BIOS and EC firmware for an ASUS B1500C (the name spells it AZUS) with an 11th-gen Intel CPU, board revision R2.1, which the uploader marks as fully working. The 7.50 MB RAR should hold both the main SPI image and the embedded controller firmware, which handles power, charging and keyboard functions. Back up the original chips with a programmer before writing, make sure your board is revision 2.1, and check that each image size matches its flash chip.
