Nvidia and SGI 1600SW
Anonymous
support SGI's 1600SW monitor in 1600x1024 mode? Would this work through the
DVI out on the Hercules 3D Prophet II 64MB for example, or would it only
work through the analog VGA output?
If Nvidia is working on this, any idea when they are going to show up? SGI
claims on their 1600sw multilink website that this is in the works, but I'd
like to hear what Nvidia has to say.

MultiLink Adaptor required as well), but only on the GeForce 1, because it
uses an external TMDS Transmitter. The GeForce2 GTS, with its internal TMDS
transmitter, only supports 1024x768, and no other resolution.
You will have to look to the GeForce 2 Ultra with and Extrnal TMDS
trasmitter, as there are no GeForce GTS cards with one.
The drivers are required to support 1600x1024 AND a special timing mode for
the 1600SW. The drivers support this resolution, but not the special timing
mode.
I hope someone puts our drivers soon, I have a 1600sw and I would love to
get a current fast card on it.
I have used a Geforce 2 prophet 64, and it works up to 1280x1024 in alalog
mode, and is very sharp. I also used a few 3dfx cards, also very sharp up
to 1280x1024, Tribes looks awsome on the 1600 in glide mode!!!

one resolution" when they sell the 3D Prophet II GTS 64mb and claim it
supports DVI (implying that it supports it like it supports VGA-out, in all
resolutions). I can verify that it doesn't work in others, not that you
have any doubt, but in case others read this and wonder. It doesn't help
that Nvidia *sometimes* claims that to support DVI in the GeForce2 chipset.
See http://www.riva3d.com/dvi.html for some interest comments there.
I tried getting the Multilink adapter to interpret 1600x1024 output from the
analog out of the Number Nine that ships with the 1600sw, but the Multilink
didn't like that resolution, raising the question of whether the card that
ships with it doesn't have the proper driver either, or whether the
Multilink doesn't support 1600x1024 through the analog input. I guess we'll
see as other cards claim to support the Multilink adapater.
Do you know if anyone has gotten the GeForce1 cards to work with 1600x1024?
Would there be a timing issue for the DVI output, or just the analog VGA
output? You can modify the driver .inf to include the resolution, though
that can have varied effects depending on the drivers.
Has anyone tried the Matrox G400 with DVI? Any results?

That would be my guess. I just learned today that the 1600SW requires that
the video blanking interval (one of the timing parameters) be very short
in order to work with full resolution with the MLA in analog mode. If you're
running (say) XFree86 and the card's timing registers support the needed
value, you could try cranking the blanking interval value down in the
XF86Config...

It does, you just have to use the correct blanking interval timing
(so I was told today).

Just a note - I've personally had the SGI V3 and VR3 graphics (based on the
Geforce 256 and Quadro chipsets) working under Windows NT 4.0 at 1600x1024@
60 Hz via the DVI port. I'll be testing the Windows 2000 drivers today, but
don't expect any problems.
Note that the drivers require a flash BIOS upgrade of the graphics card, so
they can't be used with non-SGI versions of these chipsets. These are in
final testing, and should be released via Supportfolio or
www.sgi.com/flatpanel/superwide_savvy.html soon.
Cheers,
Ben

I'd hate to wait for Hercules/Guillemot to release a new firmware (not BIOS
for heavens sake!!! A bios is a specific piece of firmware in my book).
Can't I just ask nicely for SGI firmware?!

I believe that nVidia's firmware utility checks to see what vendor made the
graphics card, and will only allow that vendor's firmware or nVidia's
reference software to be installed. If you do install nVidia's reference
firmware, you can no longer install the vendor-specific version.
I haven't tested this, because I don't feel like having a useless card
sitting around.

than flashed it back to my vendor's bios.

A lot of things -- for starters, a VR3 is Quadro-based, not
GEForce-based, with a core clocked faster than other Quadros, and is
always 64MB DDR.
Note that even the (Quadro-based) ELSA Gloria II Pro 64MB DDR and the
VR3 are different -- an ELSA BIOS for these particular ELSA cards will,
as an example, refuse to work on a VR3.
The NVidia drivers may be unified , the BIOSes aren't -- and flashing a
V3 with a VR3 BIOS doesn't work either.

ati radeon, the Geforce 2 Ultra, will again have an off chip DVi (tmds)
transmitter, so there is hope.
BTW,
I am the one that finally persuaded Riva3d to do the dvi article. :)

Nope, the NVFlash programs only check the PCI VendorID (Which is the
ID of NVidia, not your manufacturer) and SystemID (Which is the type
of chip on your card).
The PCI SubVendorID (Your manufacturers ID) and PCI SubSystemID
(Another manufacturers ID only more specific to the card type) aren't
checked by NVFlash.
The flash program of other manufacturers do check for the correct
SubVendor/SubSystemID so make sure you make a backup copy of your BIOS
with NVFlash before you start flashing the reference BIOSes.
