BIOS firmware package in RAR format, 689 KB, for the Dell Inspiron 1545 built on Wistron mainboard 08212-1. The name also references u23, which most likely identifies the chip location on the board that the dump was read from. Wistron produced this board for Dell using its five-digit project code and revision suffix. Use it to recover a dead or corrupted board with an SPI programmer, after confirming the revision on the PCB, checking the image fits the chip, and saving the original contents.
