Hello
I've done a bit of reading on a 8514 Graphics card I have, and understand that it displays only a very specific resolution /refresh rate s 1024 x 768 / 256 colors @ 43 hurtzzz, and is useful for fast drawing of vectorized graphics... ok cool.
From reading the card is suppose to use the Auxiliary Video Extension to sort of pass through VGA from the onboard out the graphics card.
What I want to understand better is this bit of text:
"8514/A Display Modes
The IBM 8514/A only supported two resolutions: 640×480 and 1024×768. The basic 8514/A with 512KB VRAM only supported 16 colors; the 512KB memory expansion brought the total to 1MB VRAM and supported 256 colors as well.
The very limited set of resolutions was purely a function of the 8514/A display controller—the accelerator was much more flexible, and in fact 8514/A clones often supported 800×600 and 1280×1024 resolutions as well. The limitation was a consequence of only two oscillators on the board (and no programmable PLL), providing 25.175MHz and 44.9MHz pixel clocks for the 640×480 and 1024×768 resolutions, respectively.
"
So 640x480 is supported, anyone?
from
https://www.os2museum.com/wp/the-8514a-graphics-accelerator/
Indeed the graphics card does have 2 oscillators on it.
Q1. Is it possible to use this card at 640x480, or would that be coming from the onboard?
Q2. When I've installed this card into my system, I installed the ADF and can see the card and its resources listed, however there is no display output at all, it is plugged into the MCA slot with Auxiliary Video Extension... So does that mean this card does not pass thru the AVE? Or it does and mine is simply broken? Maybe I missing the big picture here...
Q3. Could changing the oscillators lead to the use of different resolutions? ( probably have to fiddle with driver, adf as well , who knows what else).
This info is somewhat contradicted by the 8514 specific page on ardent tool, which lists only 1 resolution supported for it.
Anyhow it probably isn't the best card to use, but it looks cool, and I'd like to if I can tolerate the 43 hertz, or run it at 640x480 instead, if that is even possible.
Thanks,
Jonathan

You pose some old [but good] questions. AVE and 8514 are not my cuppa Joe...
https://www.ardent-tool.com/video/8514.html
The 8514 page on the Tool DOES sorta mention the two resolutions, but
only points to the 1024x768 as the only one actually produced by the
8514/A, the 640x480 carried over from the AVE... BUT that is a good
question, why is the 25.175MHz oscillator installed?
The AVE and BVE thing is not altogether useful for anything higher than
640x480.
https://www.ardent-tool.com/video/Video_Extension.html
Just as an exercise in mental gymnastics, can you install the 8514/A in
a NON-AVE 16-bit slot? When you stick it into a 16-bit AVE slot, my SWAG
is that turns off the 640x480 from the 8514/A. I really don't know if
anyone has tried it and reported the results.
Finally, the third party manufacturers documented the 8514/A registers.
You sorta have to do that if you wandt to clone the 8514/A...
The truth is out there...

To be sehr klar... I need you to take an 8514/A, install it into a
Non-AVE 16-bit slot [or a 32-bit if you can waste one], and bring up the
system. My SWAG is this was never done because everyone knows it goes in
the AVE 16-bit slot because the Holy Ordos IBM ordained it so.
Put the video cable on the system board VGA at the first boot, if the
8514/A is happy under set and view configuration, -MAYBE- it supports
VGA. At what color depth, I dunno, as the 8514/A uses the INMOS
IMSG171S-50 RAMDAC. Perhaps the mythical Mode 13 might help beat out
more possumbilities, but you have a 18-bit DAC [6-6-6].
My further SWAG is the 8514/A could do VGA if in a non-AVE slot, and VGA
drivers will do. Maybe.
You might need a video terminator, but since both VGA sources aren't on
the Video Extension, there isn't excess video signal on the AVE.
https://www.ardent-tool.com/video/Video_Terminator_Pinout.html
I'm not sure about the I/O address of the 8514/A.
We run the BVE XGA-2 with the BVE portion sticking outside the slot in a
Model 90 [which has planar XGA]. Having the AVE or BVE contacts hanging
in free air does not hurt the card or system.

Thinking without alcohol HURTS...
Finishing up the dishes, and I thought I had the answer, VGA for an
Autocad layers list! I was just about ready to disjoint my arms by
patting myself on the back, then a conundrum hit...
The 8514/A is aimed at the 1024x768 for CAD. Why not just use the system
board VGA for the layers list, and the 8514/A for the CAD drawing...
Further, let's suppose you run the 8514/A in a non-AVE slot so you can
use the base video [possumbility] on the 8514/A, but how do you switch
between CAD and VGA on the same HDD15 port?
Methinks determining the 8514/A registers is more significant than it
appeared... But imagine switching from 1024x768 to 640x480 to look at
the layers list, then switching back...

Thanks Louis - I only actually tried it in the AVE slot... I did not
get any video output at all. I don't know why I didn't think to try it
in other slots, even the 20 year old version of me would have at least
tried that... sigh.
I know the card was picked up, while using the onboard GFX, I observed
the usual system config changed message, and after loading the ADF in
set/view cfg I can indeed see the card listed and the slot its in.
I will try putting the card in a non-ave 16bit slot and while im at it
even a 32 bit one and report back when I get the machine backup on the
bench!
I will also connect a real monitor to it, I used a KVM for my testing
which in retrospect might have affected the outcome as well (probably
not, but maybe).
Thanks for the bit on the terminators, I hadn't stumbled across that
or even thought about that.
Have a few things to try here for sure before giving up, just figured
I'd ask around and see if anyone else had played around with this
before me.
Cheers,
Jonathan

Yeah, I suspect that you could sort of create a dual ahead sort of setup using one of these back in the day.
Keeping the layers on a 2nd screen would leave more room on the cad display, but I was hoping to only connect one monitor here.
You do raise a good question about how to switch back and forth on the HD15 port, who knows, maybe there is no switching in the traditional sense?
Getting into the registers is probably beyond me right now, well see how things go without going down that deep deep timevampire hole.

Hmm, if you tried the 8514 of 1024x768 @ 43.5Hz interlaced, I don't know
if that was supported.
VGA passthrough or [possumble] VGA from the 8514/A should be 60Hz and
compatible.
Good call on the KVM.

I looked at the images, there is no apparent outline for a second port
on the 8514/A, nor are there any solder pads for any AVE header, unlike
on the XGA.
Huh, maybe the XGA was considered for dual head?

Dears in most of the case the issue lies with the (incorrect) jumper
settings. Please look at my photos in ardent for a default (working)

I only found one set of jumpers, J5, for memory 0.5m or 1.5m enablement - mine has all chips populated, so the jumper is set to 1.5m.
I noticed this on the video/187-054.txt you sent :
" The IBM Display Adapter has VDI drivers to support the IBM
Personal Computer Graphics Development Toolkit, Version 1.20 (IBM
Personal Computer DOS) and IBM Operating System/2 Graphics
Development Toolkit. The VDI drivers are included with the Graphics
Development Toolkits. Refer to Programming Announcement 287-106,
dated April 2, 1987, for details.
For the IBM Display Adapter 8514/A, the drivers are written to
the adapter interface and will support the following modes:
o 640 x 480 -- 256 colors
o 640 x 480 -- 16 colors
o 1024 x 768 -- 256 colors
o 1024 x 768 -- 16 colors
The drivers will allow VDI applications to take advantage of
the new functions available in the adapter, such as improved
performance, 256 colors and high content. "
So it seems that indeed it can do 640x480, will have to play with it a bit more to figure out how to do that.
There is no configuration in the ready/set menu off refdisk, so I presume the actual floppydisk for this thing has some sort of additional config, perhaps that's why its not working.

What are you looking for? If you are looking for an item for 640, forget

speculation. But the XGA-2 does not have an item to change resolutions

Whoop - forgive me, probably my incorrect terminology here, I attached a screen grab of the refdisk I am referring to: https://postimg.cc/3yk7jLRF
I understand what you now mean, the configuration for the card is not alterable. Will try moving the card to the other slots tomorrow....
thanks,
Jonathan

The Godfather of "Our Thing", Peter Wendt, had a name for IBM Tech Cant,
Technoslovakian.
After enough time, you will adopt "Rightspeak" and learn to love the IBM
lash.
I still do not grok why they would need the VGA oscillator, maybe as a
reference? The VGA clock from the system board would be on the AVE, and
available to the 8514/A.
