BIOS dump for the Lenovo ThinkCentre M62z all-in-one, with the name stating a Winbond W25Q64 flash chip, which holds 8 MB, packed as a 3.59 MB RAR archive. Knowing the chip type helps set up the programmer correctly, since the image must match the 64-megabit capacity. Technicians use this file to recover a desktop that will not post or shows a blank screen after a firmware fault. Read and keep a copy of the original chip, then erase, write and verify the new image to be sure the flash took.
