Frequently asked questions
What should I check before flashing the HP ET866 BIOS?
Read the original chip with a programmer and save two copies before writing anything. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
