I have a Leadtec Motherboard (WinFast k7ncr18) and I wan't to install
a better video card. There is an AGP slot. I have found instructions
on the Nvidia site for doing this but I can't find any info on what's
needed on the motherboard end like jumper settings or BIOS changes.
Nothing in the Leadtec manual or site. Anyone know if I need to do
anything special? Thanks.

Unplug PC. Put the card in the slot. Push. Plug in PC. Turn on.

I bought one of the models for a neighbor. If I remember correctly
theres a thing in the bios under - init display . Thats in all the
boards I have but they usually only list AGP and PCI but I think
theres an option for onboard display for that board since it does have
it built in. Thats it I think. Just set it to AGP.

With any motherboard that has integrated video on the
northbridge, an "AGP" ported solution (as anything made for
a PC in the last 5+ years would be), all you have to do is
plug in the AGP video card, it must automatically disable
the onboard video because AGP is a port, can only have one
device on it.

I wish I knew what to do with one of my boards Dave. It's a cheap GA-6VEML
rev 1.2 (As best I can tell, it has another number stamped partially over
it).

It doesn't have an AGP slot so I got my hands on a second-hand 32MB GeForce
2 and the video is heaps better. However, I can't find a way of disabling
the on-board video in the BIOS and during the RAM count it's 8MB short, the
amount the OB video used.

It's only running a Tualatin Celeron 1.2Ghz so I'd like to disable the OB
video if possible as I have a sneaking suspicion it's still eating up CPU
cycles drawing pictures that aren't going anywhere.

Cheers,

IIRC, some boards can't disable the AGP video when a PCI
card is used. I think it was the low-end Via chipsets that
behaved this way. I have a fairly similar MS board here
with (same?) PLE133T chipset and looking at an archive I
made for it, I'd written: "MS-6368 Onboard Video cannot be
disbled, this is a limitation of the chipset. ".

The three things you could do are:

1) Set memory allocation to lowest amount possible in bios.

2) Use a PCI Latency adjustment tool (even though it's AGP)
to reduce it's latency to a minimal value.

3) Disable it in Device Manager (may eliminate the need for
#2).

I don't think it would be eating up cycles drawing pictures
though, unless windows considers it the primary display
there shouldn't be any output to it, AFAIK... you would have
to use Display Properties to enable it as a secondary
display to cause that.

That's the same chipset. Bloody horrible thing but I was given a few with
Celeron Tualatin CPUs in and didn't have enough BX boards to fit Upgradeware
Slockets in so am still running one of the PLE133T-based boards. They also
all had bulging/leaking caps but I replaced the ones on this board.

There is no adjustment. It's 8MB and there's nothing I can do to change it.

Thanks for that, I've downloaded it and will play.

Not possible unfortunately. It seems they never intended anyone to use
anything other than on-board video with this board. The *only* option in
BIOS is "Init Display First". Options are PCI and AGP and the default is
PCI. Also that's what it was already on.

Hopefully it's not uselessly using cycles to do nothing. :-)

Thanks for your help Dave, good to 'see' you again.

I kinda like them... their performance is as good as BX, but
they support AGP4X if/when they have the AGP slot, plus they
accept high-density PC133 memory. I have over a Gig of
PC133 memory lying around and will probably turn one of
those (or the non-integrated video Apollo Pro version) into
a fileserver.

As for the caps- yes I had some Gigabyte boards with bad
caps too, even have one in front of me now (6VX7B-4X) which
happens to be same or very closely related to a board Tom's
Hardware ranked very well back in the day- and that I'd used
to build several systems for others. Fortunately most (if
not all) of those boxes had Coppermines so the amperage dawn
from the onboard regulators wasn't as high... they haven't
failed *yet* AFAIK.

There is no adjustment. It's 8MB and there's nothing I can do to change it.
Click to expand...

Oh well, at least it's not stuck at 32MB. I don't know if
you could edit the bios with an (AMI?) bios tool or not,
perhaps enabling a feature to change the size of the
allocation. It could be that 8MB was a minimum though, I
don't remember.

Thanks for that, I've downloaded it and will play.

Device Manger - Windows - Disable it.

I guess they're ok. I don't know about "as good as a BX" though as I put two
of the Celerons (1.3 and 1.4Ghz) into MS 6163 pro boards and they're doing
SETI WUs in about 80% of the time they took in the PLE133T boards. I have to
have fans blowing on the FETs though. ;-)

Yeah, I've never edited a BIOS and I don't think it's worth it really for
this old clunker. I guess 8MB isn't too bad. The guy I got them off had them
running in a SETI farm and he said that reducing the resoution and colour
depth increased WU throughput even though they didn't have monitors hooked
up. (He telneted into them). That's what made me wonder if the OB graphics
was still drawing CPU cycles even though I have a PCI card in.

D'oh! Must learn to read huh? Yes, that's the first thing I did.

80% with the PLE133T boards using the integrated video or
not? I'd expect there are some things BX is better at, but
being older it has other limitations too- I just don't judge
older gear based on performance as much as features &
technology support I suppose.

Cool. <fingers crossed>
Click to expand...

Yeah but they weren't running Tualatins and more
importantly, they weren't running at full load.
One MSI PLE133T buard here running an overvolted, o'c 1.5GHz
Tualatin couldn't handle the amperage so well, it's caps
were getting quite warm during Prime95 testing. I ended up
replacing the caps now (then) rather than waiting for them
to fail- I really dont' want to touch a box after it's set
up except maybe to blow out the dust every year or two.

If the integrated video were still the primary active
display adapter that would be true (about lowering
resolution and bit depth) but AFAIK it's only a matter of
whether it's the primary, not whether a monitor is
physically hooked up.

Didn't it help the WU?
