I have this RAM card in my collection for quite a while now. Sadly, I wasn't able to figure out model number or manufacturer, so I also have no idea which driver is needed to get the card working. Anyone here can shed light on it?

Those DIP-switches sure are interestingly placed. I sadly have no clue what card this is, yet I am fully intrigued...

The switches are to set starting adress of addon ram.

i found one here:

It seems the card can fill up XMS Memory, and also supports EMS
so chances are there that you can set both EMS Memory and XMS Memory with each of the DIP Switches.
So you have both types of Memory.

You may want to try the DIP Switch settings on the Photo.
As the Seller states he tested the Card with 4x256Kb RAM on it.

For XMS no driver is needed, the BIOS should simply count it up.

EDIT:
Are you the Seller of this Card ? (identical pictures)

Yes, that is my card.

The problem is that I can't get anything than 4x 256 KB as XMS working.

Is there a FCC ID on the Card ?
so you can find out who manufactured it.

No, it doesn't! That's a cheap taiwanese RAM card.
