Can't reset UEFI BIOS password
hello,
I recently bought an old or first-series UpSquared on ebay, whose model number might be: UP2 UPS-APL4FF-A20-0432
It boots fine, but I want to get into the BIOS menu to enable an mSATA device that isn't being detected by Debian (or various other Linuxes).
When I press Del or F7 right after powering up the SBC, it brings up a blue-and-white text-only password prompt. It lets up to 3 attempts be made and then locks the machine.
So basically a BIOS password, but unplugging the CR2032 button battery for > 2 hours hasn't cleared it.
And the password doesn't seem to be [blank], upassw0rd, admin, root, password, upsquared, UpSquared, Up2, counting up or down from 1-6... or anything that occurred to me.
I'm stumped. Is there another battery? Is a password persistent on the emmc even though it's been zeroed by the Debian installer? Is this some kind of bespoke security feature added for whoever was the original owner?
I'd be hugely grateful for any help. I haven't used an UpSquared before and I can't return it because it took me a few weeks to find a power supply and mSATA card.

Could you please provide the serial number to me?? (Cxxxxxxxx)
I will check the bios password.But the default should be blank or upassw0rd.
