BIOS for the Positivo POS-MIG31AG desktop, an OEM system built on the MSI MS-7529 motherboard, version V2.4B6, in a 415 KB rar archive. MS-7529 is MSI's in-house board code, and Positivo machines commonly carry customized firmware for it. The dump is meant for restoring a dead or corrupted BIOS by writing the SPI flash with a programmer. Back up the current chip, confirm the image size fits the installed flash, and verify the board is indeed the Positivo variant, since retail MSI images differ.
