[486 PVI/SP3 mainboard] need pci graphics card with dvi connector

hi,

i own an old 486 pvi sp3 mainboard from asus. since i bought a new tft
i want to connect the 486 through dvi.
the main problem is finding a pci graphics card that has a dvi
connector and which is working together with
that board (since now i'm using a matrox mystique pci in that
computer; anyway a diamond viper v330 works, too).

tried so far a geforce 5200 and a matrox g450. but the 486 won't boot
with these cards. there is no post, no beeps.
what is causing the 486 not to boot? could somebody please help me?

thanks in advance!

What you are trying to do, in short, is not possible.

Not quite sure I know what you're asking, but it sounds like you maybe need
to uninstall old video drivers.

It doesn't boot due to a bug in the old Award 4.5 bios core that Asus used
that causes it to not boot if the video card has more than 32MB of video
RAM. 32MB is probably fine, 64 or more is definately not. You probably
will not find a fix for this. Unfortunately cards with 32MB or less usually
don't have DVI ports on them so I think you won't be succesful. You'll have
to live with using a VGA port.

ok. and that is why?

The first question to ask is, do modern video cards
and their video BIOS chip, work the same way as
video cards from the 486 generation ? Maybe your
motherboard BIOS is becoming confused by either
something it is seeing in the PCI config space,
or your motherboard BIOS is attempting to load
the video BIOS, and the two BIOSes are not compatible
with one another.

My first question to you would be - does your new
LCD monitor have a VGA connector ? Could you use
the VGA instead ? If I was buying an LCD monitor,
I would want both a VGA and a DVI connector, and
not be limited to just DVI-D only. There are too
many situations where you would be wanting a VGA
connection, to consider buying monitors having only
a DVI-D option.

If you cannot succeed in getting a modern PCI card
to deliver a DVI-D signal, and POST on your computer,
you could consider one of these - a VGA to DVI converter.
But the price of these units, costs as much as a
new monitor.

Interesting, I never heard that, but then I never tried a 486 with
more than 32MB video RAM... Probably no more than 2 or 4 MB back then.

Unfortunately cards with 32MB or less usually
don't have DVI ports on them so I think you won't be succesful. You'll have

Google for pci vga dvi 32mb finds at least Matrox Millennium G450 PCI
and ATI Radeon 7000 cards. I actually had that Matrox years ago. These
cards should still be findable.

thank you very much for your reply, i have already tested a matrox
g450 with 32mb ram, with no success.
i'll try to find a g450 with 16mb

That Board is not the best choice.
Better go with a Saturn-II Chipset. ASUS SP3G for example, with real
PCI (fast).


The highest card I ran on a 486, was the Matrox Millenium II with 16MB
WRAM. G200, 400, 450 PCI-variants should work as well!

I guess some 486 boards cannot use more than 32 or 64MB RAM total
(128MB total, for/with the Saturn-II 486 PCI/ISA Chippset).
Cards with many Video RAM may cause troubles in such small 486
environments, even the 486 itself can address much more RAM. More a
Board or BIOS trouble, IMHO...

P.S.: Why do you want to use a lame DVI connection, with reduced colors
and many other disadvantages, not to mention the pixy, slow, tearing
and ugly TFT screens?
