BIOS for the ASUS Z87M-PLUS desktop motherboard, version 1106, in a RAR of about 9.10 MB. The archive likely contains the vendor image, which can be written through the board's update utility or, when the board is dead, directly to the SPI chip with a programmer. Vendor files may include a capsule header that must be stripped before programming. Save the current chip contents first, since they hold the MAC address and serial data, and verify that the image fits the flash size.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
