Dell BIOS dump for board 19746-1, a number that follows the Wistron pattern, with a note that the OS is not working. Although the name says 8MB, the file is 16.0 MB, so it may be a combined image or a mislabelled read; check the size before writing. The OS not working remark suggests it was read from a board with a boot fault and may not fix one. Use it only as a reference or a last resort, and always back up the original chip before programming.
