Safe BIOS read/write checklist

Checklist before you touch an SPI BIOS chip on a customer board. Before read - Note board PN, chip markings, and whether the machine currently boots. - Use 3.3 V programmers only unless the chip is known 1.8 V with a proper adapter. Read - Read twice, compare hashes. Store the original dump before any write. Write - Prefer donor dumps that match board revision and EC/ME expectations. - Cleaning ME / unlocking regions is advanced — wrong cleanup bricks the unit. - After write, verify the chip contents, then first boot on bench PSU with current limited if possible. NLCRC members can request dumps via BIOS request; staff confirm before publish. Downloads appear in BIOS library / Downloads when cleared.
