    提取补丁：
    BIOS 文件，用任何 HEX 编辑器打开它，选择从 0 到 800 的部分，删除它，保存剩下的，使用简单的传输,把保存后的bios文件拖到AMISetup_IFR.bat上面，自动执行，生成_Setup文件夹，里面有我们需要的setup_extr.txt。从该文件可以查看两个地址：1、BIOS Lock VarOffset - 0x186 2、OS Selection VarOffset - 0x4E2 这样在第2步可以在这个地址0x4E2用命令修改刷入对应的值0x3。
    0x3 是对应linux系统
    刷写补丁：
    将 Boot_Shell_AMISetupWriter.rar 解压缩到任何空白格式的U盘。从它启动到 EFI SHELL，然后输入命令 amisetupwriter 0x4E2 0x3 刷写完成exit退出即可。顺便说一下，如果你重置了 BIOS，那么一切都需要重新进行。

    打上补丁之后开机时间大大缩短，60秒启动，据我了解，Asrock J3455m和J3455-ITX架构和bios相似，地址相同。

    华擎J3455m BIOS 1.80

    amisetupwriter 0x4E2 0x3

    请问BIOS Lock有什么作用？是否可以把华擎bios验证关掉刷修改后的bios？
