Per the manual, this board has few options to add a mouse, but I'm not sure how would I go about it.

- This should allow attaching PS/2 mouse connector
- Manual is showing 6 pins to attach to, but I can't tell by looking at the motherboard which of those 6 pin connectors are which
- What kind of connector would I use here to attach to the pins? I assume there's no standard and I would need to attach individual pins to a PS/2 bracket?
- How do I know if the motherboard's BIOS supports PS/2 mouse? Is there any way to detect support for PS/2 in SW? I have a chip programmer so if there's a way to read the BIOS and identify PS/2 support, how would I know what to look for?

CN12
- Manual says this is a Mouse Connector. There is already a 5 pin connector on the motherboard.
- How do I use this connector? Is this PS/2 or serial or something else.

Attaching board pictures and original manual for reference.

Thank you.
