BIOS dump in RAR form for a board labelled MIB75R MH, with the SG tag and Wistron-style number 11068-1, intended for a W25Q64 flash chip. The W25Q64 is a 64 Mbit (8 MB) SPI device, so the image inside should match that capacity. Wistron uses five-digit numbers with a dash suffix on its boards. Use a programmer to write the dump when the firmware is corrupted, after reading and saving the current contents. Confirm 11068-1 on the PCB and the chip marking before flashing.
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.
