EC ROM read from a Macronix MX25L25633F in a WSON8 package, archived as RAR and associated with HP and Quanta board DAX8VPMB8E0; the trailing digits are a programmer timestamp. The MX25L25633F is a 256Mbit (32MB) part, so the dump reflects a full chip read. It serves to restore embedded controller and system firmware when a board shows no power, fan or charging response. Confirm the chip marking and board number match yours, keep a copy of your own read, and verify after writing.</description>

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 →
