Welcome.
There is this pack here, but it doesn't specifically list your model: https://www.vogonsdrivers.com/getfile.php?fil … 786&menustate=0
You probably found this one pretty quickly and would have seen that it's just bait. But the filename shown here "AdvanSys_ABP-5140_5142_driver_and_manual.zip" could aid your search.

Here's the Wayback capture of the original download page. The download links look dead but you can see the original file was called "dosfiles.exe" https://web.archive.org/web/20010331080028/ht … /fastultra.html
Have a look here too. Do a ctrl-f in the descriptions of each CD and see if anything looks promising: https://archive.org/search.php?query=ad ... oftware%22
Or maybe weedeewee has the drivers:

My google & archive fu is letting me down, so I'm throwing this question out here.
Does anyone have a fully equipped Advansys ABP-5140/42,
ie the one with the floppy drive controller on board & the eeprom for the bios
and would said person be so kind to share some
clear photos of the card
and a
copy of the bios?
I've got one without floppy & bios and want to try to add the bios to it and if the chips can be found, the floppy controller as well.
Thanks.
