About this board
This thread is for the Biostar TZ77XE4.
Compare the board number printed on the PCB (between the PCIe slots or near the CPU socket) with the files before you flash. Board revision: 5.1. Match the revision as well as the board number.
What this thread covers
- BIOS (full SPI chip dump, .bin)
Typical reasons to reflash: no POST after a failed BIOS update, a corrupted BIOS chip after a power cut, or a board that powers on with no display.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
If you have a working file for this board, please share it below. More files: search Biostar TZ77XE4 in File Finder.
