I have this sweet 386 I've been putting back together after a full tear down cleaning. It boots just fine but it complains about no CMOS battery. I have scoured the internet looking for anything on this motherboard and where a BIOS battery might connect. I'm going to assume it's at the connector near the PSU input (blue arrow I drew) but I have no other ideas. If anyone has any information about this board, I'd be happy to hear it.

Specs:
Manufacturer: Multitech/Acer MPF-1100
CPU: 386DX -20
Ram: 8MB
MB Part Number: 48.11007.003A1

Any ideas?

Thanks. I ended up using my DMM and determined the two right pins on that socket were ground so I hooked a CR2032 battery up to the first and third pins. It's now holding CMOS settings. Thanks!
