X2100 has two bios chips?

So, uh, this probably isn't going to improve anyone's opinion of my observational skills, but I just realized there are two bios chips on the x2100 motherboard? One's by the mpcie slots and is a Macronix MX25L12835F, and the other's by the USB-C port -- that one's a Winbond 25Q80DVSIG. Finding this gave me a bit of a scare -- I'd already desoldered the chip I believed was the BIOS chip, and finding another candidate really shocked me.

I checked my command history, and I'm pretty certain all my interactions have been with the former, so I'm no longer quite as flustered -- but what's the other chip for?

Pretty sure the macronix chip is the bios chip. There are tons of other ways machines can use flash chips
