BIOS and EC firmware for the Toshiba Satellite L755 on the Quanta board DABLBMB28A0. The DA...A0 code follows Quanta's numbering, where the middle letters identify the project and the final characters give the revision. The archive should hold the system BIOS plus the keyboard controller image, used when a board will not power up, loops on start or has lost its EC code. Read and save the original chip with an SPI programmer before writing, and compare the image size with the flash capacity printed on the chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
