【求助】请问各位,官方bios更新exe解压后里面winflash的命令行使用方法
本帖最后由 kv0707 于 2017-3-19 10:25 编辑我想备份机器的bios,但是现在官方新的bios程序解压后(各型号最新bios的exe文件应该都一样)里附带的Winflash64.exe,命令行不会使用, 用自带的-help查询到 -bak是备份的命令,但是后面的路径和名称不会用,总是提示error 225错误要指定。请问有哪位朋友可以帮忙详细讲讲怎么样备份和使用备份好的bios文件刷机。谢谢
哪里来的这个单独文件?下载官方的BIOS更新包,运行WINUPTP,就会出来备份BIOS的选项吧。 HOPE 发表于 2017-3-19 10:48

hope大,exe解压缩文件在C:\drivers\flash\文件夹下,里面就含了这些包括bios文件。平时直接运行的是WINUPTP64.exe,但貌似没有备份选项了 运行WINUPTP64.exe后 再下一步? 可以备份的WinFlash64 /bak filename即可(要管理员)
