probing PCI hardware bus 00."

I want to install it on 80GB S-ATA HDD, but RHEL does not recognize the S-ATA controller, so i've tries to use a PCI-SATA controller - nothing.
HELP!!! Please...

To get past the "Probing PCI hardware bus 00" hang, you need to boot with "pci=nommconf" on the kernel cmdline on the 965 systems. Also, the DQ series boards will install if you change the sata mode to legacy.

What does this option ("pci=nommconf") do? And does anyone know why this fixes the problem, I'm having the same issue with SYSLINUX.

i was wondering if someone can help. I am trying to install Fedora Core 4 i386 with intel core 2 duo 1.86 GHz and Intel DG965RY motherboard with 1GB of Kingston RAM. When i start the installation the installation stops at Probing PCI hardware bus 00.

Has anyone successfully installed Fedora on this environment? Anyone can help me

hmm, it took me a while to figure it out, but a while back they added support for memory mapping to the PCI Bus. That could cause problems with some cards or bridges I suppose, so pci=nommconf probably means no-memory-mapping-configuration on the pci bus. Don't take my word for it but it makes sense.

Did you try the pci=nommconf ? It didn't work for my card (RedHat 9/Krnl 2.4 does not recognize it), but if the PCI bridge on your DG965RY doesn't support linux pci memory mapping that option will allow it to finish probing the bus.

when you install the system and it asks you for parameters to boot with type "pci=nommconf" and what ever other parameters are needed.

FC4? You'd have better luck with Windows 98. Seriously, older distros really don't work well with the new hardware from Intel. Try FC6, Mandriva 2007, OpenSuse 10.2, Ubuntu (latest), etc. Otherwise, you'll need to upgrade the kernel, audio drivers (alsa-1.0.12 minimum), and video drivers.

Also, go to support.intel.com and make sure you have the latest bios. I'm currently installing Mandriva 2007 on a DP965LT (functionally equivilant to your system w/o graphics). My SATA is set to AHCI and working fine (except for the Plextor SATA DVD-RW).

Hi Aswin

I've the same config & the same problem.

for installation pass this parameter when the main menu appears

linux acpi=off

---- It worked , completed the installation .

but the Intel Network pro NIC is not detected in this case.

hey.

well some time has passed and RHEL 4 update 5 has been released but still it doesn't work, and I`ve also tried RHEL 5 and it still doesn't work..both ask for that ata_piix driver.
could anyone please tell me how to fix this..or where to get the driver. i'm in desperate need.

thanks a lot.

Here's how I got it to work on Redhat Linux AS 4 Update 4:

During installation, put "linux pci=nommconf" at the linux boot prompt.

After successfull installation, server reboots. You will get the grub menu. Select the kernel you want to edit, and press "e" to edit. Move the cursor down to the "kernel" line and press "e" to edit that line. For me, my line reads:

kernel /vmlinuz-2.6.9-42.ELsmp ro root=/dev/VolGroup00/LogVol00 pci=nommconf rhgb vga=extended

Press ENTER to accept the changes.

Press "b" to boot.


Once you're successfully booted, check your /boot/grub/grub.conf file so that the above changes take affect permanently. Mine is the following:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
default=0

Hi,
i am having the same problem, i could boot my system using option of "linux pci=nommconf" but problem comes when when it skes for selecting drivers for devices. Its not deceting my SATA hard drive on my core du2 system. How to resolve this issue? I insetred the CD came with my machine from INTEL but it doesn't pic any driver from there

Regards

You may need to change the bios setting for your SATA controller. Either set it to legacy mode or ahci and specify the ahci driver in Linux.
