Quite fascinating. I have the exact opposite situation. The 126 Rom seems to default to 75Hz while the 106 Rom defaults to 60Hz, in my case. I use an Extron RGB2HDMI 300A which can do almost everything you throw at it (15Khz - 120Khz no problem) and a Hauppauge standalone HDMI-recorder. The Extron RGB2HDMI 300A converts even the strange 31Hz resolutions of the 126 Rom but sadly shifts them so much to the right that i cannot get everything on screen.
That's really odd!
I'm using a 1280x1024 LG panel from the early 2000s. I need to replace the caps on the power board in my ViewSonic that can handle just about any video signal including from a Toby, which is useful (most LCDs don't like the output from a Toby).
On my card, the jumper in the same location is actually pre-populated with a header and called J4. It connects to pin 151 on the ViRGE chip, which is "Enable Feature".
I don't know where it goes on my card on the Virge chip but on the PCI-bus it goes to INTA and is used for the mouse in some kind of fashion. Without the Jumper, it just goes to an unpopulated feature connector.
F/A-18 Hornet supports multi-monitor views. I've never actually tried it, but if you set up 3 monitors you can have front and sides on three displays.
So I tried a DX out of curiosity with no luck. It probably has a different VID and so the ROM doesn't like it. The various chips do have differences, but are pretty similar... A competent hacker could probably bodge at least 2D to work...You guys seem to be having a lot of fun
I was hoping I could join in, but I'm not sure:

I've been using this card in an old PC just for booting into DOS to test and flash PC video cards. I grabbed it from a scrap bin many years ago and kept it around because it worked, and I thought it was a boring card with no Mac equivalent, so I wouldn't be tempted to flash it...
The little bit of research I've done makes it sound like the Virge/VX (988) is the same as the Virge you guys are using (325) but uses VRAM (early term for dual ported memory?) vs. standard DRAM. I have no idea whether that would make it different enough for the same firmware not to work.
Hang about!? Where is that from?
I simply modified the Rom to see the DX in two locations.Hang about!? Where is that from?
Perfect - I was wondering if it would happily do 2D with just an ID swap. I'm just much less proactive that you are!
A Virge GX (SGRAM) works with the same Rom but is not usable since i get A LOT of errors while blitting and screen drawing.
The Mouse problem was because there were damaged traces on the back of the card.
The first mod changes the device ID in the PCI Header from 5631 to 8A01.
I made some errors when i manually typed the bytes in the comment.
I've spent a while digging around but haven't pinned it down yet. If they've made a function to set registers in the card and called it from elsewhere, frustratingly the register and values will be separated. Also parameters might be stored entirely separately in another resource.
