The BIOS write‑protect switch is located on the rear panel of the computer chassis. Setting the switch to ON allows BIOS flashing with a BIOS Flash tool but does not protect against malicious virus modifications. Setting it to OFF blocks BIOS flashing, providing protection against virus‑induced BIOS changes.
For OS installation or hardware changes, set the switch to ON before proceeding, then return it to OFF after the system is running normally. The guide also advises keeping the switch in the OFF position during regular use to maintain BIOS protection. This manual is written in Chinese.
