Description of problem:
My primary adapter is a ATI Rage128 PCI. Secondary is Elsa Geforce2 GTS AGP.
Rage is only used at boot time. X Windows uses the Geforce2. If the BIOS is set
for a PNP OS this configuration will fail. The kernel PNP code does not properly
initalize the secondardy Geforce2. Symtom is failure of NVidia kernel module
when initializing X.
Setting the BIOS to non-PNP OS makes the config work.
Win2K works with BIOS on either setting.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install primary Rage128
2. Install secondard NVidia Geforce2 GTS
3. Set BIOS of PNP OS
4. Boot Linux
5. Config X to use GF2 with NVidia kernel support
6. Start X.
7. X will fail with "unable to initalize hardware"
Make GF2 primary adapter or BIOS non-PNP OS and config will work.
Actual Results: X will fail with "unable to initalize hardware"
Expected Results: X should have started
/proc/pci when non-PNP OS set in BIOS:

If X is failing to find the hardware based on BIOS settings, this is an XFree86
or kernel problem, not a kudzu issue.
1) don't set the bios to PNP, that's not supported
2) the binary only nvidia driver is not supported
Indeed, Nvidia binary kernel modules are unsupported. Closing as dupe
of our dupe catcher.
*** This bug has been marked as a duplicate of 73733 ***
I don't agree that this is a duplicate of problems with the NVidia driver
(73733). arjanv was correct when he said don't set PNP OS in the BIOS because
it is not supported.
Something is wrong with the kernel's PNP assignment of resources at boot time,
this is before any NVidia driver code is loaded. Loading the NVidia code just
illustrates that the card has not been initializaed properly.
I suspect that the ROM BIOS for the video card contains an initialization
routine. The kernel's boot time PNP code is not calling this video BIOS code.
When the card is the primary video card or non-PNP OS is selected the
motherboard BIOS calls the video BIOS to initialize.
If this occurs at boot time, then it may be valid. Feel free to reopen
if that is the case.
Just be sure for any bugs that you report in bugzilla while using
Nvidia hardware, that from kernel boot onward, the Nvidia binary
kernel modules have never been loaded. Even loading them, then
unloading them is enough to corrupt the kernel, and will make your
arjanv said that PNP OS in the BIOS is not supported. I'd file this bug with
the PNP bugs so that when it is decided to support BIOS PNP OS we'll still have
the bug report. Right now the kernel tries to do PNP OS support but it doesn't
always get it right.
No, the kernel does ISA PnP, which is Plug and Play for the ISA bus,
not for PCI devices.
It is highly unlikely that the kernel will ever support the PnP OS
setting in PC BIOS's, largely because there is no real reason for
Right now you're just grasping at straws to try and guess what the
problem is that you are having. That isn't helpful. At any rate,
this isn't an XFree86 bug, so I don't need to see it anymore.
