BIOS image read from a Winbond W25Q128BV, a 128 Mbit (16 MB) SPI flash, for a device labelled 15-G3, packed in a 9.17 MB zip. The name gives no brand or board number, so confirm the exact model and motherboard before using it. Such a dump is written with an SPI programmer to recover a unit that fails to boot. A companion W25Q64BV image for the same 15-G3 exists, suggesting two flash chips; back up both originals and check image sizes match each chip.
