Nvidia RIVA TNT card conflict

[nerp]

Hi

A friend had upgraded to Win98 and his computer began to behave strangely.
He asked me to help and we decided to format the harddisk and reinstall
Win95, to clear everything up. It went pretty smoothly until it came to the
video card. He has an Nvidia RIVA TNT card; I used the Riva TNT drivers
that we had on CD, but Win95 kept reporting a conflict. I don't quite
understand why it would be reporting a conflict now, since it was working
under Win98 and we did not change any of the hardware when we reinstalled
Win95. Anyway, I downloaded the latest drivers from Nvidia's site but the
same problem continues to occur. The settings for the Nvidia RIVA TNT card
are as follows:

Memory Range 000A0000 - 000AFFFF
Memory Range 000B0000 - 000BFFFF
I/O Range 03B0 - 03BB
I/O Range 03C0 - 03DF
Memory Range EE000000 - EEFFFFFF
Memory Range E4000000 - E4FFFFFF

Windows says the last two memory ranges (EE000000 and E4000000) conflict
with the "PCI Standard PCI to PCI Bridge." I'm not even sure what the PCI
to PCI Bridge is, so I am really stuck! I tried adjusting the latter two
memory ranges for the video card so it would not conflict, but it then just
reports the card as not working properly. I also tried adjusting the
settings for the PCI to PCI bridge so it would not conflict but that still
did not solve the problem; Windows still reports the video card as not
working properly. I wrote down the original resources used by the video
card under Win98, and they all match the resources that are being used under
Win95, except Win98 listed two other memory ranges (starting at 000C00000
and EDE00000) and one IRQ (12) that aren't even listed under the nvidia
card's settings in Win95.

The PCI Standard PCI to PCI Bridge settings are as follows:

I/O Range C000-CFFF
Memory Range EDE00000 - EFEFFFFF
Memory Range E3C00000 - E5CFFFFF

I went to Nvidia's site hoping to find some help, but they don't offer any
support! I'm not sure at all who else to ask for help. They said to seek
out the manufacturer of the card for support; the only text I have on the
card refers to it as an Nvidia RIVA TNT card, and there is no other company
name. If anyone can offer any help, I would really appreciate it. I feel
really bad because I was trying to help a friend with his computer, but
instead I created an even worse problem.

Thank you for any help,
Ryan

I just wanted to add that the card uses an AGP slot.

Has it caused any actual problems at all? I've heard that this is a
quirk with Win95 and AGP cards that really doesn't cause anything to
go wrong. If it works fine, then you can just ignore it.

Win95 OSR2 had the pci bus/memory conflict, but win98 supposedly fixed the
problem. However, if you're running a VIA chipset, the memory range conflict
due to AGP/DIME memory sharing may still get reported as a conflict. I
don't remember checking this "feature" the last time I installed win98 on a
VIA based system, but the range of conflicting addresses looks just like an
OSR2 system report.

Hi,

This is normal with windows'95. The reason is that win'95 was written
before AGP and windows'95 does'nt know how to handle the PCI to AGP Bridge
and reports it as a conflict. According to Intel's support site this will
not cause any known problems with the functionality or performance of
windows'95. You can visit intels support site and search on agp for the
actual article.

HTH,

Glynn

Although I can't verify this at the moment, I would imagine that is already
set because the card was working fine under Win98. We didn't change
anything at all. We merely formatted the harddrive and installed Win95; no
hardware or BIOS changes. I will check to be sure next time I'm at his
computer though.

Thanks,
Ryan

Hi,
I'm having trouble with the card though; I cannot set it above 16 colours!
The other colour options are listing in the display settings, but if I
select one it remains in 16 colour mode and either says the card is
conflicting or that it is not configured properly. If the card was working
fine and reporting a conflict I wouldn't worry about it, but it's not
working properly. I have the latest drivers and I haven't changed any
hardware settings at all after formatting the harddrive and installing
Win95. I can't understand why the card is no longer working.

Thanks,
Ryan

The card won't work though; I can't set it above 16 colours! The other
colour options are listed (like 16bit, true colour, etc. etc.) but if I
select one it remains in 16 colours and says there is either a conflict
(with the PCI to PCI bridge), or that the card is "not configured properly,"
when I adjust the settings so there is no conflict.

Hi,

Try going to the following link and downloading the appropriate chipset
download for your motherboard. These will initialize the proper PCI Bridge
drivers in Windows'95 and then try to load your video card drivers after the
machine finishes rebooting and setting up the PCI bridges. To check if this
is necessary go into the system properties from the control panel and check
for the PCI bridges in the unknown devices category.

This is not the cause of the problem, Windows 95's Device Manager doesn't
know how to report the resources for AGP cards properly, so this shows up as
a conflict. Are you using the OSR2 version of Windows 95 with the USB
supplement? You need to be for AGP. It really is best to use Windows 98 for
AGP cards.

Hi again,

The PCI to PCI Bridge exists under the 'System Devices' catagory; there's a
couple references to the USB under the unknown devices catagory, but no
mention of the PCI bridge. I might give this link a try anyway though. I
need to get my friend's computer up and running again. :)

Thanks for the help,
Ryan

Hi
I see.. I'm relatively certain it's the OSR2 version of Win95 (cannot
verify this at the moment but I'm almost postive it is). It does include
the USB support, btw. However, if memory serves, the USB is falling under
the 'unknown devices' catagory in the device manager. He has the Win95 -->
Win98 upgrade; if we upgrade to Win98 again, should that correct the
problems with the video card?

Thanks for the help,
Ryan

If you install support for USB that might help the problem. Should be on the
Win95 disk, usbsupp.exe or something like that. The 'conflict', however, is
cosmetic.

I installed the Win98 upgrade and that solved the problem. Thanks for the
help!
