P4P800S AGP problem

Euan

System:

P4P800S
P4 2.6C
512 MB (one stick)
500 watt power supply
Serial ATA Samsung Hard drive
ATI Radeon 9700 graphics card (version 30 as per motherboard manual)
Windows XP Professional

Device manager shows two un-recognised devices:

Video controller
Location: PCI bus 1, device 0, fuction 1

Video controller (VGA compatible)
Location: PCI bus 1, device 0 function 0

I'm confused as to why XP is picking up my AGP card as a PCI card, and
assigning two resources to it to boot. Using stock BIOS and provided XP
drivers.

Anyone come accross this before and know how to resolve it?

Thanks,

Euan

You need to install the motherboard chipset drivers, as in INFINST.exe.
That should make your problem go away. Your video card may insist on
having its drivers reinstalled after you do this. The latest drivers
can be found here on the Intel site, but your CD will also have them.

http://developer.intel.com/design/software/drivers/platform/inf.htm

A complete install consists of chipset drivers for the motherboard,
AGP drivers for the video card, and some version of DirectX for
Windows. This gives you the appropriate software "stack" for 3D
applications. Without an AGP version of a chipset driver, the
AGP slot runs in PCI mode.

An uncorrupted manual is here. See page 79:

Thanks for the reply Paul.

Unfortunately following those links changed nothing; exactly same errors
as before. The pdf's taking a time to download, maybe there's something
in the BIOS that I missed. I'm using the default settings.

Thanks,

Have you tried Windows Update ? I have no idea if that has ever
fixed chipset driver issues before or not, but it is another source
of downloadable stuff.

To try and find an answer for you, I downloaded the Intel INFINST
from the webpage, then used the option to just dump the INF files
into a directory.

From a DOS prompt:

infinst.exe -A -A -P D:\temp

will put the INF files into D:\temp. It will look like the installer
is running, but it ends up just copying the files into the
directory specified by the -P option.

Looking in there, for an ICH5 southbridge board, there is support
for 865/875 northbridge boards, but the 848P is not mentioned.

By downloading the Northbridge datasheet for the 848P from here:

http://developer.intel.com/design/chipsets/datashts/index.htm?iid=PCG+devleftnav&

and comparing it to an 865PE datasheet I already had, they seem to
have the same Device Identification numbers

VEN = 8086 DEV = 2570 DRAM controller
VEN = 8086 DEV = 2571 PCI to AGP bridge
VEN = 8086 DEV = 2573 PCI to CSA bridge
VEN = 8086 DEV = 2576 Overflow device (Host to HI, some memory stuff?)

Both the 865 and the 848 use DEV 2571, and my guess is the 865 stuff
is supposed to work for the 848P as well. I don't know if you can tell
from the entries in the Device Manager, whether they are from the
video card or from the northbridge.

Do you know of a way to dump the contents of the Device Manager
as a text file ? Maybe posting more info about the contents of
the Device Manager will help identify what is wrong. It is funny
that Intel hasn't updated the INFINST, even though the 848P was
released - so I presume the 848P is considered a subset of the
other chipsets, and so is "automatically" covered.

I see very few posts about the P4P800S in Google, so there weren't
any solutions in there. There also wasn't anything of note in
abxzone.com. I didn't slog through all the posts on abxzone found
by searching for P4P800S, as some of the threads on abxzone are
monsterous.

I don't know anything about your card, or that motherboard, so I am just
guessing, but does the card have other devices that might need drivers?
