ASUS BIOS capsule for the H110M-CS motherboard, version 4210, in .CAP format at 16.0 MB. CAP files are normally flashed through ASUS EZ Flash or USB BIOS FlashBack, where supported. Before writing one directly to the SPI chip with a programmer, the capsule header usually has to be removed. The 16 MB size points to a 128 Mbit flash device. Confirm the exact model on the board silkscreen, and keep a dump of the original chip to retain the MAC address and serial data.
