Want to back this 40pin chip up. Cant find it on my eeprom reader list. I am a novice at this. Using a USB Top835 to back up my older computers bios.
Thanks for any info in advance.

To identify it if your reader can't autodetect it, you will need to remove the sticker. There is software that can read and save it in situ, but I have never done that, so will let someone else advise on that.
See my graphics card database at www.gpuzoo.com
Constantly being worked on. Feel free to message me with any corrections or details of cards you would like me to research and add.
This looks to be the keyboard BIOS/controller. If I'm right, its contents cannot be read with simple means (including most of the cheap USB programmers).

Nothing under the sticker.

How would you replace it? I want to make sure that I have future security in case of a malfunction.
short answer: you take one from another motherboard.
This is why i typically throw NOTHING away.
It is a mistake to think you can solve any major problems just with potatoes.

Agree ! It is a KB controller. It is a 8042 controller variant. Best way to replace it is get another KB controller chip. It generally has control logic, small scratch ram and 1k to 2k of pre-programmed ROM plus some peripheral interface logic. There is no way to directly read and save the rom part and would do no good since you cannot flash another KB controller with same rom contents. Any KB controller from same era motherboard should work just fine.
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
Thank you all very much.
