&pFirmwareTableBuffer就是原始数据，自己拆数据吧。（需要出演示代码怎么拆数据的，随时关注这一楼吧，说不定哪天比较闲的时候就拆一下更新了，其实这里的数据有很多C或者C++现成的开源代码示例，只是PECMD2012是脚本语言大家都玩的比较少罢了也没人愿意费劲折腾）
写入一个文件，用winhex查看：- IFEX %&CurDir%\SMBIOSTableData.Bin,FILE %&CurDir%\SMBIOSTableData.Bin
- GETF -bin &pFirmwareTableBuffer,0#%&GetSystemFirmwareTableRet%,&SMBIOSTableDataTemp
- PUTF %&CurDir%\SMBIOSTableData.Bin,0#,%&SMBIOSTableDataTemp%
附件里是3.3版的规范，最新的应该比这个版本高，对着看下先。

下面这段是演示代码之拆了BIOS_vendor的数据，其他的自己对着慢慢研究吧，具体要参考上面的PDF资料。
注意：请使用网盘中最新的PECMD才可以，2022.06.09更新的PECMD。
