linux on Intel D915GOM oops

[Henti Smith]

Hi guys,

I've been given a mecer Xhibitor media center machine to try and get
linux on for testing. 

The machine seems pretty much limited to South Africa, however the
setup is used by other companies like
http://www.higrade.com/nqcontent.cfm?a_id=3539 and
http://www.alienware.com/product_detail_pages/DHS_2/dhs_2_features.aspx?SysCode=PC-DHS2&SubCode=SKU-DEFAULT
which use the same mainboard atc. 

for more information ont he mainboard used:
http://www.intel.com/design/motherbd/om/om_documentation.htm

I've tried to boot just about every linux distro I can get my hands on
and they all oops at bootup. 

Unfortunately I cannot get to the first few lines (screen cannot scroll
after oops) 
but here is what I can get to : This is booting with Ubuntu

any ideas on what the problem could be ... or how to get around it ?

this is the known bug where by default Linux uses the BIOS services for
PCI rather than the native method.

try putting

pci=conf2

on the kerenl commandline

(and you may want to try a kernel newer than 2.6.8 btw)

It's a BIOS bug if the PCI BIOS doesn't work, not a Linux bug.

it's a bios bug if it doesn't work.
it's a linux mistake to depend on the bios for this in the first place
(since other OSes don't use this afaik)

The patch that fixed the order changed it just from random to 
consistent.

But as discussed earlier if someone can show that 2.4 did it the other
way around consistently we can change the order to be like 2.4.

Thanks Arjan, I can boot now .. tho everything else after that goes to
a ball of shit .. still trying to get it up and running for an install
hehe 

I had to use acpi=off as well ... this main-board doesn't seem to be
very stable ;P

No that trace is a bug in the BIOS. Ask the vendor [politely] for a BIOS
update, and if you can find a good technical contact the trace may help
them

conf2 or conf1 ??
