I don't recognise it, and google image search doesn't recognise it, but if you get a picture of it at less of an angle, more flat, then google image search might give a better ID.

Otherwise, I would suggest unplugging the LCD connector to see if it defaults to VGA out. I realise you might not want to use it like that if you are trying to troubleshoot LCD, but if we get the POST screen we may be able to do a better ID from the BIOS screen... possibly also, the config is in the BIOS setup and the battery is not holding settings still. Those Dallas clock chip/battery/CMOS RAM modules are usually good for 15-20 years maximum and that one is 27 years old.

Hello, new here and I have a problem with a
old SBC in an industrial application. It says "486 5x86 sbc ver g9" on the card. It has an lcd screen attached but it has stopped working so I pluggd in an external screen to make it work. But to activate the vga port I've been told to change some jumpers. The problem is that I cant find the info anywhere online. Does anyone have a manual or info on the topic?
Sorry for bad language.
