Need BIOS for ASUS C523NA

[mferna14]

Dear kalilinux25., I am trying to repair ASUS ChromeBook motherboard. The BIOS is de-soldered (Physically NOT present) & no trace of it. I know from the previous ASUS Chromebook model repairs, it's a 128KB BIOS 1.8Volts. The motherboard is C223NA REV: 2.2, I even have the serial # of the laptop for where this motherboard was removed in March 2024. ChromeBook Model C523NA-BB01T-CB S. No: M5NXCV04T229185., Now I need a working BIOS BIN file so that I can complete this motherboard repairs & keep it as a spare in my stock. Can you help me re-building this file. I have no BIN file to upload except fro 2 motherboard photos.Thanks in advance dear
