Just got this card today and having trouble getting it to work in my 486 system (Gateway 4SX-33/Intel Classic R). Could just be junk and I'm scratching my head thinking it's my own ignorance of old hardware.

It gave me an error the first time powering on, something like "unresoved I/O expansion NMI, memory parity failure" and there was a prompt to shut off NMI. I powered it off instead of choosing an option, now the computer will only POST with the MFBEN jumper removed. Driver setup can't detect the card and gives an error when I try the different address options (wrong card or bad address). What's also concerning is the big chip gets hot to the touch very quickly.

Curious if you added the ram or did it come with it ? I suggest pulling the ram out and try get the card working first. I have never used non-parity simms on a SB32/awe32 though theoretically should work according to some....

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

I thought these cards were supposed to take non-parity SIMMs? RAM is brand new. Clips are broken but it seems tight enough. No difference when pulling the RAM.
That's the thread I was looking at before posting. I managed to install CTCM but the driver install fails because I have the wrong base I/O address (or it's not seeing the card at all).

Check for physical damages on the board - the card looks like had a tough life 😀 There may be also some shortages inside RAM slots.

Yikes! I just discovered some of the big chip's pins are bent and likely shorting against each other. Might explain why it was getting abnormally hot.
Does anyone on this forum do mail-in repairs? I don't think I can straighten these out without breaking them and/or lifting pads.

Just be gentle...

That looks ilke something that could be fixed with the blade of a sharp little knife (maybe a razor blade). Just slide it between the bent leg and the one it's shorting onto. Doing that gently should be enough to free them again.

Agreed with pulling out the RAM. As soon as you hit problems, you want to only change the absolute minimum every time. So first check the system boots & is stable without the card, then add the card without the RAM, finally, add the RAM one SIMM at a time, checking before adding the second one.

I'm not so good at being gentle with tiny components and the legs on this chip are very fine. I tried to straighten them with tweezers but they won't budge. They may be solder bridged but I don't have a microscope to get a clearer view. I did try hitting the legs with hot air (very much a novice but I recently bought a station) hoping to at least avoid the risk of damaging the pads but there was an audible pop and I may have fried the chip.
