Mouse port? 🤣

That's actually S-Video, a display connector for some TVs and even some monitors.

I could be wrong but I think it's a bus mouse connector. They mention it in the documentation that I do happen to have.

From a document I found online "1992 || 109-00189-40 (ISA),109-23000-10 (PCI) || Graphics Ultra Pro || ISA,EISA,MCA,VLB,PCI || 1 or 2MB VRAM || ATI68875 || 1280x1024x256, 1024x768x64K, 800x600x16.7M || Analogue VGA/SVGA, bus mouse (ISA,VLB) || Similar to a Mach8 with integrated VGA and support for higher colour depths || 225px|center|frameless|Mach32 PCI(VRAM)"

Here's a close up picture:

Is it same connector as Microsoft InPorte bus mouse?

Hey man a thousand thanks for that link, however... I have no idea what the "Address" section means. So I can now change it, but no clue what changing it means. haha. Any advice? My main concern is that when I run a test on the mach32 it says "irq jumper not set or irq conflic" or something of that nature. Am I on the right track?

Also if the switch is up is the on? Or off? 🤣

Also, I think I have one of those mice, if you give me a bit I'll dig it out of the box and plug it in!

Was about to post jumper settings and mate, it says on the dip switch where OFF position is 😀

Even and odd chips are the BIOS EPROMs, BIOS image itself is divided into two images which consists of even and odd address values from original image, it was done in order to form a 16 bit data bus for the card as each EPROM is only 8 bit wide.

The big chip, which you labeled 5, is a ramdac.

BIOS address settings lets you chose where video bios will be stored in your RAM, just set it to C8000h as it is typically reserved for video bios.

Great info dude, I just finished trying every combination of switch settings based on the link you provided, and I tried them in reverse in the event that I had on and off reversed on accident. Interestingly, the only combination that works is when all switches are pushed up (off I think). Every combo fails to display video. So far I'm working on a totally clean install of DOS 6.22, I've installed drivers for the card as well. Still getting the IRQ error message.

What was the MS-DOS performance of this card/Mach32 chipset?

I seem to recall this is the same card I ordered from a local reseller and it had TERRIBLE Doom/Quake performance, but I'm quite possibly very wrong.

How is this card NOT a Graphics Ultra Pro? Looks like one to me.

I'm new to DOS graphics entirely, this is my first card. It's going in a Packard Bell PB650CD (486sx 8mb ram, soundblaster). I imagine it's better than what I had, and I found it for .99 cents at Salvation Army.

Anyway, the idea of drivers seems to be different with this card. It's talking about drivers for specific programs, not an overall graphics driver. Does every single program need its own graphics drive to work with this card? What if I installed this card and started playing a DOS game, am I getting a benefit just because I plugged it in or do I need a driver for the game? I'm very confused by all of this coming from a modern PC background.

I'm starting to think it is a Graphics Ultra Pro, I've been trying to match it all day. But even though I know it's a Graphics Ultra Pro, I still have no idea how to install it or use it with DOS and DOS games.

If you got the card working and you intend to play DOS games with it, you shouldn't need any drivers for standard VGA-mode games (300x200). Just try loading a game and see what happens.

In case you want to play games in SVGA resolutions (such as 640x480) you might need to load a resident program such as UNIVBE before starting the game, but chances are that an ISA card on an SX just won't do well for those later "high-resolution" games.

Interesting. So, I disabled my mach32 and switched back to my motherboard's onboard VGA... I actually lost frames per second. SO on the graphics card I got 24.4 FPS in Superscape Benchmark. Without the card at all I got 30.1 FPS. This is very odd. This is without any software installed besides DOS, no drivers, no utility, nothing at all.

Sold one of those cards aways back with the original manuals and drivers. It's a mouse port and not a tv out

And it looked like a ultra pro

Not surprising that the integrated VGA is faster in DOS. Most (if not all) VRAM based cards are slower to some degree in DOS than their DRAM counterparts. I would only use the Mach32 if you plan on running windows. BTW, do you know if your integrated graphics use local bus?

Also, the round connector on the card is a bus mouse port. It should be compatible with the microsoft type. I don't think an S-Video cable would physically fit in there even if you tried.

No clue if it's using local bus, no clue what that even means. There's a picture of the machine, it's a Packard Bell PB650CD (486sx 50mhz). How can I check if my motherboard graphics are using local bus? And what's the significance of that?

ISA bus (what your Mach32 uses) runs at 8MHz. Local bus allows peripherals to run at the same speed the CPU talks to memory, in your case 25MHz (because your CPU is clock doubled). Local bus has the potential to be several times faster than ISA. Because your graphics adapter is integrated, you'd have to read the manual to find out if it uses local bus...maybe there are utilities that can tell?

I suspect the integrated graphics might be on a local bus. I personally wouldn't bother with an ISA graphics card in a 486. If you want performance you need a motherboard with VLB or the rare PCI slot. If you don't want performance, why bother with add-in cards at all?

I will also say that the VLB Mach 32 gave me all sorts of grief when I tried one last year. Swapped out for an Orchid Kelvin 64 and it was WAY faster than the Mach 32.

Just for the heck of it? 🤣
And things like compatibility or certain features may also be a reason to do so.
