BIOS image for the P8Z77-V PRO desktop motherboard, with the name pointing to revision 1.02. The 168 KB RAR is heavily compressed, so the extracted file will be considerably larger and should match the board's SPI flash capacity. Such dumps are used to recover a board that fails to POST after a bad flash, by writing the chip directly with a programmer. Check that the board model printed on the PCB matches exactly, and read out the existing chip before overwriting it in case the original is needed.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsbiosfree. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
